So, yesterday I decided I'd bleed the brakes on the 1982 CBX project. Bled the front brakes, no problem. The rear, I pumped and pumped, but could not get fluid to the caliper. Verified flow from reservoir to master cylinder and from MC to caliper and through the caliper. All good, so the problem was the master cylinder. Removed MC and found dried white powder and the piston was seized in the cylinder. Figured no problem, just remove the piston and buy a rebuild kit. Well, this was a no-go. I spent half the day trying to get the piston out of the MC and another half the day online looking for a stock replacement MC. No dice, they are unobtainable it seems. Who knew parts are hard to find for a somewhat rare 42 year old motorcycle. :) I did some more research and this morning got up early and modified an old banjo bolt so I could use a grease gun to hydraulic the old piston out of the bore. It worked! What a PITA though. I'm 59 years old and learn something new almost every day. Life is good. I got my info on a Facebook page, of all places . . .

Been pretty busy despite being fairly sick with covid.

2009 Fit AC compressor failed, so I replaced the; compressor, condenser, and expansion valve. 2 years w/o AC was long enough.


1994 has been up on jack stands for 3 months waiting on custom suspension. It finally came in during my covid down time, and in between feeling like trash I managed to get everything buttoned back up.

Most everything in this world isn't designed for taller folks, and being 6'2" and a big guy I am sick of messing around with things that are just a pain in the *** to use. So I mod'd this US General cart for pressure washing duty. The tires are from the original Simpson cart that came with the pressure washer.

Great!
Hey wait a sec.
You completed an old project
And did several others
While sick.
Wow! You making me look bad.
I am sending a 1991 for you to recondition.

Feeling inadequate now

I have this same cart for my meat processing/grinding equipment. I keep it stored in my workshop and after 5-6 years all the paint is falling off in sheets (assuming it's powder coated) and underneath the metal is rusted. My guess is they did a really poor job of prepping the metal prior to the powder coating so at some point I'll be disassembling and repainting it. Pain in the rear.
That's pretty much how every powder coated truck part I've seen fails including the frames and bumpers.

I like the modified banjo bolt. I might have bolted that rear master to one of the front caliper lines to push that piston out, but then I would have needed to re bleed the front caliper. Probably less work the way you did it.

Replaced the carb, air filter, spark plug and fuel line on my GF’s mower. All genuine Kohler parts (not the line though).


Runs great, but I’m still not happy about the non smooth movement of the automatic choke on the muffler. It’s ordered, just gotta wait for its arrival.

Not necessarily. My old leaking down car went to full pressure at the turn of the key. Are you reading the pressure with a mechanical gauge, or through the ECU? A lot of ECUs remember what they were doing when they shut down and put that data out for a second before generating a new snapshot on startup.

Does it hold pressure overnight?
So the mystery continues.lol


Tuesday morning I put the gauge on, as suspected, long cold start, then I drove about 10 minutes and parked in a hot sunny parking lot.

The gauge sits at 65 psi running, drops 5 psi instantly when the truck is turned off. After about 3 minutes not running, there was a 4psi loss. After 3 hours it was down to 40psi. After sitting for 6 hrs it was down to 19 psi, but still started immediately with no issues.

Drove 10 minutes home.

Tuesday night, around 11pm, after sitting for about 6 hrs, it was at 19 psi, but started immediately with no issues.

Wednesday morning, after sitting over night, around 7 hrs, it was at 19 psi and had a hard start. Took three tries, each try was a 6 second long crank to get it to start.

Here’s where I’m hoping someone has a light bulb moment.lol After the Wednesday morning long start, I only let it run for a few seconds, then a few minutes later I tried starting it with 60 psi. It took 3 more 6 second tries to get it started.

This is where it gets really weird. I drove about an hour and a half, then I let the truck sit in a hot sunny parking lot for about 12 hours, there was zero psi until I turned the key, and the truck started perfect with no issues?????????

So to sum up my last two days, it “seems“ like it has long starts only when cold, despite what the fuel pressure is. “Seems” like it doesn’t have long starts when warm, despite what the fuel pressure is ?????

What are the coolant temp and air intake temps on a scan tool.
Does does the mass air flow read 0 when it's not running?

The lost fuel pressure is going somewhere either back into the tank or a leaking nozzle into the manifold, even though the fuel pressure on the gauge jumps up with the key turn it will take a bit to push the air out of the tubes feeding the nozzles.
I think you posted that you replaced the spiders already was it a new or rebuilt set up OEM or Dorman?

I want to thank everyone that’s helping brainstorm this issue.:beer:

The injectors were after market from AutoZone, I don't remember the brand, or if it was rebuilt, I’ll look at my receipt later.

I was thinking just like you and Kay, that the problem was air in the line from a slowly leaking injector or regulator. But the fact it sometimes starts perfect at 0 psi, I’m confused.lol

I Haven’t checked anything with a scan tool, other than to check if it had any codes, which it didn’t.

I’ll see if the local parts stores scan tool is able to check those later.

And by the way, it sat all night, it had 0 psi till I turned the key, and it fired right up just a minute ago:wtf:

Just checked my receipt, it‘s a rebuilt with all bad reviews:rolleyes2 guess I should have looked at the reviews first, but they were the only store in town that had one in stock.

Oh I wanted to mention, the type of spider injector I have has no return line to the tank. The original had only one hole for the fuel line, the aftermarket one had two holes for the fuel and return line, but the return line hole was plugged.

It’s starting to look like I’ll be replacing the spider injector again.

Its still a bit of a mystery to me why it sometimes starts fine, even with 0 psi though.

Cleaning out old stock, broke up and took old particle board shelving and other **** lumber to the dump, and burned some. Getting rid of old spray paint by using it up. Son had some colorful paint left over from a project he did for his fiancee's niece. I used it up as a part of rebuilding a wheelbarrow. I'm not really a precise-painter kind of guy. BTW, the rotted handles replaced by some PT, ripped from an old 2x6 deck joist. The wheelbarrow used up two used cans of spray paint, a used spray can of stain/poly (handles), and a used can of clear poly. It is good to get this stuff used up for a purpose.

Feeling inadequate now

Even when sick there is something in my brain that doesn't allow me to really just lay in bed and relax. Plus when I get up and get moving I usually feel better vs laying in bed. I also have a damaged rib from playing volleyball so laying in bed isn't all that comfortable.

You can send me your 1991 but yours might come back with the dashboard and associated items from my 94. I've been itching to do the 90-93 dash swap. ;)

Excellent way to use up spray paint! I have some colorful garden tools for the same reason, but nothing in pink and purple!!! Love it!

Replaced the carb on my wife's Echo chain saw which had been sitting for a couple years waiting for me to 'get to it'. After priming and choking it started on the first pull. Amazing how that works. ;)
Now she can join me cutting up the remaining downed tree resulting from Beryl coming through here. :cool:

someone say 91? My 2nd owner 91, was my mom's car. Was completely stock, except for the new top they had installed, when I got it. I've added a few goodies here and there.

Last night I grabbed a beer and the lawn tractor from the garage to unload another parts donor truck and get it in the driveway for gutting. After that it was a few tools for random things like reseating the bead on the lawn tractor tire when it decided to come loose while mowing. Sounds like a trainwreck but I swear it isn't lol. That tire leaks and while it seemed good enough to mow on I must have rolled it off on the sidewalk or something. Fixed in a min and no issues thereafter. A productive evening for sure.

Last night moved the Miata back to the garage. Tonight I will get the rider moved to the shop to check oil & tires before mowing front either tonight or tomorrow. I was going to put the mulching blades & plug on before mowing again but the front yard is a tall weedy mess. The boy says it was too hot to mow after work while we were sunning ourselves on Maui for the last two weeks so now yard is an overgrown, weedy mess. After mowing the front, I will install the new blades/plug and a new engagement cable. We have never mulched at this house, figured I would give it a try during the slow growing season.

Very nice! Just an fyi you can pull/massage the headlight covers up to match the hood better. They get pushing down from mechanics/people leaning on them as the sheet metal isn't braced for fat lazies to lean on.

Fought the fridge and WON!
Didnt loose anything.
Freezer temp climbing by the day, fudge pops getting soft and we can't have that. Thought it was the usual suspect, defrost heater. Nope. Replaced heater enough to keep one on hand.
Charge was on the high side and I guess it took to really hot days for it to kick out. After messing with it for 2 days with some time between attempts. Yesterday started from scratch. Comlete vacuum and charge by weight. Yeah I have small cans and a postal scale. :rolleyes:
Close enough cause It worked.

20240719_012424.jpg

Also got some cheap $42ea tires for the DD beater 81 Rabbit. Mounted on the Horrible Freight Emanuel tire changer.
Old set 0507 date code and used up. Fronts have some tread left, pic rears. It was time.

I believe the difference is probably going to be if the line completely emptied after the spider head and/or if the engine was hot enough to vaporize all the liquid fuel out of the intake or laid there waiting for a valve to open and soak the plug.

If you want to you could pull the spider out rehook the wires and fuel line put each injector in a cup turn the key on to build pressure and see it or how many drip.

I figured I would check that when I replace it. Just to see.

I used my little endoscope camera through the throttle body to see if the fuel pressure regulator was leaking. Didn’t see anything, but I now watched for a minute or so.

It’s got one on the injector body like in the pics below. Since it’s mounted under the intake manifold, it’s a little difficult to check.IMG_0072.jpegIMG_0071.jpeg

Yea you would have to pull it out and hook up the fuel and wiring to it to check it I've found a few bad ones that way.

Since it's starting at varying pressures, I'd kinda be willing to write off the injectors as the problem, but cranking it over looking for bad injectors couldn't hurt. Have you checked the crank/cam position sensors? Are you getting spark on the cold starts?

i searched before posting, and didn't find a thread like this soooo.......


today, i cleaned up some junk that was in my way. i replaced a bad light fixture, fixed up a tiller, and cleaned up a few things.

how bout you?
Yesterday I scored a good sized compressor and added the 220v head. I'm super pleased for the price and that it was 12 minutes away off Craigslist - and I didn't even get murdered !
The db palatable at 6" 84 and at 12 feet it's 74.
It's nice to get back some of the tools I sold or donated years ago when a job forced a move.

Kay, you and I have a similar trait, a bad memory.lol Yes, the cam and crank sensor were recently replaced for a separate issue. It does have fuel pressure and spark during the recent long cold starts.

I was in the same mind set as you, thinking the apparently slowly leaking injector was irrelevant, but like wrench97 mentioned, it could be random because of the intake valve being opened or closed as the injector leaks.

I don’t want gas pouring into a cylinder either way, so I’m gonna change the spider injector again anyway. If theres still a cold start issue after that, then I will keep on chasing it.
Also, does it cold start with a jump?
Never tried jumping it, as the battery is fully charged and less than a year old. No signs of battery issues, cranks long and hard when needed.

What's the voltage? Have you done a compression test?

Worked on getting all the electrical stuff mounted for the new A/C system I’m installing in my brothers 71 bronco. Not a lot of room behind/under that dash. Glove box will now house the ECU, relays, fuses and the original fuse block.
