Re: what did you do in your garage today?
As far as what I did in the garage yesterday.......
I was going to help the neighbor lady's son replace the fuel pump on his Silverado. His truck hasn't ran in almost three years, but he's moved to Georgia and came back up to try and get his truck running. His mom asked if I could help him. We ended up pulling it down to my garage as they don't have a hell of a lot of tools. First off, the truck is a '98 and contrary to what a lot of people tell you as far as car people and mechanics.....You do need the special tool to pop the fuel lines off.
So we got the bed off, or set back far enough. I had him turn on the key and no sound out of the pump. Then in looking, there was a connector pulled out but it made no difference. We get the old pump out, put the new pump in, hit the key and she fires and quits, so I figured there may be some air in the lines. We could keep it running by dribbling gas down the throttle body. It would run, but run a little rough. As soon as we quit dribbling gas, it would die.
He replaces the wires, the distributor cap, fuel filter, plugs, control module, and now the fuel pump. I asked him what happened when it quit running. He said it has a newer engine out of a Denali in it, he got home from New York, parked it, went to start it the next day and nothing.
He's had mechanics look at it and they couldn't figure it out although they did throw some of those new parts at it.
Thank God for the internet
I did a search on a 5.7 firing then quitting. There were some recalls although they were for Impalas, Malibu's, and Grand Prix's for the ignition switch. Long story short, somehow his truck jumped into the security mode. I happened to get in to start it and saw his security light flashing, asked him about it, and he said it's been doing that since he tried to get it running the last couple of days.
It takes roughly 30 minutes to get it OUT of the security mode, 10 minutes at a time. Turn the key to the on position for 10 minutes, then turn it off for 20 seconds, try to start it. If it doesn't start in ten, then you have to do it two more times just like that. You have to keep an eye on the Security light on the dash to see whether it is flashing or if it goes out. After thirty minutes, he reached in, hit the key, and she fired right off and purred like a kitten.
It's a pisser thought that he had to put all that money in it and maybe even for a fuel pump that he may not have needed. And the other thing is the mechanics he has taken it to could not figure it out and they were the ones that says he needs a fuel pump.
Of all the Chevy's I've ever owned, I never heard of this. I guess it works as far as someone stealing your vehicle because it shuts off the fuel to the engine. And some of the articles I looked at was the cars with the transponder key which he doesn't have. And the other thing he doesn't know is how it got into the security mode in the first place.
