What's that for???
1 set of keys for my harley are hidden so well, i cant find them.
LOL, that's my problem....I just leave mine in the windshield pouch where I can find it![/QUOTE]
my s-10 is 4.3 TBI (not the original engine)
i installed aftermarket mechanical guages for oil press, eng & trans temp.
fuel pump relay is closed by the eng oil pressure switch, so at the guage i have a pressure switch tied into the fuel pump relay.
at start up, theres no "immediate" oil pressure to close the relay, so i have a momentary push button under the steering column to bypass the switch and momentarily power up the realy to turn the fuel pump on.
more on the safety side, if the truck rolls, and i loose oil pressure, no power to the relay and the fuel pump cuts off, and kills the engine.
when i built the truck originally, i had one toggle switch to turn on the fuel pump and primary cooling fan,
i rolled the truck 2nd time out with it, and it stayed running laying nearly upside down.
by the time i realized it was still running, (i was checking on my passenger), the eng oil pressure pro light was on, and the guage was reading 0 psi.

that got me thinking back to my off road racing days, any vehicle that had an electric fuel pump was required to have a pressure switch that activated the fuel pump(s), bypass button allowed cold eng starts.
