Hey everyone, new to this forum thing and hope I get this across good enough to get an answer.

87 Camaro 5.0 TPI, my car is from the showroom drove it for 90K miles before I put it away, took it out a few years ago and would start and run it around, then let it sit for another year.

Now:
Won't start, yes with ether anything will start, but not run.
Checked the fuse on the fire wall near the battery its OK
Changed the relay. The one in the middle.
Turn the key on, I do not hear the pump run.
Put 12V to the "G" terminal. Pump Runs.
Is the oil pressure switch in series, it looks like it is from the diagram.
I jump the put 12V to the G terminal and turn the key and the pump shuts off.Can anyone think of what's next???

Inspect the wire from before the G terminal. Maybe there is a short before that fuse.

Also does your car have VATS or the bypass?

I see ya got it figured out (starting a thread)

Oil pressure switch is in parallel...this is not your problem

Put your hand on the Fuel Pump relay, reach inside and turn the key on and off..."feel for the "click".

All that said, with a bit of extended cranking, you should build enough oil pressure to run the pump.

Now with Pin G jumped...did you try to start the car?

I'd also get a fuel pressure gauge.

no VATS, old school…key with no chip, resister etc...
