There's probably a relay that may control the fuel pump and the rst of the fuel system. I'd go to the local auto parts store and purchase a service manual, i believe it's only about twenty dollars. Good luck.

I have a 1985 Chevy C/30 pick-up with a 7.4L 454. Truck has been running fine and about a week ago I was driving down the freeway and the motor backfired and and lost power and eventually died. I stopped...


85 with TBI only needs 13lbs of fuel pressure. verify that the fuel filter is clean. there is no easy way to ck fuel pressure, special adapters are needed, I dont have info here at home but there should be a relay for the pump, on the firewall and the oil pressure switch also powers the pump. did you replace the pump trying to fix this problem or did you just mention it to help troubleshoot the problem? verify that the fuel pump wiring has a good ground, should have been a eyelet that bolted to the frame..when you initially turn the key on, you should hera the fuel pump power up for 2 seconds, then go off, after the engine starts, the power for the pump goes through the oil pressure switch.

My corvette doesnt want to start because theres no power going to the fuel pump fuse.


I am looking at alldata , the schematics for the fuel system. I see a fuse in the fuse block(10 amp) that comes from the fuel pump relay to the pump. I see a fuseable link (link H)that goes through a oil pressure sending unit. I would get a test light and test the oil pressure sending unit, the inline fuseable link and the relay. If still no power check the connection at the pump and then work backwards testing the harness.

I am thinking of buying this 1985 vette


Basics: 1. Do you have spark at the spark plugs?
2. Is fuel getting to the cylinders?
3. What are the compression readings? (only perform if spark is good, and fuel quality and quantity are good at end of injectors)

1985 corvette wont start


NEVER use either!! EVER! It burns very dry and can destroy a gas engine! Just give it a bit of gas down the intake.But keep the can away after each try! Far away! Not sure how you are getting 32v?? That can't be volts! Silly question, but is there fuel in the tank?? Have seen this before! It would be great to learn how this all started?? [or should i say stopped] lol Check the fuel line for a pin hole. It sounds like it is sucking air. Really need a bit more info. OK Frankster016

1985 conrvette


poss. is fuel pressure reg. problem. put a guage on the test port and check press. should be above 35psi. see if it stays running when you spray choke cleaner in the pcv valve steadily while starting. if the engine stays running after a few seconds of running on choke cleaner then probably a bad fuel pump relay cause the oil pressure switch will keep the pump on without the relay when it has good oil pressure.
let me know if ya can do this or if it helps.
