Everytime I turn the ignition key on my 94' Z28; the car just turn over but it won't fire. The 2nd or 3rd time I turn the key it starts up fine everytime.

I was told I may have a fuel relay switch problem?

Does this sound right? Where is it located? Is it called a fuel relay switch?

 

fuel pump relay is under the hoow in one of the fues boxes.
take it out and try to wiggle it. (sometimes ithas coroded contacts) as for the fuel pump. wait overnight...get in to start it but leave the door open. turn the key to ACC but dont start the car. do you HEARthe fuel pump prime/turn on for a couple seconds??? if not it could be the fuel pump going bad....

 

Blu, the only thing that comes on in ACC is the radio... When you take the key to ON, the fuel pump should come on.

 

Thanks for the quick response.

I doubt the fuel pump is going bad because I always hear it turn on. I have even turned the car to ON and leave it for 10 seconds to fully prime and it still doesn't like to start.

The guy who I bought it from (mechanic for Chevy) told me that the fuel relay switch is on the drivers side below the fuse panel. He pulled it up on his laptop in the shop.

I read a review from a Chevy expert at allexperts.com and someone explained the same problem. The problem in his case was "the check ball in the fuel pump is bad":

I want an easy fix...not one that is going to make me cry

 

You are never going to find the fuel pump relay with the direction you were given. LOL The fuel pump relay on the 94 cars is attached to the foot rest bracket (bump on floor) on the left side of the driver near thedoor hinge pillar. You need to lift up the floor carpeting to get to it.

Being that the car eventually starts up and runs OK, it indicates that there is nothing wrong with the fuel pump relay, because unlike earliercar generations the relay is the only path for power to the fuel pump. (Excluding the pump prime test connection)

IMO, the FI system is loosing pressure when the engine is off, and needs a few priming cycles to get the pressure back up. You can verify this by quickly turning the ignition key ON & Off several times without attempting to crank the engine. After the last ON-OFF cycle try to start the engine. If the engine now starts right up, it is a very good indication that the FI system is not holding pressure. You can also double check by doing a fuel pressure test.

Possible reasons are: Leaky fuel pump check valve, bad pressure regulator, leaky injector, or an actual fuel leak.
