no start

[John_Conrad]

1994 Pontiac Sunbird 2.0 L(4cylinder)

Battery good, starter good, cranks but no start.

I do not hear the fuel pump energize and am looking for fuel pump relay or if there is a fuse for this.

I have located 3 relays in the engine compartment on the passenger side behind the strut tower, but not sure which is the fuel pump relay(front, middle, or rear one ?)

Also is there a fuse for this?

Hook a fuel pressure tester to the Schrader valve and you should know pretty quick, if nothing else you can lay a rag over it and use a screw driver to see if there is any pressure at the rail. I can't speak to this with certainty, but the relays are usually the same could just move them all around and see if anything changes.

GM had lots of issues with fuel pumps in early 1990s.

this is not one of them, it is the original fuel pump in the car and has well over 200,000 miles(i'll get the exact mileage later)

are there any fuses to check on this?

I can't get the images to load at work but according to the Chilton manual there is a 10amp fuse for the fuel pump and its fuse #1 in the panel of 16 fuses.

Another quick and dirty way is to spray some starter fluid into the throttle body while cranking. If the engine fires up, you know you have a fuel delivery problem.

I am sure there are Pontiac forum that may have more expert owners hanging out there.
