Question about 2002 Pontiac Grand Am
I looked at info for the 3.4L
I need more info, I don't know what testing you have done? When you first turn on the key, no crank, can you hear the fuel pump run for a couple seconds? Did you use a gage and check proper fuel pressure.
Don't forget the fuel injectors.
The diagram is fuel pump relay--3.4L engine.

Testimonial: "Actually I need the diagram for the pump. The pump does not run when you first turn the key on. What you gave me may work, if the wires going to the pump are the same color as when they leave the fuse block. This car actually has the 2.2 but I would guess the wiring would be the same either way...but again, that's just a guess. It runs if you squirt fuel down the throttle so I know I'm getting spark, ignition etc. I have power at the relay, it is open somewhere between. This car's kind of been a nightmare. The security system failed, he didn't have the money to go through the whole deal with replacing everything so I bypassed it with a resistor. But before I did that it had to be pushed into the building because it wouldn't start even if you did the "re-learn" trick. I don't recall hearing the fuel pump then either but assumed the security system killed it and the ignition. It appears it's got more than one issue going on at the same time, uncommon but it happens. If you have the diagram for the wires back at the tank, that would be wonderful. Thank you for replying, Wayne"
