my 04 pontiac montana quit while driving down the road, I have spark, the fuel pump cycles on when I turn the key on but nothing, it just rolls over.

 

Optional Information:
2004 Pontiac Montana 3.4

Already Tried:
At first I thought I had no spark, I changed the crank sensor, cam sensor and the ign. control module, after that it did barely fire like once, then nothing again, I do have fire, I checked it with a testor.

Have you checked for any codes or is the check engine light on? Have you checked fuel pressure even though you can hear the pump run?

There are no codes, there had been some egr closed? code in the history. I havnt' checked for fuel pressure other than to check on the engine side of the fuel pump, I separated the line, the fuel sqirted out, not dripped.

You really need to check the fuel pressure as it may seem like enough but the system needs a minimum of 52-59 psi key on engine off. If out of spec suspect a faulty fuel pump and replace the fuel filter for added insurance to the pump.
