I have a 2004 Grand Am 4 Cylinder SE..

Asked by Marissa Jan 23, 2014 at 11:19 AM about the 2004 Pontiac Grand Am SE

Question type: Maintenance & Repair

My car wouldn't start about 2 weeks ago because I finally figured out it was a gas line and it was frozen, so I got it up and going and it worked good for a week, well now it's in my drive way and won't start.. it  cranks and cranks but will not fire, it's not my fuel pump that's been replaced and checked. Sometimes it'll run for a few seconds then it'll just die.. What could this be? I need my car!

Do a fuel pressure leakdown test. Find out the starting fuel pressure spec, the pump should create that amount of pressure with the key turned to the on position. Then watch the fuel pressure gauge for 10 minutes. It should not drop more than 1-3 PSI. If it does, check for fuel leaks, a bad fuel pressure regulator, or the pump itself.
