Pontiac grand prix 2004

Asked by MelissaS78 Nov 04, 2018 at 09:11 AM about the 2004 Pontiac Grand Prix GT2

Question type: Maintenance & Repair

Car was running fine after I put new fuel pump on
and then out of the blue it just wouldn't start.  It will
turn over but it will not start.  Is it not getting
enough fire to the fuel injector?

Make sure battery has a full charge and connections all good. If it cranks good but won't start, have a helper crank it while you check for spark at the plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse. Any applicable trouble codes? I can only help with testing. If your missing everything, have to look for rpm signal? I haven't looked at your wiring diagrams?
