I have a 2007 pontiac Grand Prix base model v6. I have 60lbs of fuel pressure and I have spark but it will crank but wont start what do you think it is and I have have changed my crank sensor and the cam position sensor too and still nothing
What is the mileage please?
Run a scan to see what codes it throws. Most large auto parts chain stores will do this for free.
Also see FAQ section.
No codes this why I’m having trouble
I assume you got the codes for cam shaft and crank shaft position sensor. In this case, the timing of your engine might be off and if it is too far off, then you get those codes and the engine might not start.
So it doesn't fire at all?
Maybe a blown EFI fuse?
I have checked and double checked and triple check all my fuses and I checked all my relays too and I check to the the fuel injector plug with an noid light test and it fine there too
check:
ignition timing with a light. could be faulty position sensors or a failed ECM
cylinder compression
plugged catalytic converter
