Pontiac Problems? Ask a Mechanic for Answers ASAP
Hi Im David, thanks for visiting the site, does the engine crank at all?
are you getting rpms while cranking?
its not even jumping?
ok. and when you turn the key on you cant hear the fuel pump running for a couple of seconds?
well i would say thats your problem. youve replaced the pump already?
did you bother to make sure the pumps connector was getting power to it before replacing it?
your fuel pump not running has nothing to do wit the crank sensor
are you using a noid light?
check the highlighted fuse
the fuse on the attachment i sent
check the crank sensor voltage, ground and signal.
no voltage? because the signal come FROM the crank sensor. you have to connect the connector and backprobe it while cranking
correct. the engine needs to be rotating
have you rechecked it with the engine cranking?
no signal from crank sensor? = bad crank sensor
hows it going?
the pcm isnt communicating?
is it ecen powering up?
no, is the scan tool powering up?
I am going to open this up to others. I havent anymore ideas.
