Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
I am sorry your having this problem
what is the fuel pressure reading key ON engine OFF with a fuel pressure gauge ?
if you pull out the 2 front O2 sensors will it still not go over 1100 rpms ?
will it ?
ok will it rev up with the MAF unplugged ?
is the MAF clean and nothing blocking the center of the MAF ?
are there any codes set at all ?
with 54 PSI key ON engine OFF that should be enough fuel pressure
egr would not stop it from going over 1100 rpm's
can you do a compression test on all 8 cylinders ?
i will be here for a while longer
i mean you tried the O2 sensors out and the fuel pressure is good
then either the compression is low or the MAF or MAP sensor are causing this issue
are there any throttle codes set ?
that compression should be fine for it to run
can you get it to rev up over 1100 rpm by adding carb cleaner down the throttle body ?
only cylinder 2 and 3 you mean ?
at the crank sensor with the key ON does one wire show 12 volts and does another wire show a good ground ?
it was doing this before you changed the crank sensor ?
ok at this point with a new crank sensor and good fuel pressure and compression good and just 2 cylinders firing if the grounds are all clean and tight on this engine i would have to say to try another computer next
you have just about eliminated everything else
it really is the only thing left
pick one up and have it programmed then relearn the theft system and see how it runs
