Pontiac Problems? Ask a Mechanic for Answers ASAP
can you keep it running working the gas pedal ?
if not can you keep it running spraying carb cleaner or starting fluid into the throttle body butter fly ?
usually these issues are low fuel pressure issues
see if you can keep it running on starting fluid to keep it from dying if you can then either the fuel filter is plugged or the fuel pumps are usually bad causing this issue
ok then lets see if adding fuel will keep it running
and at least narrow this down to a fuel issue or not
it could be but usually adding fuel would compensate enough for a bad MAP reading
lets see if any other experts have any ideas
hang on another expert will reply back to you
Hi my name is ***** ***** I will be happy to assist with this here.If at any time you feel I cannot help let me know.
Is or has the check engine light come on with this issue at all here or have you had the fault codes checked at all?
Let me know so we can continue,thanks Pete.
O.k.,if this model uses the mass air flow sensor (I believe it does but my info shows two options) with the key off unplug the mass air flow sensor connector and then turn on the key and see if it starts then and let me know.
O.k.,let me know if this does anything.
Can you test one one or more cylinders to see if spark is cutting out when this issue occurs or right before the engine stalls out and let me know?
