I know of many people that have these issues and spend a ton of money on parts they dont need. Everyones first thought is fuel pump and have there car towed, But usually its a quick ten minute bandage until you can get a new switch.
The reason for the new fuel pump fixing it for awhile is that it reset itself when the pump was unplugged.
As I had to tow home because wouldnt start.
I have replaced starter new battery new alternater still wont start,and also starting really hard the motor has only 90,000 not bad for the year,Ive checked to make sure getting furel pump is working fine,checked spark on all plugs and each has spark. Do you folks have any suggestions where to go from here and what else I can test out?
Thank you troubled Pontiac owner
Also, when you post, please don't use ALL CAPS - it's hard to read and, on the internet, is considered the equivalent of shouting. If you re-post the issue you're having, perhaps others can offer you advice (within this forum, not by phone).

Like everyone else, I need new suggestions/hints/tips/tricks on what to do before sinking a ton of money into something that could very well be only needing that blasted security wire behind the dash cut ( we are trying that in two days when bf can come over). I've read article after article on this, and like I said, the security light is not flashing this time.
Thanks for any and all help.
I have a 93 / almost 94, OBD 2 wond hook up, anyway, ran great, started dieing by loss of spark, i replaced coil pack, again ran great, a road trip proved that, about 240 mi, died in intersection, ( SUX ) had shipped home, bought a new crank shaft posision sensor, not yet replaced, it will now start and run for a short period of time, then die again and wont restart for some time.
What are the chances it is in fact the crank sensor ??
Thanx in advance

Also you may have to smog it (depends on your state) or you can't sell it. Obviously it's not going to pass as is.
Someone should do a computer scan. I expect that the seller has tried to fix it, so he may know more than he's saying.
It's not too risky at $400. You could probably junk it for close to that or pawn it off on someone else.
Apparently, the computer recognizes a defective fuel pump and prevents the FPR from pulling it to energize it. Probably a safety feature so a bad pump does not overheat or spark while immersed in gasolene.
thanks kimber

Also you could have a fuel pressure regulator problem:
The fuel pressure regulator is a diaphragm-operated relief valve with fuel pump pressure on one side and manifold pressure on the other. The function of the fuel pressure regulator is to maintain the fuel pressure available to the fuel injectors at 3 times barometric pressure, adjusted for engine load. The fuel pressure regulator is mounted on the fuel rail and may be serviced separately.
If the fuel pressure is too low, poor performance and DTC P0171 could result. If the pressure is too high, excessive odor and/or DTC P0172 may result.
Refer to Fuel System Pressure Test.
