Sounds to me that you've got the gm fuel pump (blues) problem there was a recall on this a few years back ck wth dealer to see if yours is still covered by this (save $$)

ck valve on pump sticks open over time fuel flows back to tank , a quick test of cycling key Off/on/wait 3 seconds several times before cold start will confirm this (this reprimes pump) but sadly this problem is progressive eventually pump will fail all the way resulting in no start at all

Sounds like you are loosing fuel pressure overnight. Could be a fuel pump problem, or a leaking injector.

SOURCE: Surging

My wifes 1999 Sunfire has had problems cutting out and surging , spent 700.00 at local GM dealer still no results. I read somewhere on the web try to changing the Throttle Position Sensor. Changing the TPS has worked both times to fix the problem, for some reason the TPS failure will not send a code. We have had the car since 2000 and the chinging of the TPS has solved the problems bothy times. The TPS at NAPA in Canada is 74.00 in the US most likely cheaper, try this first based on my experience, GM will not help all they do is read codes.

SOURCE: running rough, no power misfiring

i had that problem once. when i got under half a tank of gas in the tank. What i did was i dumped one bottle of gas line deicer in the tank and i have never had it agian. you may have some water in the tank. from condasation or i have a stong feeling i got my water from the gas station. i was using the same station all the time. so i tryed another gas station and so far no more rough idleing which was caused by the water i think and i am getting better fuel milage to. i hope this helps.

SOURCE: I have a 1994 Pontiac Bonneville SSE.. won't start

It sounds like you have a short somewhere that is draining the battery...this type of thing is usually caused by a faulty voltage regulator. I recommend taking the alternator to an autoparts store to have it tested...don't be surprised if the alternator tests good; a faulty voltage regulator can and will drain a battery in a matter of hours. I am including a link where you can order a voltage regulator for your Bonneville or, while you are at the autoparts store, you can buy one there. The link will help you to see what the voltage regulator looks like so you can identify it in your engine compartment. Hope this helps, good luck!

My 1985 grand Marquis won't start I can pour gas

Take the gas filter off. Should be located near the front of the carbeurator, take off the air cleaner and look for it, it takes 2 wrenches to take it off, a little gas may spill out but not much and replace it, however there is a strong possibility that he gas pump is out if the filter is fine. Hope this helps

My jeep cheroke 1998 4.0

This one sounds like a faulty throttle position sensor. If the computer has generated codes to indicate this, P0122 or P0123, start with a visual inspection of the wiring and connectors at the TPS which is located on the throttle body. Disconnect the wiring connector and look for any damage to the terminals. Reconnect the the wiring connector and use a scan tool to verify that the voltage changes smoothly from 1.0 V at closed throttle to 4.5 V at wide open throttle. If the voltage change is erratic or jumpy, try replacing the throttle position sensor. Sometimes, just disconnecting and reconnecting the wiring can solve a poor connection.
