1995 Pontiac Bonneville Fuel Problem?

Hello,

Does it feel like that from start up or does it drive fine for a while before acting up? If it drives fine for a while before acting up it could be the fuel filter.

My experience with Crank Sensor is that when they heat up the engine just dies. And if you let it cool down it will drive fine till it heats up again.

One question. Is your Check Engine Light On? If so and you can go by your local auto zone or parts store and have them pull codes for you and post them here.

.

OK, lets see about pulling the codes.....

Here's how.....

To extract a trouble from the computer for diagnostic purposes, the Assembly Line Communication Link (ALDL) connector is used.

Ground terminals A and B with the ignition "ON" and engine not running. The system will enter the diagnostic mode. In this mode, the computer will display a 12, three consecutive times, by flashing the "CHECK ENGINE", "SERVICE ENGINE SOON" or "MALFUNCTION INDICATOR LAMP" or light. A 12 consists of one flash, a short pause, then two flashes in rapid succession.

After 12 is displayed, any stored trouble s will be displayed by flashing the "CHECK ENGINE", "SERVICE ENGINE SOON" or "MALFUNCTION INDICATOR LAMP" light. All s are displayed 3 times each then a 12 will repeat. In the diagnostic mode, the computer will also energize all computer controlled relays and solenoids.

The ALDL diagnostic connector is located in the passenger compartment under dash.

Here are some codes...

13 Open Oxygen Sensor Circuit
14 Coolant Temperature Sensor (High Temp Indicated)
15 Coolant Temperature Sensor (Low Temp Indicated)

Ok, if the engine light is faulty then it is possible there are codes, and pulling the codes can pinpoint the exact problem.

When was the last time you changed the fuel filter? If it has been a while and you want to change it and see what happens, I believe it is located under the car either up near the driver wheel or near the gas tank. it looks like this......
