Question about 2000 Pontiac Bonneville

1 Answer

I have a 2000 Pontiac Bonneville. I have been having trouble getting it to start, but usually after 3 tries, it will start. Sometimes it will shut off while I am driving it. The service garage has replaced the computer, ingition coil and the ignition module. None of these worked. Do you have any suggestions?

The next time the vehicle does not start you need to test fuel pressure. if you have none or very low pressure under 40psi on pressure gauge you more than likely have a faulty fuel pump or at least a fuel related problem. Based on this complaint I never would have replaced the above mentioned parts. Complete waste of money. When ever you have an extended crank issue always check fuel pressure first. More than likely it is taking a few cranks to build enough fuel pressure to start the vehicle. Watch this quick video and it will show you some basic testing for no start diagnostics. http://www.professionalfleet.com/videos/view/7-rough-run-stall-stumble-service-engine-light

2000 Pontiac Bonneville SSEi starts and immediately dies; will not run without foot constantly on gas pedal


Well pumping the pedal on a fuel injected car does nothing. If there are no trouble codes stored in the computer, look for excessive fuel from the injectors or the fuel pressure regulator. Or lack of air thru the idle air control valve.

have you replaced the spark plug wire? If so, have the coil checked. Usually it is a bad plug wire that makes it run poorly.

My 2000 Pontiac Bonneville wipers wont shut off and the handle is on the off position. what can that be?


if you look under the hood, locate the wiper motor. on the front are 3 torx head(star) screws holding a black cover abount 4' x 4'. once you unscrew those, look inside, that is your wiper module. very common for these to act this way. replace it. the dealer usually carries this in stock.

1993 Pontiac Bonneville


1. Air filter dirty
2. Bad engine ground connection.
3. Loose connection in the ignition system.
4. Faulty idle control system.
5. Faulty emissions or engine control system.
6. Fuel not reaching the injectors.

These are the 6 most common solutions. For yours, i would certainly be checking the engine ground cable, as your gauges are acting up too. Take it right off, clean the rust if there is any. Bend it back and forth every inch or so to see if there are any breaks or melted spots in it. Or, better yet, just throw it away and get a new one. Good luck, hope this helps.
