Question about 1998 Pontiac Bonneville
My 93 bonneville sse was running fine until the other day when all at once it started missing when i gave it gas.It has gotton so bad the car will almost not start at all.When it does start its idle only,when i give it gas it dies.I hear the fuel pump running when you first cut the switch on.(it doesnt come on every time).I have also replaced the maf.Where is the relay??
Wait, first check the fuel pump, fuel filter and the ignition coils. If your fuel pump goes bad, it will start to heat up a lot and **** the voltage from your alternator, indirectly lower your battery voltage and can also be linked to coil failure. It will act up more when there is less than 1/4 gas in the tank. you can check the coils by getting a new or used coil and using the process of elimination (very rarely do all 3 go bad, if your car finally turns on and shakes so much that it feels as if will turn off but never does and your voltage goes way down then its at least 1 of your coils). The fuel filter should be changed if it hasn't been changed in the last year ( I recommend it for these cars as bad gas causes much damage) and check to see if fuel is getting to your engine. These cars also have fuel leaks around the front of the car especially where the 2 metal fuel lines meet under the front passenger side (the rubber connector wears out). If you're fuel pump is bad I then recommend changing your fuel pump relay as voltage and pressure will adjust. I hope this helps. Good luck
