'94 Bonneville Intermittent Stall Issues
I bought a 1994 Bonneville last November, in the past year I have continual problems with stalling, in cruising situations (65mph) and after, the car will not start, and then bingo, it comes to life again.
I have had the fuel pump, fuel tank, starter module, sensors replaced, as well the entire tumbler and ignition replaced, and then they told me it was a wire. I drove it off the lot, hit the highway and BINGO! It started stuttering, and the warning bell came on. Any advice from anyone, I dont want to buy a new car till spring, and, I noticed this intermittent stalling issue seems to be an overall Bonneville/Pontiac thing (my grand prix did the same thing). Thanks. Syyd

Re: '94 Bonneville Intermittent Stall Issues
Most important and hardest part of intermittant problems is duplicating the complaint and narrowing down what system is causing the problem.
Read some of my replies on other posts about stalls and no-starts......(I need to have some stock replies handy instead of typing the same thing over and over again)

Re: '94 Bonneville Intermittent Stall Issues
I had a problem like this and fixed everything we could think of. It turned out to be a melted wire harness under the carpet by the driver's door. Direct saudered the wires and haven't had a probelm in 6 mos. (cross them fingers)

Re: '94 Bonneville Intermittent Stall Issues
There are ground wires that are all connected together at the drivers door sill. Pull the carpet back (right at the door) and you will see a black connector with about 8 black wires going to it. This is the common tie that hooks all the grounds to a main ground wire. There is a metal tab in that connector that links all the wires together. Pull off the black cover, remove the metal tab, clean all corrosion from this metal tab, re-install and your problem is cured. There is another common ground like this on the passenger side, but the drivers side is where the fuel pump ground links in. This is usually the problem.
