Ok, Replace the fuel pump a week ago and it worked fine. Then the starter didn't work so we replaced that. It started up and ran fine the first time. Turned it off and tried it again. Now it starts right up but won't stay running after a few seconds. Replaced the relays. No change. He's pulling the steering wheel off now to see if it's a broken wire. Tried all three of the keys we have. No change.

If wiggling the wires cured the code, then one of the wires is broken inside the insulation. Pull on each wire one at a time. look for the colored insulation to stretch, this will be the broken wire. For the other car that wont rev up, this is a common when the catalytic concverter is plugged up. This will also cause MAF codes, and in turn, TRAC OFF light.

If you replaced the fuel pump then there is a possibility that during the job then some debris from the tank and/or filter got loose somewhere into the fuel system and is in your lines. It could even be a very tiny speck of gasket material, old or new.

Possibly a weak fuel pump, idle air control valve, vacuum leaks, or loose or damaged wiring in the ignition system. Check for vacuum leaks first. That's the only one that won't cost anything. Make sure all intake bolts are tight, and all hoses are connected properly and in good condition.

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!

There are a few other things taht could be causing fuel starvation. First of all, did you pull the injectors and clean out the individual filters? There are small, conical screens inside the top of each injector, and they could be clogged. Second, There could be some carbon build-up on the intake valves, which would act like a sponge for the fuel after initial start-up. A can of BG44K fuel system cleaner from NAPA will get rid of that. If it is neither of these, the fuel pressure regulator could be leaking. Other than this, the car would need to be diagnosed by a shop before action is taken. I hope this helps you!
Testimonial: "I ended up taking the car to a local shop for diagnosis. It turns out that the fuel pump is week and not supplying enough pressure to the motor. "
