Question about 1999 Pontiac Grand Am GT

99 Grand Am 3.4 Won't start

We replaced the throttle positioning sensor in the car, then the plugs and wires and a few days later the car just shut off while i was driving down the road. Now the car won't start. We replaced the coil packs and module and still nothing. When it does start it runs really rough and backfires. Can you help?

if the throttle body cables are still attached and a bit rustic looking try some liquid wrench on then to get them moving freely and white lithium greese to keep them moving. always have white lithium greese and liquid wrench. wd-40 is not good because sure it removes water but it removes any lubrication you had prior set also and dries cables out.

First of all, a diagnostic wont tell them that there is arcing involved. I am thinking it is your crank sensor. It expands and retracts in different weather situations.It should make contact in all weather situations.

Check that the battery has full voltage (must have 12 volts or better and able to withstand a 200amp load for fifteen seconds and be able to snap back to full voltage immediately after test) and that connections are clean and tight. If you have replacement ends on the cables, make sure that there is no corrosion where the wire attaches to the end under the straps.

My 00 pontiac grand prix starts 3 seconds and shuts down


P1122 is a throttle position sensor code. P1629 is a theft deterrent system code. P1122 will set when the voltage signal from the throttle position sensor drops below 0.1 volts. Normally, the sensor should measure between 1 volt at idle and 4 volts at full throttle. A failed throttle position sensor could easily cause your problem.

As for the theft deterrent system code, with that code set, the car shouldn't start at all (if the code is active). With P1629, the engine computer should refuse to deliver fuel to the engine. This code can be stored for up to 40 warm up cycles before clearing itself, so unless it is currently active, there may not be any need to worry about it.

I would inspect the wiring and connectors leading to the throttle position sensor. If that wiring is good, I would replace the sensor and see where that got me. Give that a try and let us know how things go.

99 hyundai accent starts sometimes. not battery


ok when the check engine light comes on that usually indicates a engine malfunction...what you can do is go to your local autozone and they can do an OBDII test for free..my bet says it is the cam or crank sensor.. DO NOT SHUT THE CAR OFF AT AUTOZONE..LOL
