What is your question?
We had our car into a shop 2 years ago, trying to get the abs light to go off, after spending just over 1900.00, had the cluster changed, and a lot of other parts, now the brake light also stays on, we can live with this. But, when the temperature falls below 40 degrees, the car won't start. Crank it a few times, go in the house for 10 to 15 minutes, come out and it will start. Summer is fine, early fall and late spring is fine, but winter, not so good. I have kept starting, it starts and dies, have to turn the key off, turn it back on, try again once I hear the fuel pump pressure up. The last mechanic we took this to put on a block heater thinking that would help, it didn't. Any suggestions?
How long has your 1999 Chevrolet Cavalier had this problem?
last two cold seasons
My wife's 99 Cavalier has his exact same problem. Tried replacing fuel pump, fuel filter, fuel regulator, battery, throttle position sensor - nothing. One of her co-workers suggested placing an electric heater in the cab ten minutes before starting (apparently she had a cavalier with same problem). As you can imagine, my response was "that's not gonna work. Sounds dumb". However, out of frustration, decided to give it a shot (after all, what can it hurt. Right?). IT WORKED LIKE A CHARM. Problem still exists, and I still don't know the cause, but in the winter, this is what we have to do every morning. Summer is fine. No need for the heater. And car runs great. In fact it's one of the most reliable cars we have ever owned. But when winter rolls around, out comes the heater and extension cord. Runs fine once it starts, and stays running for the rest of the day, starts right up. But initial start requires the electric heater. Any ideas? I'm still stumped. And in awe that her co-workers idea actually worked. Mike V. Albuquerque, NM
This sensor can fail in in a low ambient temperature condition and function properly when temperatures warm up..
Can’t edit so I’ll just have to add - the temperature sensor is responsible for fuel delivery adjustments according to ambient temps - if it is sending an incorrect reading to the elm - a no start condition will certainly occur.
