1991 Chevy Cavalier Starting Problem

The ignition module and/or crankshaft position sensor seem to be common causes of temperature-related problems like this..

HEI or DIS module. Depending on if you have a 4 cylinder or a V6. Charles

Before you piss away all that money!

Try disconnecting the Coolant Temperature Sensor, if it is on the low side, it will send a cold signal to the computer. Flooding the car and making it stall after a few seconds, if it starts at all.

The 2.2 has a new type of injector on it, where the dwell time is almost like an on and off, rather than a timed injector.

My money is on the Coolant Temperature Sensor. I'm not ruling out the Module, or the crank position sensor. Which, by the way are a major pain in the balls to replace on a Cavalier. But I own a cavalier with a 2.2, and have fixed literally a hundred of them. It qualifies me to make the sensor statement. not that the others are inexperienced. But the other poster even said he had a 3.1.

It should be:

On or near the thermostat housing, I'm nowhere near mine. So I can't look to tell you. There is a two wire connector on the sensor, and I think one wire is yellow, with a red tracer?

Good luck!

It will hiccup if you run the car with the sensor disconnected all the time!

Disconnect the sensor, let the car run for five minutes or so, then you'll have an idea if that's the problem, shut it down, reattach the wire. If the car doesn't restart, you know for sure you've found your problem!

The one wire sensor, is more than likely a temp gauge or idiot light sensor, depending on which your car is equipped with.

Sorry to hear that:

I hope you don't junk the car for a $40.00 starter?

If so, where are you located, I'll buy it for what the salvage yard offers you if you aren't too far. As long as it's a two door?

I usually put V-8's in them and make them rear wheel drive, I just gave the third one I did to the customer, so he could finish it himself.
