I have a Cavalier that will turn over fine but it just won't start. At first I thought it was just the ignition coil, but I discovered that there are three of them and I don't think that all 3 would go at the same time. I am thinking that it is the module, but I was wondering if there are any other possibilities that I could try before I spend the $300 on the part.
Do you
have the same problem?

Yes, I checked that. The motor turns over fine, but there is no spark. It was weird because it was running fine. I came home, and shut the car off, and it hasn't started since.

Hi, have you done any testing, did you check for spark at the plugs? Have you checked for codes? You should be able to check for codes, by using a jumper between the A&B terminals of the data link connector. Then turn the key till the dash lites come on, no further. The mil will start flashing, you count the flashes to get the codes.

I don't have a code reader. When you say use a jumper, do you mean I could just use a 12V test light between the A&B terminals

No, you can use a short piece of jumper wire, a paper clip might even work.

I gonna let Buddy talk to you, he was here first, I didn't see him when I first posted.

If you have an Orielly's in your area, they should have a module tester that will work. Call them first to have them look up the module, and then ask them if their tester will work on it.

You will have to take it off of the car. And I know it seems like a lot of work, but just take your time.

There's not much else to the system except for the crank sensor.

The good news is that they have a new module for only 80 bucks.

Not 300 like you were worried.
