Ignition Control Module?

[Darkshot38]

About 6 months ago, I was having problems where my 2001 Grand Am 3.4 would start, i would drive down the road, only to have it die on the side of the road. Before stalling the car would jerk really bad, almost like it doesn't have any gas(but it does). I took it to my local gm dealer, and they replaced the camshaft position sensor, and they replaced it. That fixed it for a day or so, but then it died again, so i took it back and they replaced the ignition control module. My car worked for a couple months then now, just decided to start jerking really bad as i went to excel at a green light, my car didn't die, and i got it home and preformed a couple tests, and i found that the Ignition control module is getting 12V and Ground is getting 12V from the battery. I went to test the camshaft position sensor (required 2 people but I only had me so i couldn't) However I was able to test to see if there was resistance, which there was (went off the charts when on 1K). I think the issue is my Ignition control module, but im not positive, and advice would be greatly appreciated.

do you have a check engine light on? have you read this link?

No, I don't have a check engine light. And that link is actually the exact tests that I did to check everything. The only thing I was concerned about is that my car runs, and those tests were for a no start condition.

How many miles since you changed the fuel filter?

Probably only about 1000km or so, cause I replaced it when the problem started along with the fuel pump.

I went back to your statement about the crank position sensor and you said it went off the scale at the 1k setting. The article says you are supposed to have only 500 to 900 Ohms not more than 1k!

So an over reading like that could mean that the crank position sensor is the problem, not the ICM?

 

[melsg5]

Thats the way I read it. You are supposed to have 500 to 900 Ohms and you state it went off the scale which means you have an open circuit. So either the sensor is bad or the harness has a broken wire.
