I have a 2003 Monte Carlo SS, and have run into a problem. I was driving to work, and it just died. Will crank, but no start. I had it towed to a dealership locally. They diagnosed a bad fuel pump. Had one put in, still no start. Said the ICM tested bad. Took them the one I had changed out about 6 months ago. Tested fine, still no start. Any ideas? Is this place just throwing darts at the problem? The last I heard from them they were checking the crank sensor. Could this FINALLY solve the problem? Any other suggestions I can pass on to them since they can't seem to figure it out would be helpful. Thanks!

 

My first thought would be a Crank Sensor..

 

Ok, here is the update. Dealer finally looked at the crank sensor and found a damaged wire. Replaced the wire, and now the car runs fine. Thanks for the help!
