Lesabre wont start

I have posted a few times on this and tried a lot of different things. Here is where Im at now. I replaced the starter and battery, cranks great now. Right after I replaced it, the car fired up and ran great, ide was good and acceleration was good, ran great for something that was sitting for a few months. After it ran for 20 min or so, I turned off the car, went to restart it after a few minutes, now Im back to where it was, no spark. Heres what has been replaced: New crank sensor, starter, battery, O2 sensor, ECM, ICM (both ECM and ICM are tested and work on another car) Right now, it seems to me like a heat issue, seems once the engine is warm, it doesnt want to spark. I let the car sit a few hours and tried again, wont start. Ill check in the morning after it completly cools. Any one have an idea?

Re: Lesabre wont start

forgot to mention something, I replaced the mass airflow sensor about 2 years ago because of a problem with it stalling, is it possible that the MAF could be bad? I might still have the old one somewhere.

Sounds like your "ignition module" needs to be replaced. which explains the reason that you arent getting a spark. Good luck!
