Car starts. Turn off. Try to start again and it dies after 2 seconds

[hevenz]

Ok- Sorry for the long post. Months ago i downshifted in to a gear i shouldnt have. Tranny goes boom and days later i take to the best DSM shop in Kansas. Tranny goes in for a rebuild from tre. I added a lsd, FMIC, Flash forward to today, I got a call from the shop, and was told that the car wouldnt start. He asked about any car alarms that might be doing this. Told him the car never had one. He said he would call back. He switched out the ecu with a know good one. Car starts. When it gets shut off and restarted it stays on for 2 seconds then dies. The shop said it checked all relays, all wiring, and is stumped. So he refers me to a Electrical car shop. And it cant get looked at till wed. Has this happend to anyone before? The electrical shop said it might still be the ecu because each ecu should be reflashed to each individual car. ( which i never heard of) This sucks... i havent driven my car since febuary! Well, i have no choice to wait... longer. But ias hoping to hear from fellow dsm'rs to see if anybody has had this problem before!

Have they checked for jumped timing?

I had a bad CAS that would let it start for 3 sec. then it cuts fuel and/or spark. If it was me I would try w/ a known good CAS .
