Simply put: I was driving andthe teg died. The check engine light didn't come on. I had some wiring diagrams and troubleshooting info and started checkinjg things. The failure of the check engine light indicated the ecu as faulty. I had a spare main relay and swopped it in, no change.

I swapped the ecu (spare I carry) and the check engine light came on... when it went out I tried cranking, but it goes out as soon as I do. Any ideas?

 

We dont' have TEG's on this site, but someone may be able to help.
