Grant89, presently the truck is up and running. It seems that any time the lift has a low or dead battery issue with excessive overcranking it takes out the LPG driver. This time a coil blew backfeeding into the ECM and taking the ECM out. I have completely disassembled the wire harness and made sure all grounds are intack. Our people here will crank one to death just to find out its out of LPG --- go figure--- Thanks for the interested and throw out your thoughts--- I am a good listener Ray
