Also you said "other problems" what were these problems?? Does this truck have a seperate injector driver controller for the injector? This might be just on the older tier one and six cylinder trucks just wondered if this truck had one? Did you match up the old ecm numbers with the new one to make sure you received the right one?
What is your fuel pressure running at the vaporizor while its cranking? Did you check the last chance screen in the mixer...this is where the vapor hose comes into the mixer,is a small screen about the size if a nickel....
