So the other day my truck would not start. When I turned on the key, the WTS light did not come on, then it would crank and crank and not fire. I opened three injector lines, but no fuel was coming out of them as I cranked. I finally used some starting fluid to get it running. Two of the lines still did not have any fuel coming out of them and the truck was running rough. I closed all the lines, reved the engine up and it finally started firing on all six. I was able to drive it, even shut it off and restart it, but then a few days later when I tried to start it it would just crank with not fire. I checked the voltage going into the VP44 and I do have voltage in what I think is the correct pin. I am not getting any error codes, but am wondering if it might be the injection pump that is bad and not the electronics? the reason for this is the fact that when I opened the fuel lines, even when running two of the lines did not have fuel squirting out of them. Any thoughts of other things to check on before I replace the injection pump. Also, I have taken out the auto trans and replaced it with a 5 speed, do I still need to use the S.O. injection pump? I am not sure if I will gain anything as I do have 75 hp injectors, so it may be just as simple to stay with what I have?
