Whats up all. Ive read several of the posts but couldnt find one that has the same issue as mine. My truck had sat for about a year and the engine and tranny were replaced. Once installed, it fired up and ran fine. Then I tried to start it later and it would try to fire, but wouldnt run. I unplugged the battery and the next day it fired up and ran fine. I had a hard time starting it again 8 miles later, but it ran and went about 100 yards and shut down again. Hasnt run since. I have verified that it is not getting fuel. The fuel pump works when the cover from the fuel pump relay is removed and operated manually. There is not 12V coming into the relay in the power box in the engine compartment. The check engine light turns on when you turn the key to on. What can I do to figure out if it is the computer or a wire issue, which seems to me it would be unlikely. Thanks for your thoughts.
