This is one of my customers cars. Customer stated he was driving with no problem came out from a store and the truck wouldn't start. Had it towed to my shop. It cranks and won't start. There is no power to from the fuse box to the fuel pump, haven't checked spark yet. Did some research and said if there is no power to that fuse you have a bad pcm.

does the fuse have power for the first 2 seconds when you first turn the key on?does it have power when turning the starter?
does it have a spark?

There is a fuel pump code. It says there is a loss of communication to the fuel pump. Haven't checked spark because there is a fuel pump issue
