No start after fuel pump replacement
Replaced the mechanical fuel pump in my 95 7.3 today. Truck ran before but pump leaked and had loss of power. Put the new pump in and truck fired up after a few cranks. I keep the rpms at about 1500 for 5 minutes to get the air out of the system. Let the truck go to idle then it died. Hasn't restarted all afternoon. I'm very confused. I have plenty of fuel. It just won't fire at all. I have no idea what could have went wrong?

That actually isn't a definite rule. you can have a moving tach but no rpms actually being read.

If I had money to just **** away I'd replace a lot of things but the fuel pump drained my account. Just trying to get my truck up and runnin again so I can get back to work.

Well I looked and there's about 6-7 wires in a harness on the front of the motor. It splits to 2 sensors coolant temp sensor and cam sensor. Where the other wires go I have no idea.
