My truck was running great until a few days ago when it started to miss. I thought it was a hole in the piston because the pump was turned WAY up from the previous owner and i pulled the head, everything looked good so i put it back together and then though it could be a bad injection pump .. Logical right ? I looked through the service manual and the symptoms matched ... rough idle, missing under load or heavy throttle, lacking power .... Sooo I replaced the pump and CAN NOT get the engine to start . I try to prime the injector lines and can not seem to get them to prime. I cracked lines 1 3 and 4 but no matter how long i pump the lift pump and turn the engine over I cant seem to get it to fire ... Long story short I cant get the engine to prime and fire. ANY help would be GREATLY Appreciated

 

It sounds like your lift pump went out. Are you getting any fuel out of the injector lines when you try and prime the fuel system?

 

I made sure that there were no air bubbles in the low pressure line coming out of the fuel filter. I then cracked 134 and pumped until fuel was coming out of 4. I turn the engine over and over but all i keep getting is more bubbles out if the injector lines ,,, I called the company and they are supposed to be calling me back with a way to trouble shoot it and or correct the air leak .... And to rule out a bad lift pump i am getting a Carter rotary fuel lift pump that supplies 75 gph and 10 psi

 

Hmmm, ok. I hope you get this issue fixed.
