Can anyone tell me how to bleed the high pressure fuel pump? I believe I run it out of fuel. I have changed the lift pump and I am geting fuel to the return line ,but no fuel to the injecters.

 

Welcome to DTR

What year truck do you have?

 

You indicated you changed the lift pump, what was the initial problem? My 03' keeps dying and the local Advance store read a code that was "fuel pump A circuit control low CODE:PO628. Was yours a similar problem or code for the pump change?

 

I had four codes po336 crankshaft position sensor A circuit range or performance problem. po253 injection pump metering control A low fuel injection pumpfuel valve open circuit. p1689 and 1688 don't know what those are. I'm sure it not good

 

I may hve done the reply wrong I am new at this. my code was po253 injection pump metering control A low fuel injection pump fuelvalve open circuit.

 

Yea I had the crankshaft position sensor code first & replaced it. Now I'm getting this PO628. I did find out that the same sensor is used for both the crank & cam.

 

I've got a scheduled appointment with the local dealership Monday if I cant fix it between now & then. If it is a pump circuit problem would that be covered under warranty on the Cummins 100,000 mile part or not??

 

Mines a 00 3500 with 142,00 its been a great truck until now I hope I don't have to replace the high pressure pump.

 

thats a good question. is it part of the drive train in there book?

 

OK, that may be part of the difference in the code #s but similar (kinda sorta). Mine has just turned over 90,000.

 

its a 00 3500 4x4 with 142,000 laramie pkg

 

I sure hope so...

 

What brand of lift pump did you get?
