The truck was a hard cold start for several weeks but would start if left hook to block heater
Then one morning it started ran 10 min in drive way and died
I have replaced the glow plugs the mechanical fuel pump the injectors and the IP still will not start help thx

 

Could be sucking air between the lift pump and tank or inside the tank. How much fuel is in it? Have you checked for fuel at the Schraeder valve while cranking? Did you bleed it?

 

disconnect one of the big wires on the gp relay preferably the ones going to the gps this will kill the gps then use starting fluid.. if it wont run..you broke it...

 

its prolly a problem with GP system, if it starts and runs then look into the gp system read the stickys,,, and check the block heater it may have failed also.. if it runs, its not the fuel system, its the gps, or block heater with out one of those, it will not start, with out using ether.

 

Glow plugs and. Block heater wont make it shut off after running for 10 minutes.

 

Today I put electronic fuel pump on and put hose into can of diesel truck start and ran so I am suck air from some where between tanks and motor check lines looked ok do u think it could be the fuel tank selctor

The bottom part of the pickup tube in the tank is known to fall of causing you to run out at 1/4-1/3 tank. How much fuel is in it?

 

^^^this^^^
i bet you are simply out of fuel.
i never ever let my truck fuel gauge get below 1/2 tank after it ran out at 1/4 tank about 10 years ago.
when i replace the cab i am also going to replace the tanks and pickups.

 

How are you getting the fuel gauge to work?

 

The truck has over 3/4 of a tank it is empty at 1/4 of tank on the front the rear tank has not work in over a year but it is nearly full.
