i have a 1999 dodge cummins 24 valve. the truck is hard to start after sitting for a couple of hours. i installed a new lift pump from pennsicola deisel the upgraded version, also installed a new injection pump from pennsicola. still having the hard start issue after the truck sits for a couple of hours. I have been checking for leaks in the lines and haven't been able to locate any visible issues. the truck runs great after it is started. i have been driving the truck for two weeks now since installing the new pumps hoping if there was any air in the lines it would bleed itself out, but no luck. any help would be greatly appreciated.

 

Have you called Pennsicols diesel yet? I would call and ask. As for the reason im sure some of these guys can help ya out and

 

Is your fuel filter new? Does it prime up easy after you change it?

 

yes i tried calling pennsicola about the problem they said to check the fuel line from the tank to the lift pump for leaks. the fuel line looks great no sign of leaks, i also changed the fuel filter and it did prime up easy with no problems.

 

does it do this when the fuel tank is full?

 

By the "upgraded version", do you mean the in-tank pump?
Usually the fuel lines won't show leakage, but can allow air into the system.
Are you starting it properly? Turn the key on and wait for the WTS light to go out. That should also allow time for the lift pump to pressurize the system.
Also, are the grid heaters working? Do you see a draw on the voltmeter before starting and a fluctuation after starting?

 

 

Enjoy your stay...

 

any resolve on this?

 

i have had trucks where they were getting to much pressure on vp 44. i put a fass on one truck and had to change hot wire to power window. so that you could turn key on to prime pump but while you where cranking eng, pump wasnt on, then as soon as you released key pump would pump again. fass has this method for hard starting. something about vp 44 that is shutting (checking)
