Cummins won't start when hot
The truck runs great and starts perfect when cool, but run it for a few minutes and it won't start once I shut it down.
I have replaced 2 lift pumps, 2 injector pumps, MAP sensor, and fuel tank pick up and filter, the only thing accomplished is messing up the fuel guage. Now I run out of fuel at a 1/2 tank.
A match and 20 gallons of gas are starting to sound good and cheaper.

Hard hot starts are the classic 2nd step of the vp44 - first step stock lift pump fails then without pressure guage - the injector pump vp44 starts hard starting then soon wont start at all. Once you put on guage get an airdog or fass and you will be a happy man. BTW if you need to change out the vp44 (you will) I have the tool to remove it and will loan it too you if you promise to return it. It is really kinda fun to do but can be stressful too. Also the screen on the fuel tank pickup bottom is really restrictive - engineer something better- I used a much larger heavier duty screen after the aftermarket lift pump install.
