Hello members I am new here and would like to have some help. I have a 2003 dodge cummins have owned since new it now has 165,000 miles. It has come up with a problem where it don't like to start. I have checked all the wires fuses to the fuel grid all seems to be okay. When I turn the key on I think I use to hear a pump start during the fuel grid warm up, I don't seem to hear that any longer. I think I have a lift pump bad how can I know from here? Any help would be appreciated thanks again Wild Bill

 

Wild bill is kind of a trademarked name around here Lol anyway
You can install a fuel pressure gauge on the pillar to see what your fuel pressure is. It should be running of the key is on.
While you are at it, might as well do boost and Pryo as well.
Also. It is an air heater grid. Not fuel
