Hey guys I have a 2006 dodge 3500 5.9 Cummins. It will start up good first start in the morning & run as long as you would like. Runs great, Never hesitate or miss fire. But don’t shut it off. If you do it will not start back up unless you spray brake cleaner in the air filter. Fuel pressure 10-15 psi. rail pressure 8,000-9,000 psi at idle. 20,000-25,000 wot.... it has a new fuel pump (in tank), 3 new injectors, new prv, new fuel shut off actuator on the back of cp3.... what should I checkout???
