1999 dodge ram 2500 5.9 cummins diesel.won't start.turns over thats it. put in a new intake fuel pump. still won't start.got fuel to the injectors sometimes.
Check the fuel pressure at the filter. Odds are the lift pump, located below the filter, is toast. Continual cranking of the motor with a bad LP wil cause the injector pump to heat up and burn out. Replace the LP and fuel filter. Bleed the system by cracking the inlet to the injector pump and bumping the enigine over so the LP will run. Once you have fuel at the injector pump, crack injectors 1,3,and 4. Crank the motor for no more 6 or 7 seconds at a time until it turns over. Give the pump time to cool for a couple of mintues between cranks. This process is easier with two people, one to crank and the other to watch for fuel and tighten the injectors once it starts. If the injector pump is fried at this point from cranking with no fuel, the motor should idle, but will stumble all over itself when the throttle is applied.
