Problem Description and Possible Solution
If the engine is difficult to start or cranks but does not start, it can be caused by a leak in the return side of the fuel system. This type of leak can allow air to enter the injection pump resulting in starting issues. A rubber hose on the back of the injection pump, connecting the pump to the steel hard line, that can be the source of this type of leak.

I drove it last night stared good and ran good got home then went out to start it this morg and would not start but i can hear the pump working and it turns over just wont start.
Engine turns over but won't fire. Have had no previous problems starting this truck has always started right away.
drove it turned it off would not restart just cranks
After starting and running my '07 Dodge 5.9l diesel it will not start again till engine is completely cooled down. Dodge by as not fixed and every time I take it in they remove supposed faulty sensors and still the same problem. Will crank but won't turn over, average wait time now 4 hours. I need help. Is this a cp3 module corruption, had a fuel lkeak right before this started. Put in high pressure fuel line and a new hard #4 fuel line just a few months back. I drive for a living and it is getting worse.
Engine turns over fine but wont fire
1995 5.9 / truck starts and runs fine when engine is cold. Once warm the engine stall abruptly and will not start until completely cool once again. The condition is worsening - as now it only takes 2-3 minutes at idle before shut down. Changed coil, cap & rotor, fuel pump, heat sensors, and checked all fuses. I'm out of all ideas...any suggestions?
Truck will not start when cold unless given a shot of starting fluid. Replaced fuel pump in tank. Still have the same problem.
Intermittenly....the engine will crank fine...but not start.
I drove my truck around town for a bit. Pulled into my driveway at home and shut the engine off. Came out 15 minutes later and it would crank but not start. Changed the fuel filter, insured that I had fuel coming from the filter to the injector pump, but did not have fuel coming out of the injector pump. Had it towed to a dealer where it sat for over a week to be worked on. In less than an hour after the mechanic started working on it he said it was done. I asked him what was wrong. He said he checked the fuel injectors first. Then he performed a "float test" on it. After completing the float test it started. When I went into pick up the truck, the mechanic was gone to lunch. But I feel the problem was not resolved. Occasionally I have a puddle of diesel fuel under the engine compartment of my truck. Tried chasing the fuel lines to see if one was leaking, but have not located it yet. I'm afraid to pull my 5th wheel trailer with it for fear of a breakdown.

Truck runs fine, plenty of power, no symptoms, then it becomes harder to start. Each successive start requires more turns of the engine, then finally it won' start after twenty or so revolutions. Let the truck sit for two days and it started after about 10 turns. Took it to the local diesel shop and had one injector replaced. Truck ran fine for about a month, then started the hard start business again. About the fourth start after hard starting began again, it fails to start. A second diesel shop says it is the injectors. I'm not convinced. Help!
1999 2500 24v-fires up, runs for a couple of seconds. Dies and then just turns over and over and over. Eventually end up having to hook up jumper cables and keep trying. It'll start to hit. Then hit again hit hithithit fire and stay running. It does bubble and suck/leak fuel around the two wires to the fuel heater.
Spins over longer before starting runs good
Truck won't start cranks doesn't seem to be getting fuel pretty sure I can hear fuel pump
Truck cranks won't start sprayed with either and it fires fuel pump pulses it's a 6.2 diesel king cab
After replacement of the lift (transfer) pump AND the VP44 main pump, after about 60 miles I noticed and smelled diesel dripping onto the ground right under the driver's seat. The mechanic said that the rubber fuel return line had failed where it goes thru/across a bracket.
Both myself and the mechanic had noticed a serious lack of power/snap" while driving...I pick up the truck this afternoon.. will see if the power is back to where is used to be!!
Truck will not start after sitting over night unless it is plugged in I pulled all connector tubes there seating surface looked great injectors are fully seated the connector tubes where snug but not torqued I torqued them all after reinstall to 44 Ft/Ibs and notice better throttle response and acceleration but it still wouldn't start the next morning just cranks.
Starts cold but when engine is warm you must crank a long time before it will start.
Lift pump suction screen plugged with fine fuss like wool.
Won't start after 4 hrs after turn of the engine I have to plug the engine all night to start the engine after 2 min of cranking
