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.

SOURCE: dodge cummins won't start, fuel reaching injector pump but no fuel coming out of injector pump.

You said you have fuel flowing from the inlet line of the injection pump? But not at the injector lines?

SOURCE: 1999 dodge ram 3500 cummings turbo diesel will not start.

Diesel engines fire on compression alone (usually 400psi).The Truck may have air trapped in the fuel system.When you perform any fuel system repair on a diesel it is going to take alot of cranking to get the air out. You can take the breather loose and shoot a VERY small amount of starter fluid in the intake and it should start. Do not use starting fluid much as it can damage the engine. Good Luck.

I need a fuel injector pump for an 03 dodge ram 2500 cummings diesel. i dont know how to find the part number so i can search for the part


Call any Dodge RAM dealer parts dept and they can give you the part number, have the VIN of the truck ready if they ask which they most likely will. The other source is my trusted online Auto Parts supplier, here is a link (at bottom of paragraph) they carry rebuilt pumps, call them if you are not sure which one you need. The pump are serviced by the VIN number of the truck so once again have it handy. http://www.rockauto.com/en/catalog/dodge,2003,ram+2500+pickup,5.9l+l6+diesel+turbocharged,1413470,fuel/air,diesel+fuel+injector+pump,6013

I have a mini excavator with a 3 cyl. isusu engine and am having a hell of a time getting it to start can u help


Have you primed the fuel system? If this eng has hydraulic injectors loosen the tube from the injector pump at the injector and crank untill fuel with no air bubbles comes out. Be careful as the fuel is under extremely high pressure. Do NOT unscrew the fitting completely.

Changed 2 glow plugs and car still wont start when cold.


I'm going to assume here that you did test the other glow plugs and they are good? How about the fuel filter? Have you checked to make absolutely sure that it is not sucking some air? You do not mention how many miles on this engine. Have you had a compression check done recently? How are the injectors doing? If you want to check them yourself, go get an extra long injection line from wrecking yard or new one and lets call this the "test line".Take out one injector at a time and re-attach it outside, in the open air where you can see the spray pattern. If you can't hook it back up to the same line, try using the test line in it's place. Either hook up a external starter button so you can crank the engine yourself or get some help. You should see a nice fine fog pattern if the injector & pump are good. If the spray is weak or off-center, log it, reinstall it back into engine and move on to the next one. If all injectors show a weak pattern suspect the pump and have it checked. If not, just trade in the bad injectors for rebuilt ones. Nothing wrong with rebuilts. I have used them all the time and much cheaper than new! (rebuilt pumps much cheaper than new as well)! Finally, have you tried to cold-start it with some battery help like a charger that has a start setting on it, or perhaps a buddy that can add a jump start to a running car. Sometimes a weak battery just can't do a good job of glow-plugging followed by spinning the engine over real good. Well, that's my 6 cents work! (more than 2 cents) Let me know how it goes?

Fuel pump to prim system don't run very long cummings engine how do i bleed the system after changeing fuel filters


get a 19mm end wrench and crack open the three injector lines you can get to then have someone turning the truck over and it will start pumping air out of the open injector lines start closing the lines up as you see fuel start coming out it will run a little rough for a few seconds until the truck computer resets and then should be just fine.

this sounds like the high pressure oil pump ( HPOP ) is weak. The HPOP is what fires your injectors. After it starts its building pressure..
