    HMMWV injector pump bad or??

    You can run a hot wire to the top posts on the IP and see if you hear it clicking or not. If no clicks then that's the issue. You can also put a hose straight from the back of the IP to a jug of fuel and place it in the cab and turn it over and see if it sucks the fuel out. If it doesn't then...

    I had a local place in mesa Arizona rebuild this last one that I'm getting ready to install. My opinion only, but I'm not sure i would trust a $212 reman. This last rebuild just cost me $1000, for the rebuild of it.

    HMMWV injector pump bad or??

    It was definitely a bad IP... twice. The best I have been able to figure out is that the bio fuel that was in it when I bought it has burned up the IP not once but twice and am getting ready to put another one in. There's nothing else in the system that would make it go out like that. Make sure...

    HMMWV injector pump bad or??

    Thanks. That is my plan. Had my old pump rebuilt that I had sitting in the garage rebuilt this week and the guy that rebuilt this one thinks it's the biodiesel or vegetable oil mixture that the military was running that's still in the tank that seized it up. I'm still sending the other pump back...

    HMMWV injector pump bad or??

    So just to give an answer on all this, it's the NEW Injection pump that's bad on this thing again unbelievably. I ended up bypassing the entire fuel system with a clear hose from a 5 gallon fuel can straight to the IP inlet with the can sitting level and it should easily pull the fuel from that...

    HMMWV injector pump bad or??

    It has the KDS box on it. I bought a harness but didn't put it in because it looked like there were several ground wires hooked at multiple locations including the block and can so I thought they put one in but it's in the harness so now I'm thinking maybe it wasn't the one that was installed...

    HMMWV injector pump bad or??

    Yeah it's pumping fuel passed the filter like crazy. But now I'm lost, just pulled out 4 of the glow plugs and tested them old school with wires to the battery and all got glowing hot, BUT, tested the ohms and all are 1.6 to 1.8 instead of 1.1 or less?? These glow plugs only have about 3 hours...

    Ok, I appreciate it. I'll start from square 1 again and see what happens. Thanks

    HMMWV injector pump bad or??

    I broke my meter this weekend gotta get a new one. The light is coming on and going off about 8 to 10 seconds in but I know that's not always accurate that they're working. It's just that it's doing everything the same as before and I am now just badly wondering if the IP was actually bad before...

    HMMWV injector pump bad or??

    No I haven't. I pulled it off and cranked it to see if fuel was coming out of it in case the solenoid might have been bad but no on the clear line. I remember you ended up having cracked line or something on yours?

    HMMWV injector pump bad or??

    The other ends are under the intake. I could get a few off possibly but not all without taking it all apart. But this is the second time it's done this. It has always ran just fine once it's running.

    HMMWV injector pump bad or??

    Tried getting it to fire with WD40 and no luck either which throws me off too. Stuck a hair dryer in the intake to try to warm it up thinking maybe even that the glow plugs could be bad even though I changed them the same time as IP. Pulled off 7 of the injector lines this time and cranked for a...

    HMMWV injector pump bad or??

    Ok, so round two with this mess. I had a new IP put in and was running fine. Would start it every weekend and then skipped a weekend and it started acting like fuel was bleeding off. Last few weekends it's been getting harder and harder to start. Now it won't start period. Put a brand new...

    HMMWV injector pump bad or??

    From the manual fuel pump to the fuel filter? No, it should be shooting out of that line extremely fast. If it put that line in a water bottle and crank, it would fill it up in 5 to 8 seconds probably. Sounds like you might have gotten lucky duramax and maybe just have a cracked fuel line...

    HMMWV injector pump bad or??

    I found several places on the internet who will rebuild them, which is the cheaper way to go. Just make sure they're reputable and don't just slap new parts and done. I've chosen to buy a full rebuilt one from eastern and then have mine rebuilt as a back up when I can afford it since it seems...
