    Help, 802a cranks but won't start. Possible injector pump / rack issue

    Next thing I would do is pull the other metering pump and try the same test to see if the rack is hanging up due to an issue with the other metering pump. It is advised to reinstall the first pump before you remove the 2nd, just so the rack stays in position, but honestly I have always taken all...

    MEP 805B discharging the batteries

    I would double check your charging system. If the machine will not stay running on its own you must not be getting enough amperage out of the charging system to keep the fuel pumps, solenoid, etc. running. Also sounds like possibly 1 bad battery, but I think you also have a charging issue. Maybe...

    MEP-803A, AUX fuel pump won't work

    I would definitely say the module as well. The issue is not that you only have 23.xV , the pump will definitely still run on 23V but if you put a load on that 23v line you will find it drops to probably around 6V, which will not run the pump. It's the module causing you to not have voltage once...

    803a not warming up

    I think maybe some additional cold weather testing might fit the bill here... The thermostat should do a decent job of maintaining engine coolant temp, within reason, but maybe the wind and air drawn in by the fan is contributing to cooling down the water separator and other fuel system...

    MEP004A keeps running at low RPM after it is shut off

    If you want to verify the fuel solenoid you can untie the safety wire ( assuming it's there ) that holds the lever on the side of the IP in the counter clockwise position. Shut the machine off and throw the lever to the right to manually shut off the IP. If that kills the machine immediately...

    Mep 802 A fuel gauge

    Definitely test your sending unit. A dead spot in the sender will also peg the gage all the way up. The dead spots can also be intermittent, so check closely. Make sure you disconnect the sense wire from that gage before testing it otherwise you will get an incorrect reading. I would just...

    803a not warming up

    Makes sense. At the temps you are talking about it looks like most of the common anti-gel additives ( including howes ) are questionable at best, despite their advertisements of -65F With Diesel 911 being a NO-GO at as little as -20F, which is right where you are at. I'm no diesel expert but...

    MEP-002A Cranks but won't start

    Although it's a little late now , but did you ever get to try bleeding the injectors by cracking the injector lines and cranking the engine? This would have also answered Guy's question above as well. Still no harm if you already pulled and sent the injectors since 9/10 times they at least need...

    803a not warming up

    Something still doesn't seem right. I can't believe the engine isn't producing enough BTU's to maintain combustion?? There's gotta be something else wrong. Once running the coolant temp shouldn't drop too much if the thermostat is working, and the machine should not smoke and shut down just...

    Mep806b challenges

    Holy Guacamole! $6ea. I would never have guessed... 5 years ago we closed up one of the manufacturing plants where I work and they let employees take ANYTHING that wasn't considered part of the building! I got an unbelieveable amount of stuff, everything from machine shop equipment, inspection /...

    Leak: Thoughts before degreasing and diagnose

    To get the crimp ends off just slit it down the side with a Dremel and cut-off wheel. Replace the line with 1/4" fuel / transmission cooler line and either use squeeze type clamps or regular hose clamps.

    Ambac M-50 Rebuild w/ pics (MEP-003A)

    Ah, you guys were typing faster than me! You got 2 replies in before I could type 1. Sounds like your check balls are not working correctly as well as clogged strainer. Clean everything up and reassemble and test, you should be fine. I have never seen a video, but they are so simple to take...

    Ambac M-50 Rebuild w/ pics (MEP-003A)

    I wouldn't worry about buying parts for the original pump. If you disassemble it and clean everything including the 2 check balls, plunger and strainer, etc. and it still doesn't work there is nothing else you can "replace". At that point your best bet is just purchase either an Airtex 24V pump...

    MEP-016B no start help please

    Excellent work! for fuel treatment you can really use just about anything available locally. Lots of guys also use PRI-D which is for me is a mail order item. Diesel 911 , Power Service Diesel supplement and Howes Diesel Treatment are all usually stocked locally as well as a hand full of other...

    It's not a problem to ask for help, we're all here to assist anyone we can. It sounds like maybe it's just a matter of becoming familiar with how the forum works. Every machine / model is different, so you have to keep an eye on the title of the post you are replying to to know which series...

    MEP-016B no start help please

    It comes apart all the way down to individual components. There is no info in the TM because it is a throw away part, but I had found it on you tube back when I needed it. Pay very close attention to the markings to align when you reassemble. Search Bosch PFR injection pump for detailed...
