    MEP-831a will not start.

    Ok, Its been a minute, fixed the bad wiring and got the unit cranking, no start. Had already replaced the pump pre-filter & racor filter, pumped out the tank and re-filled with fresh fuel. Then confirmed fuel up through the injector pump by cracking the fuel line nut on the injector...

    MEP 831 FAQ for owners or potential buyers

    If you are running it in or near your house, you can run the ground to a clamp on the main water line coming out of the ground, as long as it is copper. If not sure, consult an electrician. :cool:

    MEP-831a will not start.

    OK, this was difficult, but not as bad as expected. First, the parts and tool for P7 & J7 are available from at least 2 online vendors as far as I know. I did research on "Mouser electronics" who carries parts and also has good technical drawings. I looks like they carry every piece of...

    MEP-831a will not start.

    Thanks to Kloppk and everyone on this thread. Went to do a periodic test run of the 831A and no joy, no pump noise and could not even do a manual start... Followed the above mentioned TM's and schematics, had good 25vdc at K2A1 & K13A1 but flakey voltage in the control panel on S1, then on...

    Throwing money down the CUCV hole

    I bet Pacifica CA would be a close runner-up. That ever-present salt fog comes in every night and does it's silent damage...

    m1009 motor mounts

    Hey there, I installed a fluid-damper harmonic balancer and that helped a lot with vibrations, even with the heavy-dity offroad designs motor mounts. Good luck.

    Poll - Who has done the Doghead Relay Conversion

    Yes! I put it off as a "Nice to do" thing until the starter gut stuck in "run" after filling up at a gas station & fried the fusible links. Duh-ÓH!

    Are you sure? They had a bracket for the steering box, not the pump last I looked, 2 months ago.

    Power steering bracket

    Impressive damage Kentucky! These pumps must see a LOT of torque. What kind of welder did you use, stick or mig?

    Power steering bracket

    Darn, had found a similar stud that fits from a humvee listing, but lost the NSN#! Totally Stainless will fab one up, its a #10 metric, 15mm hex nut. If I ever get access to a scanner, I'll post a drawing of it.

    Power steering bracket

    Power steering pump cradle...

    Thanks WH, Dealers were a no go around around here. (SF Bay Area) Since this seems to be a problem item, I'm looking into changing over to a type 2 pump and remote reservoir & filter setup like the performance boys do. I hate having the filler cap down there anyway. I'll post my findings re...
