Hey all, I bought another non-running MEP-802a. It was robbed of many parts, so I've been going through it. I was told it ran and made power at one point, but engine quit starting one day. So far I've fixed the well nut, added the MOV, and dropped in some new batteries.
After changing fluids and all filters, I re-primed the fuel system and followed the TM to purge air from the injector lines. While cranking, the engine would pop a few times, but that was it. I checked the glow plugs and found the forward one was burnt out.
After replacing the glow plug, I stupidly neglected to double check the wiring on the other one and proceeded to burn up a second one because the rear glow plug was wired in a way that bypassed it and sent all 24 volts to the forward glow plug.
After replacing the forward glow plug again and rewiring both properly, things seem to be functioning better. At this point I cycled the plugs for 30 sec and cranked the engine again. It starts to fire and pick up rpm, but after a second or two, it falls on its face and quits popping, just blowing smoke.
I'm looking for what to check next. Should I be pulling the IPs or injectors to disassemble and clean them?
