I obtained a MEP-005 genset earlier this year. I had it running for a couple of hours back in June before it stopped running, and haven't been back to it since, until this week.
I have replaced both fuel filters, removed, cleaned and replaced the fuel strainer, given it an oil change with new filter, and drained a couple quarts of fuel from the tank to check for water. After replacing the strainer and filters I primed the system and checked for fuel coming into the injector pump.
At this point everything looks good.
I can turn on the battle short and run switch and I hear a clicking like a fuel pump running. I let that run until the clicks pretty much stop. I then turn off the battle short and the run switch. Then I press the run switch up to start and the engine starts and can build oil pressure, but then it just quits, like it's either out of fuel or some other interlock is tripping.
Yes, I'm holding the start switch until I get oil pressure.
I'm at a loss to understand what might be causing it to not stay running. Oil pressure builds and the oil pressure warning light goes out. All other lamps are functioning (tested) and nothing is coming on once started.
My fuel gauge appears to not be working, as I have nearly a full tank of diesel. I checked the sending unit wire, tried grounding it but the gauge doesn't move; I think the gauge may be shot, and since the engine starts, it would seem it's not due to low fuel.
Is there a good way to check the output of the fuel injection pump without making a huge mess?
Do I need to remove and clean the injectors?
What other interlocks are there that I should check?
Any pointers would be helpful.
Thank you,
Asa Jay
