Mep-002a, Starting problems

[RichL]

Picked up two 002a's on trailer. Both with just a couple hour's on them. New Fuel, Oil, and filters installed. Getting fuel to pump, but don't get any fuel out of injector lines. Not sure what it's called, but the device that retracts when you hit the starter seems to be working fine. the arm on the side of injection pump is a little stiff. Could the injector pump be bad with only two hours on it?

The short answer is yes, if moisture got inside the injection pump may have stuck parts, etc.

Mine had less than 10 hours run time after reset. IP arm was stiff, turn out the dog bone looking part in the pump had broken. I may have broken while tring to start the set with stuck pump plunger. You can take the pump off and try soaking it in carb cleaner to see if that frees it up. But it may need rebuilt, not hard to rebuild. Try www.ambac.net for info on the pump.

Spray all the linkage with wd40 and move the linkage by hand sometimes it helps unless the problem is internal. Be sure when the stop solenoid retracts the IP linkage moves up also. Sometimes it needs a little help the first couple of times. If the lever is all the way up and you still don't get any fuel it could be internal. Also when the fuel pumps are running are you getting return flow to the tank?

Found the problem. Plunger guide broke. Rubber spacer was also broke. from what I understand, this is common.
