Nozzles came in today. Gonna drop them off tomorrow. :jumpin:

The control lever worked fine, it was the plunger that would stick at the top of the stroke. I know now that the pump internals are spotless at least. As for the injectors. I just went ahead and purchased a set of new nozzles off ebay for $24.50 each. Hopefully that will get this thing back...

I'm making progress! I reassembled the pump and reinstalled it. I didn't have a brass 1/8" rod so I used the back end of a drill bit. I don't see how it could harm it unless I was being hamfisted on install or somehow forgot to remove it after install. (I could see it breaking the gears off...

I studied the Ambac IP pdf I found online and figured out how to tear down the pump. The throttle lever was the part that was causing it to not tear down. Have all the parts soaking in parts cleaner now. It was a mess! There was dirt/rust/crud all in the housing. The plunger was stuck and...

I'm thinking now the injectors are fine. I pulled IP and found that the plunger is still sticking at the top of the stroke. I've squirted a mixture of gun bore cleaner with PB blaster in it to see if it will unstick. I tapped it back and forth a few times. I'm able to place the tappet face...

Just pulled the DV apart and screwed it back in flush. It's clean and free now, but it's still not flowing. Looks like I've got issues in the IP. Just wondered if there's anything else I can do to get the head to pump again.

Ok I've been reviewing the documents I've recieved on the pump. I had the delivery valve backed out. That allowed it to flow the ports out like it was doing, but it's not fully pressurizing the ports. Looking at a cut away, the DV should be flush with the housing. The DV allows fuel to flow...

I'm going to wait on the injectors first. I'll plug one up and see what it does with the pump first. If it still doesn't work, I'll replace the IP then.

I dropped the injectors off at the diesel shop, they hope to have them checked out maybe by the end of the week. But I'm questioning the IP now. When I got home, I plugged the return line and turned it over. I get fuel out of all the four ports. But I was able to take a rubber band strap and...

Lift pump is working, when I take the cap off the HH I get a couple foot stream from the lift pump squirting fuel out. I took apart one injector, it seems the needle is stuck on it. I was able to get it loose and the nozzle would squirt a stream of fuel with the spring and spindle out. But...

I removed the cap/spring/spindle from one injector. I left that connected to the line and tried turning it over, nothing came out of the injector body. Not sure what way to go now.

Well I decided to pop the injectors out of the head to see what they're doing. And I'm not getting any fuel out of them. I do get a dribble of fuel out of the lines when cracked on the cylinders. But nothing out of the injector tips. Guess I'll start taking them apart to check them.

I picked up a Onan 12.5 generator last night. Basically it's the same as the MEP-003. At lunch I tried starting it but wasn't getting any fuel. I checked the forums and found mention that the center bolt on the hyd. head can stick. I took it apart and found the valve slightly stuck in there...
