MEP802A not starting . Notice anything major in video

[Leonardo82nd]

I agree... sounds like the metering pumps are borderline at best. Some times the pins will be loose enough to move just by tilting the pump side to side.
If you can't flick the pin side to side with 1 finger there is a problem.
I have had good luck soaking them in the gallon size can of Gunk carb cleaner. Let it sit a day or 2 then with then submerged pump the plunger several times to work the cleaner into the pump, then work the lever a few times and soak a couple more days. rinse and repeat....

Update : I soaked the pumps for a few days in Gunk, no luck.
The levers on the pumps are stiff, and don’t seem to be loosening up at all
I see on @CallMeColt video how loose they normally are. Mine are no where near that loose.
Any suggestions where to buy replacements?
Or other methods of correcting this issue - with stuff pumps.
green mountain has them available (on back order)

It would be a good idea to post something in the “parts wanted” section. You will surely get some responses there. I believe the MEP-802A and the MEP-803A units use the same IP’s. Also, look in the “parts for sale” section too. Good luck!

Also, these pumps come apart fairly easy. Maybe you can grab a cup of coffee and carefully disassemble one of them in a clean environment. Lay the parts out in the order that they came apart. You may be able to see what’s causing the drag in the metering valve that way and repair it. If you’re successful with one, then do the other.

I've just had the same situation on a recent auction buy. The rear injector was frozen. I removed it and removed the top so I could get a good dose of penetrating oil in there. After a good soaking and manually working the fuel rate selector back and forth, it loosened up.

I put it back together and back into the machine. Fired up and ran perfectly.

I recommend taking the tops off and getting something in there that has some lubrication value while working the fuel lever back and forth.

I have some that were takeouts that are probably good. Message me directly about them.

ATF. They are a lubricant and a detergent. They also will burn when injected into the combustion chamber. Also, it will clean a bit going through the injector as well. I have purposly primed systems with ATF & let them sit for a few days, then did this a few times with great results.

Thanks for the info on checking the fuel rack. I had a MEP802 that would crank but not start. I went through all the steps in the TM. Then, per your video, I pulled the plug and pushed on the fuel rack and it would not move, lubed it up and got it unstuck. Generator started right up.
