Confirm you are getting full throttle arm movement. Holding throttle arm up 100% have a helper turn it over. Any help?I have a mep-002a that is very difficult cold starting. I have changed the glow plugs twice with NEW (champions first time, welman second time). The manifold heaters appear to be fine. I've checked the amperage and resistance on the GPs and heaters and they are in spec. It takes way too much cranking. It starts to fire on one cylinder almost immediately but will not come up to speed. Sometimes I have to crank it for two minutes before it will run on its own on one cylinder. Then it runs much too slowly on one cylinder for 20 or 30 seconds before the second cylinder comes on. Once the second cylinder fires, the thing runs great, makes all kind of power. I am totally frustrated that I can't identify the "cold" cylinder. I have pointed an inferred thermometer all around the exhaust ports, cylinder head and elsewhere and detect any temperature difference between the cylinder that fires and the one that doesn't. My problem kind of sounds like buck's one cylinder problem, only I have half as many cylinders. I wonder how he made out with the compression test?
I would then check compression on both cylinders and compare.
If nothing shows up there then check injectors. Probably good, but might be physically sticking and only properly moving the pintle once the nozzle opens up in tolerances via heat or something.
