So the ol Onan won't run, it runs on starting fluid, but not on it's own.
I have gas in the tanks
I disconnected the fuel line and ran the pump, it spurted a little fuel, so it's not completely dead.

How do I know it the pump is truely OK?
I'd know what to do on a car engine, are these things the same?
I'd put a fuel pressure gauge on it and also pump it into a can to check volume.
I'd like to verify it's not the pump as pulling this beast will NOT be fun, unlike the OE Onan, this thing it wedged in really tight, and is not on a slideout. So tight I cant get at the rear spark plug.

FWIW this is a 6500 Onan Emerald, not the stock genset

Thanks
