Hi chaps, trying to get it running, spark on all 6 (only when I remove bk/yellow kill wire) and single beep coming on.. hoping ecm is fine..

But neither pumps are priming despite getting power.. pulling the hi pressure pump today to clean and bench test.. Anything else?

Any idea where the obd port is? Looked everywhere cant find it..

Tx

Do you hear the lift pump with key on? Someone here said that they had rebuilt that pump. I replaced mine from Rock Auto with generic MARINE low pressure pump.

The VST (injector) pump is a different story. The pump is inside (I know- obvious). If the engine sat for a long time, the gas/oil inside turns to goo. Common problem- the float needle (aluminum) corrodes to the (brass) seat, preventing gas from entering pump housing. There is a drain plug at the bottom of the housing. Fuel pressure should be 35-37 psi.

BTW- make sure the pee hole hose is clear of obstructions. Blockage could cost a melted piston.

Ok, removed and cleaned vst tank, tapped pump and it started again. Low psi pump was also stuck, opened it up, jumped the transistor a few times and both are running strong!

Never found the port lol - but its firing right up now
