Hi folks, I've got a mitsubishi, fg18k, ef25a-85707 with a starting fault.

It has the impco fuel system with 2 seperate units. They have both had diaphram/repair kits fitted.

The truck takes ages to start, but once started it stays running and starts first time every time once warmed up. It also starts easily from cold if you press the gas release button on impco unit.

I'm getting gas from the high pressure unit to the low pressure unit, but I'm guessing nothing from the low pressure unit?

Any ideas, as mine are slowly running out?? I've got a spark at all for plugs.
