Thread: Isuzu Engine Swops for Dummies

Hopefully someone that has done it more recently will confirm, but from memory when you prime them the primer pump goes hard unless you have something cracked. Sounds like that's not the case for you.

Any chance you've got the cutoff lever in the cutoff position? Its spring loaded to run (position closest to the engine block).

These guys are thinking well! make sure the lever is in the "free" position, just disconnect the cable

EDIC motor isn't connected, and fuel shutoff is sprung to the "run" position, so all should be good...

Had you cracked the injector lines at the injectors?

Yep - not getting any fuel topside.

If you crack an inlet line at the fuel filter and hand pump, do you get lots of fuel coming out?

Kiki pumps are generally a doddle to prime

As I said, I'm gettign fuel to the injector pump. Have cracked the inlet to the IP, get plenty of fuel when I prime the pump, so no problems there. Am getting fuel THROUGH the pump, because I can hear it returning to the tank.

Last try a few minutes ago, I started getting a small amount of fuel to injector#1, but batteries don't have enough go to continue cranking for the moment.

Throttle flat whilst cranking?

Should come up with a good battery and crank then

Although 2 flat batteries is alot of cranking!

Nothing silly like fuel line in jerry sucking from the bottom restricting flow either?
