Hyster H120FT:
No engine power.

I have a Cummins QSB 3.3 In a H120FT that has low engine power and cant seem to find the problem. Fuel pressure is good new turbo and have swap just about everything I could from a sister lift. I have cummins insite but have not been able to get it to communicate at the cummins engine 3 pin triangle diagnostic plug on the engine harness. I am new to hooking into this plug but heard that any cummins has that plug to communicate insite on. I am using nexiq usb link and link 2. Anybody have any suggestions? or ran into this before?

No throttle solenoid or cable. Cummins common rail.

Typically Hyster/Yale use IFAK interface. Does this truck have a throttle solenoid?
