Hello guys
I am having quite a mysterious issue here. The forklift cranks good, there are no errors on the display , but there is no spark and no signal to the main injector. The work that i have done for know is : changed the EGI relay, changed the ECM, changed the injector and still no spark and no signal to the injector. I have checked the wires to the ECM from the injector, and they are all good. I also checked the wires to the relays and they are also good. I have changed the capacitor from a working machine, no difference. The ECM has a good negative and positive. Some suggestions ?
The only errors that appear is F-77 and F-75 , but those are for the lift solenoids. I have schematics for the forklift i also have the service manual, but i cannot trace the problem yet.
