Toyota 52-6fg35 problem, error code 4-8

Hello,

We have Toyota, LPG forklift, type 52 6FG35, serial number 10177. It has an electronically controled pedal for driving with potentiometer and electric motor for fuel opening on engine.
The engine doesn't want to start because it doesn't have 12V on the ignition coil. If we manually put the 12V on coil we can start it but the electronic throtle doesn't work. Do you have some instruction how to adjust the poti on the pedal and electric motor on the carburator ? We also have am alarm code 4-8 on the dash. What does it mean ?

Any help would be appreciated. Thank you!

it could be the governor controller but 4 and 8 have to do with the throttle not closing and rpm's not dropping when commanded. the stepper motor should cycle and close the switch next to it when you key on. frequently the actuator tab bends and wont contact switch. look there first.

easier to ask forgiveness than to ask permission.
