My forklift died in the middle of loading a piece of equipment on a trailer. The LPG tank had about 1/4 a tank left. I changed it out for a full tank. The truck cranks but doesn't start. I get 12v to the distributor as well as the regulator shutoff valve and solenoid when turning the key to run for 2 seconds before it shutsoff. When I go to switch the key to run the engine cranks uniformly but I don't ever get 12v to the distributor and therefore no spark. I know that I am getting lpg out of the regulator in that first 2 seconds--key in start.

Dealer suggested ignition switch but it cranks so I feel like that is not it.

Anyone know what would prevent the distributor cap from getting power during ignition?

Anyone have a wiring diagram for this model?
