I am having an issue with a crank no start, no error codes on dash, machine ran then died, changed to another propane tank still no start. will start and run with starting fluid, have checked fuses and switched around relays. I have propane to the throttle body I have power to the fuel shutdown solenoid. I have tried to look up wire schematics but blocked by a pay wall. Does the oil pressure switch enable power to the ecm to activate. start /run

Thanks
