Troubleshooting a HD90 mark IV drill electrical issue. Engine will not start. The hour meter doesn't work, so that being the trigger for a relay that triggers the fuel lift relay, I am wondering if this is an issue? Also the fuel pump doesn't work, I ran a series of jumpers to supply power to the fuel pump, and a couple other things and it started. I have a wiring diagram but it doesn't show some things that are on this equipment, like a solenoid on the bottom of the injector pump, and what looks like a temp switch on the left side of the engine that is wired to this solenoid. And info on how to fix this would be appreciated.
