Turn key, no crank...everything else is normal
Ok guys, here's what i'm working with. The truck in the my signature started to develop an issue where you'd turn the key and nothing would happen. All the normal lights would come on GP's would cycle clutch pushed ALL the way in, nothing. Then every so often on the 3-4 times it'd start.
So far i've put in a new key ignition/lock cylinder, clutch interlock/start switch and no dice. So today i started looking at the solenoid/relay on the passenger fender. Jumped it using a screwdriver across the two big posts, fires right up. So i figured that was my culprit. Threw a new one in, same problem. Turn the key, nothing happens. Jump it with a screw driver, fires like clock work.
So now i'm looking at where to turn next. The GPR controller makes an a lot of clicking on and off during the start sequence. Could a faulty controller effect the ability to actually get the truck to crank over? What about the solenoid on the actual starter, should i be looking there too?
Any help would be great!
