Turn key, no crank...everything else is normal

[EClark]

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!

Usually it's the ignition that wears out over time, but with a new one that's confusing. To remedy my situation I have the starter ona momentary on toggle switch. Turn the key on to run position, and then hit the starter. That is the hillbilly way out though.

Thanks for the help Justin. So I was out fiddling with it some more and couldn't get it to start with the key. Jumped it at the fender solenoid and ran down the road to get fuel, left it running and then came back to the house. Shut it off, and figured what the heck i'll try the key again. Started fine, shut it off, started fine again. I'm going to let it set overnight and try to start it tomorrow when it's cold and see if it has something to do with that GPR controller.

So today I started it 3 or 4 times with the key. No problems. At least it starts.

Sounds like there might be something loose or a bad connection somewhere ...... As far as the GPR is concerned mine clicks for a little bit but starts like a champ every time . Check each glow plug and make sure they are getting the right voltage if so your GPR is working fine.

glow plug clicking is normal. it is the relay turning on and off.

Sweet, Thanks Guys. Hopefully the plugs are alright. I think it was a bunch of bad connections with...everything. Cleaned 'em up and got it home. Thanks again.
