Sometimes my truck won’t start

Yes it usually doesn’t start in the mornings, as in today. It started right up yesterday, I worked all day, shut it down, got in this morning and nothing, not even a click. Changed the ignition switch, but nothing. As I wrote earlier, I’ve changed the starter, firewall relay, and now the key switch. I ordered a new 20 amp fuse and will change that tomorrow

 

Hi Lester. Yes I have that part also. I’m gathering as much info as possible to try and narrow it down. The funny thing is it starts most times and runs great, but I travel far even though I’m a day cab and I don’t want to shut the truck off somewhere off the beaten track and not be able to start up again. Sometimes I let it sit for a couple of hours and then it starts.

 

Hi guys. Well here I am again with the same problem. Got here at 3am and nothing. Stopped at Peterbilt yesterday and he recommended changing the big breaker on the frame rail and the clutch switch. I was only able to change the breaker and it started, but not this morning. Hopefully it will start soon and when I get back I’ll change the clutch switch

 

Yes I agree, but I bought it and I know they’ll give me a hard time returning it. I told the service manager I was able to able the truck without pushing the clutch in which tells me I didn’t need it and my cruise and jake work fine. I remember in my 95 pete there was a relay of some sort behind the driver side dash. I heard something clicking in there this morning. I opened the dash And went to turn the key to listen for the click and the truck started
