HELP TRUCK DOES NOT CRANK OVER
Truck will not crank over and starter relay does not click and starter does not click.
Batteries brand new a week before NSBU work Ignition switch new as of today NSBU new as of last week but that is when non start problem started Security light does not stay on but I did try a security reset for the heck of it Replaced NSBU by the book 10+ times using both new and old NSBU to rule out that the new NSBU was bad. Replaced because every morning truck would have a shift range inhibit and I would have to clear the code with EFI LIVE Did the NSBU switch perfectly using the metal tool and truck in neutral. Truck pulled into garage fine under its own power and NEVER had a no start problem except when batteries were bad. Did work on Jan 10th Truck finally started out of random luck the 17th. Truck restarted a couple times that night Next day truck will not crank again. No blown fuses Nothing changes when shift lever is moved through the gears while key is in START position. HELP I am depressed this was the last thing I was doing to my truck to get it fixed up for selling and now I am looking at spending hundreds at a shop to have them diagnose an electrical problem which could take them days to diagnose. Truck is going in middle of the upcoming week if I can not figure out the problem tomorrow. I have wasted 2 weekends and every night of the week for the past 10 days trying to figure out what is wrong with it. What makes it more confusing is it started a couple nights ago after a week of not starting and now is back to not starting By not starting I mean no cranking over of the starter Batteries are not dead Starter relay is new Gauges and everything power up with the only code I got was a SRS U1000 the one time it did start on the 17th. __________________ |

Ya mouse had chewed about 30 wires under my fuse panel starts fine now but I have shift range inhibited codes P0841 p0843

841 and 843 are transmission fluid pressure related. I changed the flywheel in mine last month and didn't quite have enough fluid on hand when I refilled it. It was in the low area on the stick but kicked the same codes. I read where it could be a stuck valve under the spin on ... But luckily for me it was just adding more tranny fluid. As soon as I got the level perfect it quit kicking those codes. Been couple of weeks now.. No problems.
