Truck died going 50 mph and would not restart. I turn the key to run and nothing. I can hear the injectors buzzing but it will not turn over or crank.
I CAN jump from the battery and the truck will crank. However it seems to be in limp mode. It will start off in 3rd gear and won't

Tow/haul light is flashing.

The wire harness that goes down to the fan clutch
is chewed up and frayed so I'm assuming that may have caused an issue. But i have unplugged the sensor to the fan clutch and it still won't start. I can hear the injectors buzzing but when I turn the key to crank it, it does nothing. Just clicks. I've cleared the codes and these keep coming back.

 

Check fuse f2 22. It tends to pop with the fan wires being shreaded. It will also gove you that p0611.

 

All fuses are good. Ive checked the 22 fuese about 35 times....Ive taken the tranny pan off and removed the transmission range sensor that is inside the pan. Maybe it went bad idk....Im hoping this is the problem

 

U1059 code keeps making me think the truck doesnt know if its park or drive etc....Do the trans ranges sensor tend to fail? Maybe the shredded fan clutch harness killed the TRS sensor?

 

Just to make sure f2 22 is a 20amp under the dash.

 

that is correct

 

Iirc, ckt 361 runs in both. Do you have power and ground at the ficm relay?

 

Not sure, how can i check that?

 

Remove ficm relay and use volt meter.
Check the tech folder.

 

What is the tech folder? Sorry, newbie here....

UPDATE:

I checked all fuses, grounds, and relays...all look good.

Code U1059 kept coming up after clearing codes which made me think it was the trans range sensor in the transmision.

So I replaced it, filled the tranny back up with fluid and cleared the codes. Still no start, no crank. U1059 kept coming back.

I finally gave up and took it to the dealer today. They called me back with an update of the diag... and told me that the trans range sensor needed to be replaced. (i told them i just replaced it).

The service guy asked me if i changed the harness to the trans range sensor, I said no i didnt.

He said that the harness probably needs to be replaced since the sensor should be good. Codes lead to communication of that sensor.

$700 for parts and labor to change the harness. Valve bodies need to be removed to access that harness, refill with fluid, etc. He said the tranny does not have to be removed.

QUESTION-

Is replacing that harness something that i can do myself???

 

Pretty simple job however the o ring seal is a pain on the bulk head. Iirc we charged 5 hours.

 

Thanks for the reply..

I'm fairly skilled with working on cars/trucks and i have a pretty good collection of tools

Is this something I could handle on my own? does it require special tools, etc.?

 

Pretty much just an 8mm for the body and 10mm socket for the pan. Not all the bolts come out of the valve body. Im sure there is most likly a you tube of it.
You dont want to seperate the valve body just remove it whole.
Use a torque wrench when putting it back in so you dont distorte it.
