My Truck suddelny Died

[Nori]

since youve already replaced the CkPS, and if it is a known good sensor installed correctly dont rule out the main engine relay. the engine compartment fuse box. sometimes the relay board solder joints fail. chased a situation on my truck for about a week. the main engine relay solder joints were funky. the location of that fuse/relay box exposes it to extreme temperature variations and water.

as far as the pump, put a fuel pressure gauge on it and jumper the fuel pump relay. if you dont get pressure THEN rip the carpet up. pulling everything out and pulling the carpet up takes way longer than jumping the relay.

usually with even a generic scanner you can watch the engine speed signal, to verify CkPS operation.

How do you get to see that?
Do I need to remove the entire fuse box?
Or does the inside just come out?

CKPS is changed, fuel pump is changed, relay changed, checked fuse box for corrosion.
Still the engine doesn't run......
I am about to give up on my truck, but any other advise?
I need help....
Or else, I might have to get rid of my truck.

Sounds like you may have to take to a repair shop that can plug it in and see where the failure is.

Did you check all fuses?

Yes. I took the fuse box out as well to see if there is any corrosion.
No luck.
I am going to call the Dealer to see if they can tow to their shop and see what is wrong with it...
I worked on the truck till 1:00 am last night.
Just can't figure out what happened.

Isn't there some type of relay type thing in the passenger side of the engine bay that has a reset button on the top of it? If you haven't tried this, might be worth a try. Mine tripped one time for no reason.

You dont need visible corrosion on the interior fuse panel for it to be a problem, trust me, I speak from experience. You can even as PT. There is an IDM in the panel that will die then all you will get is crank no start. I bet if you put an ammeter on the positive wire to the coil pack while cranking you will get nada.
My fuse pane had no evidence of corrosion!

The day after your wife told me to pull the plug on the truck, we replaced the fusebox and the fucking truck fired up!

No DTCs, weak output from CkPS. Last thing I'd ever have thought it was the fusebox of all things, leave it to Land Rover.
