HI all. I finally got my truck running and driving a few weeks ago but I have developed another problem. The truck will literally shut off every once and a while, even when driving. Plus it won’t idle for more than 10 or 20 minutes. It just shuts off. Though the ignition is still hot and all the electrical components continue to work. The first few times it happened, when I tried to restart it, the WTS light never came on and it wouldn’t start until I messed with the relays under the hood. Now, the WTS light comes on when it should and it restarts just fine. I’m just worried about the truck dieing somewhere out in the hills and not being able to restart it by myself. The truck itself has not set a check engine light but I still plan on snatching my buddy’s snap on scan tool to run whatever codes that may be present. In the mean time where should I start? Is it possible that my CPS is going bad? Any help you guy’s can provide would be greatly appreciated.

 

Yep sounds like the cps. The new grey ones are like $30 see if that helps

 

sounds like a CPS to me. YOu need a spare even if its not it cause it will be sometime or another.

 

Unplug the CPS and flush it out with some contact cleaner.
I have seen alot of good sensors replaced, the problem really was the connection.
Try it you have nothing to loose.

Ditto. Make sure that if you replace that you replace it with the updated version.

.....X2.......

I have also read the ICP sensor can have these symptoms also....

 

buy several before the price goes back up

 

My Truck was doing the same thing for about 3-4 months. Finnaly it died and would not start back. Found shorted under valve cover harness and that took out IDM.

 

ouch, hate when that happens, not too often

 

well whatever the problem is, its computer related. i switched out the ecm's and it fires right up with glowplugs and all. ran like **** because the ecm codes were different but it started without any problems
