No start when warm

[johnp115]

Fires right up when cold.
Once it's warm it doesn't start. Cranks over but no fire.
Icp when warm cranking 180-200
It's pulling a cam sensor fault so I'm going to replace that.
I've replaced the icp sensor a year ago.
Am I dealing with an oil leak somewhere? Or an electrical problem?

Don't waste your time changing the CPS, you have a HPO leak.

Let the fun begin.
Honestly you probably lost an O ring along the system. Sounds like a small one cause it starts cold. When my Injector o ring (3 top o rings on the injectors) went bad it would tart cold but 50/50 when hot.

ICP needs to be near 500 to fire the injectors.

Run air through an adaptor to the ICP sensor. Pull the valve covers and look/listen for leaks. I didn't figure out it was injectors until I pulled the covers and viola!!


Tons Of threads on this so it's been laid out before. Just read through and figure it out before you just throw money at it.

Best of luck and great looking truck.
