Well I’m guessing it is my cp3, have done all the testing and while the truck is cranking over it only has 300psi rail pressure and they need atleast 1500psi. With the truck having a reman 10mm cp3 I think it may have been weak and that once it dried out it failed the cp3. Bought a new 10mm cp3 and all brand new fuel line so we will see what happens. I’ll keep you guys posted
