I hooked up the AE to my truck to start troubleshooting it. the problem is that when the truck gets up to operating temp it shuts off and wont start again till it cools off.
when it colds everything is fine and dandy but after it shuts down it only shows around 160 psi on the ICP. I have already replaced the IPR and it's doing the same thing and the ICP is functioning properly.
So I have a leak in the system somewhere when the oil gets to operating temp.
My question to you guys is, How do you tell if you need new injectors or just new o rings?
