Frankenbee died on me going down the highway. Fuel is good, rpm are good so CPS is good, Injector Buzz test is good so IDM is good, engine oil pressure is good so LPOP is good but I have no ICP so by reason of thinking my HPOP is bad. Only other thing to check is pull the Hpop lines and try to put compressed air into it to see if I can hear a leak from an injector oring. But I am doubting that as I would think all the injectors would have to have bad ones for absolutely 0psi on the ICP.
Died? Just died like you shut off the key? I mean with the history of this truck, and all of the electrical gremlins, I'd start there. Do you have a multi-meter? Can you check voltage coming in?
Ya I am getting voltage everywhere it is supposed to be. When I unplug the ICP the computer starts reading the default 2000+psi. I geuss I could pull the ICP and crank it over to see if I get a fountain out of the hole. That would be a real pressure test.
