4 weeks still no start
I've got a problem thats had my truck garaged for a month.
I was pushing it hard one day, and it died under wide open throttle. No start afterward.
I went through all the "obvious stuff", and finally determined there is insufficient hpo to actuate the injectors.
HPOP is capable of making 3600 psi, I deadheaded one outlet and tapped a gauge into the other, with the icp hooked up it made 3600, with the icp unplugged it made 1900.
When I reattach the hpo lines to the heads, and tap my gauge into either head, I'm only seeing 200 psi there, and it takes 7-8 seconds of cranking to build that...
Obviously the injectors are not fueling, due to inadequate hpo pressure. Where could this oil be going?
I replaced the injector o-rings, no external leaks, no smoke at all. Cranking engine with valve covers removed, there is no oil spilling from injectors, or around them.
If oil was going into combustion chamber I would have some blue smoke, correct?
Coolant in overflow reservoir looks normal.
What is going on? Thanks for the help!
