To much pressure in fuel bowl???

[Amnima]

It is a 99 f550 I replaced the high pressure oil valve on the hpop. Truck will not start now... it will run on ether but that is all. Gauge on dash shows that it is building oil pressure when i crank. When I open the valve on the back of the fuel bowl it blows fuel hard onto the ground like there is to much pressure on the bowl. Any suggestions on either problem?


I think i need to replace the whole hpop it was acting up before i started working on the truck.

DONT USE ETHER/STARTING FLUID, its like a drug for a diesel engine once it gets a taste it will get addicted and not start with out it

I was just trying to get the air out of the lines by getting the engine running. I don't like using either!

There's probably just air in some of the lines, oil or fuel or both. Probably fuel if it runs on ether but not without it.
Just crank on it for a while and then let it sit. Then repeat. And keep going till it starts. Once it does keep it idling high.

If you DO run ether, disconnect your glow plugs. If you don't, it can cause early detonation and not do good things.
