99 f-250 dead

[threejacks]

I had a no start problem on 2000 Super Duty showing 240-250 pressure. Problem was injector o ring was damaged. A lot cheaper than HPOP. Check fuel pressure on left and right bank separately. One side showed 240-250 and side showed pull pressure.

its a bad hpop im only getting around 250 psi on start. which is why it wont fire. so new hpop tomorrow will let you know how it turns out. thanks

Are you reading the pressure with a manual gauge or a scan tool. If it's a scan tool you need to try a manual gauge rated for at least 4000psi to eliminate the chance of having a bad ICP sensor.
