HELP!! What did I screw up?

[c6crouch]

Greetings,

Well my truck, E99 F250 SD, has been leeking from the HPOP, so I bought the complete seal kit, non-seviceable plug, and gasket. I also bought the fuel bowl seal kit as well. Well good news is I think it was the non-servicable plug that was leaking, bad new is now it WONT START!!!

It turn over, the fuel bowl fills up, oil pressure gauge says there is pressure, but nothing. I tried spraying a tiny bit of starting fluid and that makes it start for a second, but not sure if that even means anything. As I said, I rebuilt the fuil bowl and HPOP. I thought I was very careful to put everything back together right but what could I have messed up. Is there a common mistake that could lead to this.

Thank you for your time,

Charles

what is your ICP? Do you have a way to monitor it?

[melmount]

dont use any more starting fluid or anything else.

Make sure your hpop reservoir is full of oil. If you tried crancking it before you filled the reservoir, you could just have air in the system.

[dazdillenger]

and how long did you crank it? These trucks take a couple minutes to start when there is air in the oil system. the gauge on the dash is for the low pressure oil pump.

I take it you removed the entire HPOP to do this? Which plug are you talking about, the one on the rear of the pump that faces towards the turbo?

You might double check that the bolt attaching the gear to the HPOP is tight. I had one once that got ****ed on me. I torqued the bolt down but soon as I cranked it the gear shifted and loosened up. It wouldn't build ICP pressure till I torqued it again. If you had a way to moniter ICP pressure you could tell this real quick.

Oops, I put in c ocked and it thinks I was talking poopy. My bad.

also, you should make sure the pump shaft is SPOTLESS and both the shaft and gear are DRY in order for the taper to seat properly.

well i got it somewhat fixed. now i can only start it when i unplug icp(itll stay running). when its pluged in itll only run a min then shut off. what are some causes of this? i have no way to see oil pressure, im sure its not holding pressure.

[dazdillenger]

you do have a way to monitor oil pressure-all you need is a dvom. Very simple. If it stays running with the icp unplugged, try changing the sensor. With it unplugged the computer sees a default value of I believe 2200psi.
