Do your batteries have a good charge on them?May need to hook the charger up to them.May have drained the HPOP as well.I bet it will start when you get good oil pressure to the injectors.

IIRC, don't you have to bleed the air out the GP hole or something like that?

There's an allen head plug on the top of the HPOP reservoir. Remove it and fill it up. Takes almost a qt. If it's within an inch from the top, that's close enough.

You can take the plug off on top and fill it there. How much cranking have you done?

I know when I pulled/replaced my injectors it took enough cranking to make me start thinking I mucked it up. Almost 2 bat charges worth. I did not top of the HPOP....

Can you meter the batts while cranking? You need around 10.5 v for the IDM to fire the injectors.

Did you do the fifty cents mod?

It's putting a quarter in the UVCH clip, to keep it from disconnecting. But the truck should still start on one bank.

ok i've charged the batteries twice since yesterday morning. i cranked on it til i started worrying about the starter. not solid cranking but for 10-20 seconds and then a short break in between. still nothing, not even a sputter. the oil resevoir is just a little under completely full. is there anything else i can do? do i need to bleed the air out of the lines? i havent tried the 50 cent thing yet.
