LB7: No run issues

[blk smoke lb7]

Hey guys,haven't been on in a while but I'm in need of some help.
I had an issue with a bad oil leak and wound up pulling the passenger side head.It wound up being a bad valve seal on the stem,finaly got around to putting it back together and I had issues with the lift pump not working from sitting so long.Took the pump apart cleaned it and it worked soooooo now the truck starts for a sec then shuts off it does this everytime.I took a line loose and it sprays fuel out,didn't see any air even tho I deleted my top side filter.The battery's are fully charged and the charger is on it to back up the battery's so it cranks fine.I rechecked all wiring and it all seems to be connected well.What am i missing????Thanks in advance for any help guys much appreciated.:hug:

I'm sure you checked but codes? Rail pressure when it runs?

Sounds like a VATS issues. Security light turn off?

The truck was acting weird when the lift pump wasn't working and the security light wasn't on all the way but really dim.There are no codes.Rail pressure only shows like 800 then hits 1600 fires for a sec then shuts off.Is their a reset procedure I can try for the security just to try something?I know the older cars you turn the ignition on and let it set for 20 mins shut it off then try and start but I did that already and no go.

Need around 5k to run.

Dim lights? Sure the alternator and batteries aren't shot?

If you leave the key on the run position does the padlock go away?

I think the relearn on these was turn to crank and back to run leave for 10 minutes. Repeat 3x.

Or just do a relearn with a tech 2.
