97 died and wont start

Have a 97 f250 with a 7.3 . Shortly after adding some questionable fuel the truck stalled. First time trying to restart it sounded promising, but nothing. I've done some testing and seaching

I put 911 in tank n drained filter housing.
Put in new filter n 911 in housing.
have great pressure at shraeder valve
Hi pressure oil pump is full
No oil out of side of injector
wont start with icp off
will run on starting fluid ( I know I know)
all fuse good
batteries are great and have been on charge to prevent from draining


Really in a pinch, don't have money to be shooting in the dark.
I am very mechanical, but have limited 7.3 experience
