Complete Newbie at a loss... 97 8.0L won’t start
I’m throwing the book at this truck and running out of ideas. Bought the truck 2 months ago, have since done plugs and wires and a fuel pump. Fuel pump was just changed last week. Up until yesterday the truck was running, but at an idle the rpms would fluctuate. Started driving down the road and truck acted like it was falling on its face when I stepped on the gas. Truck stalled out and hasn’t started since.
So far things I’ve checked are:
there is spark at all the plugs
fuel pressure at the fuel rail is 40 in the on position and 50 while trying to start.
used a noid light on the rail and the injectors are getting signal
used an ohm reader and tested the crank and cam sensors. According to what I’ve read they are on a 5amp circuit and should read at about 5 amps dropping to just above zero when starting. Both do just that
ASD relay is good
All fuses seem to be good
Disconnected the battery for 20 min to drain system
I’ve run out of ideas, can use any advice I can get!
Thanks in advance!!!

it tries to start, but never actually turns over. No different results stomping the gas as from just cranking.

the fuel injectors are getting signal, but will check to be sure the injectors are working tomorrow

Im almost certain it was a Delphi pump
