7.3 no start
E99 F250
Cranks, no start, no smoke, acts like it wants to
fuel in the bowl, drained and refilled itself, pump is running
oil psi says 2200+
ipr % 36-46 while cranking
fixed 2 wires in harness already
new fuel filter - don't have a way to read psi at the bowl
went through every fuse and relay
cranks at 220 rpm
passes buzz test
only code is p1668, erased it and hasn't came back
oil is full
over 1/2 tank of fuel
injectors ohm out at 3.0 +-
is there a way to specifically test the idm? without just swapping a good one in

probably not the gauge. if you have not done the hutch harpoon mod. I was reading and don't see it in your signature. If the pickup falls off, it will quit running between 1/4 and 1/2. Mine was at 3/8 when it fell off.

Maybe another good reason to install a fuel pressure gauge, and X2 that hutch harpoon mod. Interesting that the bowl filled, but it appears there was not enough pressure to get the engine to fire. I'm glad she's going again, and you have a work around until you're able to make the needed repairs.
