87 bird, 6.0/4l80 no start
6.0 swap won't start.
Doesn't Seem to be getting fuel. (no hptuners signal)
No spark.
I have power to coils and control power for packs.
Hptuners, says CKP P0335, but I put a new one in it and no change.
triple checked the wiring to Crank sensor and plug, it "rings" out just fine and it has 12.7v at the right pin, with key on.
Have a 2002 6.0l/4l80e "411" computer and Hptuners mods just to get it started... emissions off, and vats (fuel pumps work)... do you have to do a "write entire" maybe? I just did a calibration write
the PNP switch wires at Pcm are now grounded and still no start.
I have power to the switched source during cranking and run.
Hptuners isn't showing, rpms,or inj pulses,
I am getting o2 values, tps values, coolant temps, voltage readings (pcm.)
I am going out to re-check all grounds.... what else could it be?

Re: 87 bird, 6.0/4l80 no start
grounds are all great, I have way more then I need, continuity everywhere.
did a write entire and NOTHIN....
I am still getting P0335 "CKP no signal for 3 sec", I have a new one and the original one that came with the motor, and neither one helped.
It cranks great, with no sign of a hit... it does have gas and about 52psi at the rail, plugs and wires are new.
am I right? that if you aren't getting any rpms in Hptuners then the PCM isn't getting a CKP Signal?
Maybe I am just looking in the wrong area. This is the only place I have help, all my friends are ford guys (no help) or carb guys (not much help)
what else could it be?
