P0320 = No Crank Reference Signal
P1296 = No 5V at MAP
P1391 = Intermittent Loss of Cam/Crank Signal
>From the sounds of it...i'd pull the Crank sensor and check the tip.
They're prone for failing (seen several) but easy to fix (no oil mess).

Subject: DML: OBD II Codes - P0320, P1296, P1391
Soon after washing my '01 4.7L 5-spd truck, it started to develop a misfire
of sorts and now no longer cranks. The odo spits out P0320, P1296, P1391
which led me to think that I had a bad or unplugged (high-pressure
degreasing) crank position sensor. I've removed the plug and cleaned the
contacts on both the MAP and CKP and my problem remains. Any ideas? Does
the oil level lie below the CKP such that I can just change it if need be?
I'm gonna check the wiring for continuity tomorrow but forsee a new sensor
in my future.
