Can a bad crank sensor cause the computer cutting power
It'll crank, but the ECU will not see RPM and then...poof! You get nothing. One way to find out if the wheel is on, is remove the trans, bellhousing and clutch/flywheel. It'll stare you right in the face. Or, you might be able to remove the crank sensor and use a borescope (real small diameter) to see if it's there, and hand crank the engine slowly watching for the shutters. I'd try that first.

Took the transmission off. Placed that on and have everything back on. Will that cause the pcm to kill power to the starter and fuel pump?
I have never personally tried it with it off, but if the ECU won't see an RPM signal, it won't fire/spark etc. I know my Holley HP won't fire when the signal is not present. I'm just guessing Ford will have a safety spot, like the old EECiV system that had a "timer" built in.

Car runs great. Thank you for the help!
