I have a 93 360 magnum I bought at salvage trying to start out of truck .It will crank won't start jumping across starter what do I need to do to get fire to coil .I have the ECM hooked up .any help will help

 

Is the crank sensor in place? Sits behind the passenger side head. Got a flexplate, or flywheel on there for the sensor to read?

 

Yea sensor is hooked up I don't know how to get power to ECM I have complete engine harness hooked up to ECM it has three pig tails that hook to another harness I thine one of those should have my hot wire to feed ECm

 

Pcm gets power from the battery and the ignition switch. Do you have the relays/fuses hooked up? You need the ASD relay to supply power! I would suggest to get a wiring diagram. The new motors are not like the old school ones where all you need was power to the ignition and starter.
