Crankshaft position sensor , PCM - engine computer problem , blown fuse - power to the coils ,ASD relay . Testing would need to be done to find the cause . Viewing wiring diagrams an testing for B+ voltage with a DMM - digital multi-meter . Do you know how to do that ? Free wiring diagrams here http://www.bbbind.com/free-tsb Enter vehicle info. Year , make , model an engine size. Under system click on engine ,then under subsystem click on ignition . Click the search button then the blue links . One at a time . Check for B+ voltage on the drak green with orange trace wire at the coil's - is there B+ voltage there ?

Yes, but it may not be the wires. Inspect carefully, and replace damaged parts.

Well the 4 cyl engine uses a coil for each cylinder, and the 6 cyl uses one coil for all 6. Both systems use signals from the engine computer to fire the coils. So the RPM circuit would involve the engine computer. No distributor is used.

You problem reside in the cause of the fuel injector not getting the proper amount of fuel this can be caused by the MAP (manifold absolute pressure). To a MAF (mass airflow) you have both sensor, Disconnect the MAF does it stay running and also inspect the MAF air duct for cracks and false air leak,From the MAF to the throttle body. with the MAF disconnected and it stay running the MAF is the solution ,as for the MAP if it can stay running with the sensor disconnected the MAP is the solution

I'm not sure if the Northstar has it anywhere. Just for your info though, the firing order is as follows:
1-2-7-3-4-5-6-8




Fig. 4.6L (VIN 9 and Y) Engines Firing order: 1- 2- 7- 3- 4- 5- 6- 8 Distributorless ignition system


Hope helped (remember rated this help) Good luck.

3.0L (2V) = 1-4-2-5-3-6

3.0L (4V) = 1-4-2-5-3-6
