I have a friend I'm helping with a Northstar 4.6 he put in an old Ford.
We have the PCM and the engine wiring harness. VATS has been defeated but we can't get the motor to run.
We can crank it and have confirmed ignition and think we have everything powered that should be, as well as grounds.
The problem we seem to be having is getting the injectors to pulse.
The only tech info I have is a Mitchell Wiring Diagram for a 2007 XLR Engine Performance Circuit.
Anyone with some ideas?
What does the PCM need to "see" to enable start/run?
I am thinking once it starts/runs we can work through what will likely be more issues, these are great motors and having one in an old Hot Rod throws back to the days when having a "Caddy Motor" meant you had some power.
