No Spark

Recommended Posts

Have a 1988 comanche was running before motor swap. (new) 4.0/AX15/NP231 put in. Pulled powertrain running out of a 1989 comanche, So here's my problem: I have no spark. Have power to the coil (yellow wire) And I have ground. I was reading that I need coil pulse to make it work. Is this correct? And if so where does the coil pulse come from?

Also new crank sensor

New cap and rotor

New plugs & wires.

On a completly unrelated note, I cannot turn my motor over with my key. Turn to run position and fuel pump primes everything turns on, but when I turn to start nothing happens, Are these 2 problems related?
