I would trace down the no-spark issue. That is likely your problem. I don’t know what motor you have, so its hard to recommend a more specific direction to go in though. Its clearly electrical. So check fuses & relays. Good luck...

4.7L’s have coil-over-plug setup. When you tested spark, did you test all of the coils or only one? Test each one. One may be bad, but the others may be good. After you’ve tested each coil for spark, you can start walking the problem back from there (e.g. making sure the coil is getting good power & ground etc). Don’t jump to the PCM without ruling out all the other possibilities (like a broken wire).

Good luck...
