Was anything done prior to this occurring?
Was the distributor tested?

Reflashing a defective computer won't fix anything, and reflashes address emissions and performance issues, not no-start problems. Besides that, Chrysler Engine Computers are the last thing to suspect. They just don't cause that much trouble. Have you checked for diagnostic fault codes?

Have you checked for fuel pressure or did you get hung up on the first thing you found missing, the spark? A real quick test is to measure the voltage at the ignition coil, any injector, or either small wire on the back of the alternator. You should see 12 volts there for just one second after turning on the ignition switch. You might need to check that with a test light. Most digital voltmeters don't respond fast enough to show that pulse.

What's important is does that voltage come back during cranking? That will determine the next step in the diagnosis.

Vehicle is equipped with distributor and for no spark condition, that should be the first thing to do. I wonder why they recommend a new PCM.

Well we had spark before, And we didnt have power to injectors. So we thought maybe a Used Computer would work. Once we switched it, It locked up the Body Mod.

Do you have spark now?

Pulsing of injectors are also related to the distributor.
If the dealer can't handle this, then you need a new dealership in town.
