The replies stand, your welcome to prove any of that incorrect...Good Luck!

So, there seems to be some confusion here... Yes the truck ran great for 2.5 years, is this correct?
It started having issues which were narrowed down to bad pcm. The pcm was replaced and truck hasn't run since, correct?
If all of that is right, an important question which has already been stated is, has the cluster, ie PATS, cluster, keys, however you would like to phrase it, been programmed to the new PCM?

Everything is correct word for word, I suggest you research or troll another thread which you at least somewhat understand.

The previous problem, frying out the coil packs is one deriving from the swap...my guess. Assuming a Crown Vic wiring harness was used, big no no lol. Crown vic circuitry, connectors and injector set ups were different. Some of this doesn't matter, but it the part of that does which can have you pulling your hair out. For this reason, always use the original harness. Like I've already mentioned, even the 150 harness differentiated from another, at times changing mid year. Hell they changed the fuse/relay blocks countless times through the 10th generation. Not much, but enough.
The Crown Vic, Grand Marquis also have different upper/lower intakes, also have have very different plenums or throttle body elbows. So TPS and sensors on top will adjust for a truck intake set ups. The car lines use taxi cab intakes (slang) vs truck intakes. Truck intakes are larger and designed to deliver torque.
Swaps are easy, as long as you use only what you need from a doner. Reason for throwing this in, if problems don't arise immediately after a swap after combining too much from the doner, they could develop in the future. Burning up coils could be a result from this (wiring harness).

Correct, PATS come into play for 99 plus models, you can't get around it. You need a programed key. 97/98 PCM's are direct plug and play. But yea, that ended in 1998.

Right, if so, curious if he's aware that has to done. Might not be not be, therefore troubleshooting the coils again. Yea, he won't get coil signal without the pats being dealt with. Really need to here from him at this point, clear some things up anyway.

Yeah.... been following the comments, but the guy with the problem is MIA. Hard to figure anything out like that.
