Won't Start

[BuddyZ]

Purchased a beat up 2002 V6 from a guy at work and purchased a rear ended 2003 have pulled the motor and trans and it was running well then the daughter who helped do the engine swap wanted to swap the interiors, now it won't start. Switched the dashes out but put in the old cluster,ignition key and transponder and pcm. The power windows and mirror don't operate and the radio is dead except for the cd changer is cycling, will start with ether but no fuel pressure.

those cars have about 3-4 different wire harnesses, the reason you're not firing is that you used the wrong one for the car.
Once again they're are 3-4 different harnesses. When you use the proper harness your car will fire. Find the original.
