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.
