3.4 to 3.8 swap

[QICRNU]

All right here I go. I had a friend that has a 95 3.4L dohc car that his kid blew the motor up in. They bought a 99 3.8 car that had been rolled and still ran. They swapped out the engine, subframe, trans, and entire wiring harness. I cannot get any spark or injector pulse what so ever. Has anyone done a swap like this? Is it even possible. I have both cars here and just need some help. I can get spark if i jump power to the ignition relay. I have a feeling that im missing a wire; ground or power; to the pcm. please help. Phone number is 623-910-5337. Ask for warren

Welcome to AF, get a scanner on it and look for cranking rpms, if none susprect crank sensor, ign module and/or connections, or a bad fuse. PCM also swapped also?. This assumes everything you did was correct, no way to tell from here. BTW check on the fuel pressure specs for the 2 injection systems, not related but a different pump may be required.
