VATS needs to be turned off.

Wouldn't the security light be on?

This is true.. fuel lines backwards? I did that once

Has fuel pressure, just no spark.

i could be wrong but arent the 99-02 computers different than 03+ ??? i cant tell for sure from your post but it seems like all you did was swap the motor only.... if you changed the harness and pcm then nevermind.

but i also had the same problem when i first tried starting mine. it was a missing ground. yes one single ground wire prevented spark. the one apararantly a lot of people miss. its on the driver side of the block down low. check ALL your grounds as they are VERY important.

as soon as i connected it, she fired right up. good luck

It still has the the original pcm and wiring, all I switched was the engine, not the intake or anything else. I will check that ground.

did some more checking, the computers are different but it SEEMS the pcm SHOULD still control it as long as they are both set up for DBC or DBW. but anyway, sounds like its probably that ground. let us know
