If the momentary power wire is not receiving a signal when the key is in the start position you have a few options to check that are quick and easy. The most likely cause is a failed clutch safety switch(assuming it is a manual and since you're experiencing this issue, it probably is a manual). Another great bet would be to test the continuity of the momentary power lead using a millimeter. If it isn't one of those, you most likely have a failed ignition switch. Hopefully that isn't the case. Good Luck!

Sorry I forgot to mention it's automatic, every thing was working when I started this job.

Cool! Same difference. Automatics have a natural safety switch that performs the same function as the clutch safety switch. It will prevent the starter from getting power while the car is I drive and can easily fail, killing the starter's power.

Considering the engine swap, I'd say the odds are also pretty good that the wire was damaged during removal or instillation. I would carefully check the wires, connectors, and pins on the engine and transmission. If everything checks out visually, test the continuity of the momentary power wire.

I tried park to neutral I don't think it's neutral safety switch I did manipulate that wiring harness, put a new protective covering on it. Can I contact you again?
