Long story short I blew the a head gasket on a 98 tacoma 5vz-fe automatic and ended up swapping out the motor for a rebuilt one of the same. Motor went in with easy, however I can't seem to get it to crank. The starter is getting ground power. All the fuses are good. There is power coming from the ignition and going to the neutral safety switch but I don't think power is coming from it. The car will crank if you bypass everything and crank it. Any input and advice would be much appreciated.

 

Did you swap the harness from the old engine to the new engine??

If yes you might have bent a pin had things corrode on your neutral safety switch

If the harness stayed on the new engine quite possible if not the same year the pins on the neutral safety switch are wired different
