Aloha guys i just swapped a 3rz into my 97 tacoma. The previous motor ran good den one day burned a valve so i swapped the motor. They both had the 2 coil packs on the side. I left my harness in the truck and plugged it into the new motor. Now it cranks but no start. Has fuel and good fuel pressure but no spark. I probed the coils and each coil has 4 wires and 2 of the wires has power when the key is on.. im thinking a crank or cam sensor but not sure where they are located. I appreciate any helpful suggestions thanks guys.
