My daughter smoked her 2011 malibu 2.4 ecotec engine by not changing the oil often enough. I bought a 40,000 mi. engine of the correct codes from a salvage yard and installed it in her car. When I try to start it all that happens is the starter drive will engage the flywheel but the starter motor will not rotate. The battery shows 14 volts. The engine is free and rotates. All grounds have been properly cleaned and reattached. I thought the starter was bad so I bought a replacement. Same results. I have checked the fuses in all 3 locations and they are good. Tomorrow I will check the starter wiring system and the TR switch. ( neutral safety switch ) Any suggestions of possible solutions are welcome. Thanks in advance.

Test the starter at the starter by bridging the battery terminal to the starter motor terminal. If it doesn't turn, then the starter is bad or the cable has no power.
If it turns, then try the key. If that doesn't turn it, then check the relay and the fuse for the starting circuit in the underhood fuse box. If necessary, you can swap a relay from a non-critical circuit (AC, etc) to determine if the relay is bad.
If it seems to check out, then apply 12V to the terminal that sends 12V to the starter solenoid.
Test the other 3 pins on the relay's socket for 12V and a switched ground. There should be 2 pins with 12V and one that switches on a ground when the key is turned.
