I jus got a 91 5.0 lx. First to say I’m cranking the car with a screwdriver At the solenoid because the wires aren’t hooked correctly and it was starting just fine. But now when I crank It I here it turn the crankshaft turn then all of a sudden it disengages from the flywheel and starter turns freely. I’m wondering is it the solenoid gone bad or is it the comple starter itself.
