I just noticed this loose wire and I’m wondering is this the culprit from keeping the car from starting. A little history... the car was running fine then one day it would not crank. You car hear it trying. Mechanic said the timing was off and didn’t want to touch it because it was too much work. Months pass, and someone told me to try replacing the Crankshaft sensor which I did lastnight but haven’t tried cranking the car yet. During the process I found this loose wire... can anyone tell me what it connects to pleeaassee. Thanks

This is the wire.. driver side engine front. Appears one end is grounded and the other end goes ?????
