ok so i replaced the starter on my small block about 3 wks ago. now it was working great until one day... just a click well i fiddled with wires and still nothing happened. pushed the car out of the spot to bump-start it but before i pushed forward again i figured id try it one more time... and this time it worked. brought it home parked it and it started again. later that day it just clicked again then started a few hrs later. so the selinoid is engaging just not spinning the motor. should i return it or look for something i may be able to fix. its a pawermaster starter. thanx for any help you might offer.
