Toyota Repair: STARTER, starter relay, toyota pickup

Question
MY STARTER JAMS SOMETIMES ON MY 1991 TOYOTA PICKUP V6 2 WHEEL  

DRIVE  I HAVE REPALCEAD THE STARTER 3 TIMES LAST ON JUNE 10, 2010 I CAN TAP THE STARTER AND IT WILL START

Answer
I would recommend removing the starter and inspecting the flywheel ring gear for any sings of damage if that is ok, try replacing the starter relay under the hood and possibly the ignition switch. Finally, try using a starter from toyota not aftermarket.
