I just replaced my original starter with one from a pontiac 350 just wondering if the third yellow wire coming from the coil needs to be hooked up? There were only two terminals on the solenoid I replaced and there were three on my original. I got it to turn over but now it will not start. Someone told me that the yellow coil wire coming from the starter was not needed as it was just something with the voltage? I believe it was connected to a letter R on the soleniod and a puple or black wire was connected to the letter S all my wiring is original on my Firebird? Is it possible that when the starter went bad it took out my coil? I took one of the plug wires to see if there was spark but there was not any but it was daylight so I really dont know if it was there or not? If not the coil what else could it be? And how do you check to see if the coil is getting any voltage or current/
