sounds like you have a few things going on there. I will start with you ignition. you have the wrong switch for that motor. that motor harness has 6 wires in it. some may or may not be used. they go on the proper switch in the following manner. red wire goes to the B or + terminal, black wire goes to the M or - terminal, the black with yellow or white stripe goes to the big M terminal(this is usually a big round terminal that does not look like any of the others), the plain purple goes to the I or A teminal, the purple/white stripe goes to the C terminal, the yellow/red stripe goes to the S terminal, there may also be a gray and a brown wire in the harness also, the gray would be the signal wire for a tachometer and the brown wire would be signal for the overheat alarm. I hope this helps, more than happy to help with any other questions you may have.
