electrical i'm sure....car problem is, car worked fine, two days later car won't start, as in, won't even turn over. Battery is good, connections are good at terminals etc... Put new starter on, now turns over fine. Put foot on brake while starting and it starts, let foot off brake and starter bendix kicks into flywheel while running. Put foot back on brake bendix pulls out of starter and runs fine. Can't find any wiring issues yet, and did not alter any other wiring during starter replacement. Any ideas ?

 

replace and check the neutral and positive connection.My car started intermittently for a month. It was a mixture of starter solenoid going bad and + and - cables.Also grounds can keep the car from starting.clean and fix old grounds.Also i added some.

My problem was a mix of all 3.
