Hello everyone I have recently bought a 1970 302 project mustang. It seems to be almost rust free and in good shape but struggles to run. When I first got the car it did not run at all but it did turn over. After changing the battery I realized my starter is most likely shot since it was making an awful nose when trying to start the car. Before rushing to change the starter I replaced the solenoid, with no luck i then changed out the starter. Once I did this the car started up but still made a slight grinding nose near the starter also it didn’t seem to want to reave up, this also could have been since I only ran it for a short time and it hasn’t started for years. I checked to make sure the teeth on both the starter and flywheel weren’t chewed up and they both look good. I now believe that my starter is not disengaging since this would make sense for why it’s making a noise and not reaving up (since starter gear is holding back flywheel). but With this being said I am not 100% this is the issue and I don’t know on how to go about testing this or what would cause it to not disengage (possibly a faulty wire on the solenoid). If anyone has some tips please let me know.
