90 mustang gt starter prob
Ok heres the lowdown... when I start my car engine starts fine but starter continues to turn over. I have to take positive cable off battery to make it stop... It is a 1990 Mustang Gt 5.0 5 speed fox body... I have changed this so far... starter, solenoid, ignition switch, alternator. ran just fine started with no problems for a day then went to start it the next day and started doing it again. it continues to turn over after I shut engine off and take keys out of ignition.. pls help am now confused..

something is shorting out. the fox has a very simple starter system. If you can jump the solenoid, and the car starts, but the starter does NOT stay engaged, the problem is before the solenoid (ignition etc) if it continues to crank, id suggest you start replacing cables, then check the starter again.

red solenoid wire
The next time your starter continues to crank over with key off, go under the hood and pull the red wire on the solenoid, the small red wire that pushes on the small threaded post, if when you pull this wire off the cranking stops, the ignition switch is the culprit or wiring to and from, if the starter keeps cranking when you pull the red wire then its the solenoid on the fenderwell or on the starter itself if you have the high torque upgraded one.

I went through this last year. I ended up replacing the wall solenoid, the ignition switch in the column, and the starter. The problem hasn't recurred. FWIW, when I replaced the wall solenoid, I took extra care to make sure it was well grounded. I think that it's possible for a short in the starter itself to somehow cause the solenoid to arc internally and remain closed. At least, that's the only explanation I could come up with after I replaced both the switch and the solenoid.

Well gonna try to replace starter and solenoid tomorrow also may have found something in the grounding.. top bolt hole on solenoid has pulled metal on sidewall out a little so top bolt on solenoid is not tight. gonna hammer back a little bit of get bigger bolts. see if that helps...
