i have a 90 jimmy that i bought about two months ago. about a month after purchasing it, it began having starting problems. when i would turn the key nothing would happen under the hood, no click, no battery sounds, nothing, so after a day or two screwing around i decided to try to hit the starter, this temporarily would fix it. I decided to replace the starter and solenoid altoghether. this seems to work but the third or fourth time i started it with the new starter, it failed to disengage. i heard a wierd noise, and then realized the starter never stopped. it wasn't grinding like when you keep the keyforward after it starts, it was just spinning and i could hear it. then i began unhooking the negative battery cable, but before i finished the starter stopped on its own. did i buy a faulty starter? do i have or create a short in replacing it. or was it originally just a bad connection? any help will be appreciated

It sounds like there is a short to me. Check for a short between the cable coming from your battery to the cable going to the actual motor part of the starter.

I would not think it's a short,would'nt a short cause a fuseable link to fry. I'm haveing the same kind of problem with my 95 jimmy. I just put on a new starter and when I hooked up the negitive battery cable the starter turned on and stayed on till I unhooked the cable. I did not have the key in the ignition. Can't wait till you find out whats causeing the problem.

well i got a new more expensive starter from a better car prts store and it seems to have fixed the problem
