I have a 1991 toyota 2 wheel drive 4 cylinder fuel

Had the same problem with my 91 4runner. Turns out this is a very common problem with toyotas. Also it is not a hard do it yourself fix. I've posted my solution to rebuild the starter without removing it somewhere on this site. What has happened is the electrical contact in the starter has been burnt by the heavy current and 1000's of starts. So the condition gradually gets worse. If you can do the work the repair parts are about $12. I suggest you fix what you have, as buying a rebuilt starter is a **** shoot. With a $12 parts fix , and a few bruised knuckles, you should get another 100000 miles from your starter. Search the web for clicking toyota.

check fuses and any fuseable links
