1987 toyota supra trouble starting

Many have posted already but the "relay solution" seems to solve this problem. i about went crazy trying to understand why my supra wouldn't start but the older they get the more the contacts/wires come loose and corrode, they all should be replaced on all parts of the engine.

Basically buy a 6$ 4 prong (or 5 prong relay depending on whether you want to have a kill switch) and mount it on the fender wall(or wherever). It allows for a brand new wire (10-14gauge) to directly connect the battery to the starter when turning the ignition key. I put in this fix Sunday night and so far no problems, starter sounds much stronger.(Also check the + on the starter and make sure its not loose or corroded).
