Having problems with your 1989 Toyota 4Runner ?
New battery, starter, cables, runs fine days or weeks at a time then it goes completely dead. Can turn it off, come back 10 mins later, wont start, try to days later, fires right up?????
Had a similar problem with with my 4runner.replaced most of the fuel and ignition systems with no luck.finally traced the problem to a bad connection between the main relay and the fuel pump.there's a wire harness connection between the back of the gas tank and rear axle.I just replaced it with a solid run from the fuel pump and the relay.haven't had any problems since.
