1989 YJ Starting Issue? Electrical?
Ok. It a 1989 2.5 5 speed yj. Until last friday it ran fine. I had Tuffy do some welding on the exhaust and every since it will not run. They replaced the computer. Then the fuel pump was not working. I put the new fuel pump in and it now pumps fuel. Only problem it still will not run. As for the electrical now when I touch the brake pedal the hazard lights, radio and gauges go haywire, Also when I turn the headlights on the hazard lights, radio and gauges also go haywire and the headlights them selves do not come on. Any help? Things to check?
