I have a 91 loyale , a few months ago it would not crank .( key on battery good) , I used a jumper wire on the starter solenoid lug it fired easly so it wasn't the starter . it would always start the first time in the morning . after driving it would not crank . unless I jumped it. . so I installed a start button directly from the battery . all good. for a month . now it will crank but not start . im getting 8 volts at the distributor. when it cools down maby an hour it will fire . I am thinking its the ignition switch . any thaughts ?
