I have an 86 rx that is having an extremely annoying habit of intermittantly stalling on the morning drive to work. after it dies it won't start for about 15 to 20 minutes. I have no tach bounce when I try to start it. I checked power and ground to the coil and it has both but still won't start. All the wires look to be in good shape. Would a coil fail on a cold day? I jumpered my computer and can hear the fuel pump running and I replaced my fuel filter. The distrubtor and cap look fine with no moisture. My other grounds look good but ?. When she runs she runs fine. It's kind of an all or nothing thing. Any suggestions?
