My 87 Camry turns over but has no spark. The coil is getting 12 volts. The primary side of the coil is measuring 0.5 ohms, like the books says. The signal gernerator side of the distributor is measuring 160 ohms between pins G1 and G- and between NE and G1, just like the book says it should. Anyone know what voltages are supposed to be coming out of the ECU to the signal gererator? And on which pins. Any suggestions?
