Question about 1991 Geo Metro
The coil can be checked by measuring the resistance between the primary terminals, should be 1.33-1.55 ohms. Also check the resistance between the positive primary terminal and the high tension lead, should be 10.7-14.5 k ohms. Hold the spark plug wire (I usually use an old plug inserted into the bood). about 1/4 to 3/8 inch away from the block while cranking and see what kind of spark you get. If you get a good spark, look for something else. jeb
