my 1992 ranger 2.3 is not sparking. I testedd the coil pack by switching the back and the front pack around and that didn't change anything. I had the ignition module tested by auto zone and they said it was fine. what else could it be???? just to let you guys know I already changed the spark plugs and the cables going to them.

 

The Crankshaft position sensor could be bad. Get a 194 bulb and hook up two jumper wires to the bulb. Pull one of the injector wires off the injector and insert the other end of the jumpers into the socket terminals. Have someone crank the engine over and see if the bulb flashes.

 

Thanks will try.
