No spark

If you have a test light put your ignition in the on position and hook the test light to battery positive, unhook the 2 pin connector on the ignition control module that has a side by itself, should say P and N, use the test light and touch on and off the P pin and the coil should fire.. if it does replace the distributor pickup, if not have the ignition module replace after verifying power and ground

This truck only has one input which is the camshaft(distributor pickup).. it doesnt use to two inputs because it only has 1 ignition coil and 2 injectors and it group fires them with every coil pulse, theres 8 notches on the distributor pickup that feed an ac sine wave into the ignition modules P/N pins which get converted to a digital on/off signal that can be used to control the coil negative
