Do you have a wiring diagram for this vehicle? Have you checked for power on the run circuit and the start circuit on the module?

    You need to check power on the ignition module. It has a run circuit and a start circuit. I do believe the power wires are red and white but I can look it up.

Have no spark. New coil, contr. mod. test good, new crank sens.,new cap and roter


Check for voltage going to coil. If it was running before you replaced the items listed try putting the old cap and rotor back on. Also, check that the firing order at the cap and cylinders is correct.

I have a 92 mustang it turns over normal speed Its getting fuel but not spark. I've replaced The msd coil,msd ignition box,distributer, Silinoid switch,key switch, and the Ignition switch in the...


Since you are getting good spark, I would guess first that your timing is too far off. Use a timing light to check the timing since the distributor was replaced. If your timing is too far advanced or retarded it wont fire up, but do exactly as you mention. Also, be sure your firing order is correct.
