Ok, got up this morning started the car up and moved it so my girlfriend could go to work. Later went outside and changed the plugs on the mustang. Now the car had motorcraft platinums in it, and i put in autolite coppers, heard they work well on this car. Used anti seize on the plugs and dieletric on the wires, cleaned up the tip on the coil, was looking dirty, got in cranked over but wouldnt start. Got out my spark tester, checked from the coil going to the distributor and had no spark. I changed the plugs 1 at a time to not mix up the firing order. Can anyone tell me what i missed? Why did i lose spark? The autolites are gaped to .054.

To clean the coil terminal you had to pull the coil wire off, check the coil wire with an ohm meter and see if you have continuity, you may have pulled the coil wire apart inside when you pulled it off the coil.

not fixed yet, checked the coil wire, about 2000 ohms, got power to the coil, gonna check injector pulse today. i seen that you can loosen the distributor and test it that way, but wont that effect the timing?

ok well, was had my test light on the yellow tan wire on the coil and had my dad crank it over to see if the power was being supplied to the coil when being turned over. The car fired up, and is now running fine. Im assuming the connector to the coil bad or has a bad connection, does that make sound right?

if that were the case performing a wiggle test on the harness area would cause it to stall, if it doesn't you have an intermitent issue that will arise again

Would the problem be with the coil wiring, or should i just wait till it happens again? Where else should i try to look for what caused the issue? Is wiring issues a common problem with fox bodies, dont want to wait till im stranded on the side of the road.
