my f150 1994 4.9l slitt has no spark ive change everything on the truck that had to do with spark
Did you check timing chain and gears? If the chain has jumped on a worn gear it will not get spark. or is it your crank sensor?
Another thing to check is the distributor gear to make sure the pin did not shear, seen it happen many times.
Pull the distributor and check the pin for the gear on the shaft...
Did you replace the stator in the distributor?
