Did you replace the ignition module CDI unit , on my 97 Fleetwood Bounder it is on the front firewall opposite the driver, but some earlier 460s had it mounted on the distributor, it was moved because engine heat was a problem
Even though mine is on the forward bulkhead/firewall the OEM part died and had to be replaced
Symptoms very much like yours, ether will fire with a weaker spark, has a lower flash point than gasoline
There are 4 different versions of this CDI unit, and your engine will only run with the one your ECU is programmed for, it took me three tries to get the correct one,
I suggest you insist on buying the Ford OEM part, ,Not aftermarket , NAPA sold me the wrong $80 part and refused to
Refund my money saying they had to special order it,
