I have an issue with my 1995 mustang gt. I’ve replaced Fuel pump, fuel filter, Egr valve, coolant temperature sensor. Spark plugs and wires only have 10,000km. But sometimes after driving it and it sits for an hour or so it cranks but won’t start. No codes come with my OBD scanner. Could it be a bad ignition control module or a crank position sensor issue?
