In a 1993 Ford E-250 : It must be a V8 cause the 6 cylinder is an inline ( straight ) engine that is 300 cubic inches / 4.9 liters
Ford says the 5.4 liter V8 engine is ( 330 cubic inches )
The Ford E250 van typically has eight fuel injectors, as it is equipped with a V8 engine. Each cylinder in the V8 configuration has its own injector, making a total of eight. However, if the van has a different engine configuration, the number of injectors may vary accordingly. Always refer to the specific model year and engine type for accurate information.
In a 1996 Ford E250 with a 5.8L V8 engine, the ignition module is typically located on the side of the distributor. It is mounted directly on the distributor housing, which is found at the rear of the engine. To access it, you may need to remove some surrounding components for better visibility and ease of replacement. Always refer to a repair manual for specific instructions and safety precautions.
