i think you wired it wrong. i think you wired it wrong.
If you are installing the engine in an exact model that the engine is coming out of, the harness should not be needed. If there are any changes in model, sensors or anything else then the harnesses will not be interchangeable.
Interchange would only be possible if you had a ENTIRE donor car, harness, transmission, axles ,mounts.etc
The Taurus SHO has a timing belt that must be replaced every 100,000 miles. All other Ford Taurus's have a chain that should last the life of the engine.
It is important to have a diagram when making changes to a cars engine. An engine diagram for this car can be found in its maintenance manual.
11 years of changes... not at all likely to work. Check with a local auto salvage yard or engine rebuilder, but don't expect it to be possible.
Do a "wiggle" test. Grab the harness in different areas and wiggle it. Watch for the area that changes the problem you are having and zero in on the problem spot.
Never. The Taurus engines...both the Vulcan and the Duratec V6s...both have a timing CHAIN that lasts the life of the engine, not a timing belt.
