Not being able to diagnose the latest no start issue, I decided to breakdown (ok a play on words ) and buy a FORD error code reader. While there are several good ones available on line, this one was picked due to it’s 1 day Amazon shipping availability. Also purchased was their 6’ code reader extension cord.
The code reader seemed well made (see comments and pictures at the end) and the instructions are reasonably clear and correct. A tough task when the user is anxious is rushing to get it hooked up and reading.
And it does work – with a running car or a car that failed and stored its errors in the EEC-IV. Remember not to disconnect the car battery when the SVO fails or is failing – before the connecting the code reader. Otherwise you will get a “code “10” – pass/all clear reading.
The complete system with code reader and 6' extension cord.

This is the EEC-IV wire harness connection located under the coil cover on the driver side. Be sure it’s clean and unbroken.

This is the code reader hooked up WITHOUT the extension cable. It will work BUT it will require the user to balance and support the code reader while the engines gas pedal is pushed to full throttle to initiate the engine running test.

This is the code reader extension cable connected to the engine compartment EEC-IV plug. Soft and easy to run to the driver seat.

The code reader with the extension cord easily reaches the driver seat and allows the user to be seated when instructed to fully push the gas pedal to the floor. You can easily see the error code screen and then look up the errors as they show up.

The code reader was sensitive enough to detect the running temperature was out of range (too low), ignition time out of spec, knock sensor not working, open circuit for the electric fan and the best of all – code 77 – operator error. Haha. Of note is that the reader tells you what sensors are not working but not where the fault lies – sensor, connector or where along the wiring bundle there is a break.

Additional comments that should be taken into account, the code readers plug terminals were not extended fully to lock into place. Terminals needed to be pulled out and have its locking tabs pushed out to lock them in place. Also, the 2 required AA batteries are not included.
