    Thanks so much for this very informative video. Just helped us fix our 1992 Ford Fairmont ECU in our 65 Mustang. We had lost all hope until we watched this today. Fuel pump wouldn’t switch off. Replaced capacitors but still didn’t go. Closer inspection as per your vid showed corrosion to track from leaking capacitor. All fixed in 10mins and now works. Amazing.

    Great repair video. One thing you didn't mention is that electrolytic caps are polarity sensitive. Be sure you match the original polarity. I repaired my A9L myself but have since gone to Megasquirt. Much more user friendly to tune and programmable inputs and outputs. Way nicer if you're heavily modified with a power adder.

    Wow, great video I just came across this You're all set up nice little test set. I have a question, maybe you could answer, I have a1987 ford f150 I'm having a no start issue with my truck. All it does is crank. I have Spark, I can hear either fuel tanks. Fuel pump kick in when I turn the Ignition on the only way I get it to start. Is when i spray starting fluid into the intake. She will start, and then stall. Can this be a computer issue? Also, for the fuel pumps
    I seen your tester had the green light on it. For your fuel pump, I'm just scratching my head. Why this truck won't start not knowing if this could be my issue? Maybe you could help me out.

    very informative, thank you! I wonder what you think of replacing the electrolytic caps with polymer? They are supposed to last far longer than electrolytic but may have some extra complications in ordering the right ones because they act slightly different than the electrolytic ones so maybe it isn't as simple as just matching the voltage and uF ratings. Any thoughts? 🙂

      That coating on the pins is a thick lithium grease. I’ve seen on one occasion where the grease itself was causing an issue. Use a few q-tips and some brake cleaner to clean it off. Wet the q-tips and don’t spray directly on or into the EEC. Yes you need to clean both sides.

      As a general guide I have found fewer than 20% of the capacitors that I've tested have remained within a 10% tolerance of their original specification. These things are 30-35 years old. Capacitors seem like the components that take down all vintage electronics. If your truck is a keeper then I would change them regardless of physical appearance.

      There is no reprogramming required after replacing the capacitors. The best way to check the computer is to install it in the vehicle and run its own code scan.

I would never build a tester that is able to check the entire computer as that would be far more elaborate, complicated and expensive than what it is worth.

      Thermal paste is only for putting between the physical package of an I.C. and a heat sink that goes on tip of it.
      The thermal paste fills the tiny irregularities between the surfaces of the I.C. and the heat sink, and makes the thermal transfer between the parts much more efficient. It is not used as a coating on a circuit board to help weatherize it.
