Customer Question
Still having issues with car...
Still having issues with car. Found a Honda manual and it appears to be a defective ECM (we have checked all wiring for opens, shorts and grounds and had mechanic test the new alternator and MCU. Got another from the junk yard but now car won't start any ideas why. It appears it needs to be flashed, is this something only the dealer can do? Does the ECM need to be in the car or can it be done outside the vehicle.

Is there anything that we can do without the key cylinder since it was bolted to the car. We do have the immobilizer

Your answers were clear and the diagrams were perfect. Dealer wanted $87 for an hour of labor and even I did it in 15 minutes.

EdUSA

HONDA PLATINUM was great. I really appreciate his help. I was ready to trade my new Honda until he told me to wait until I got 3,000 miles on it and my gas mileage would get much better.

SummerUSA

I took the Power Steering O-Ring service bulletin linked from JustAnswer to my Acura dealer, and not only did they no-charge the o-ring, they also replaced the power steering pump at no cost.

Gary RStevenson Ranch, CA

Wonderful service, prompt, efficient, and accurate. Couldn't have asked for more. I cannot thank you enough for your help.

Mary C.Freshfield, Liverpool, UK
