On a scale of 1 - 10 with 1 being the easiest and 10 the toughest, it's about a 1.5
I agree though - ECU's rarely fail and whatever is causing the ECU to fail so frequently could be a symptom of a bigger, hidden problem.
He could also be BS'ng you about the ECU being the cause of the car not starting and it could have other problems that aren't as easy to fix as an ECU
Buyer beware.
See if you can find a cheap ECU on ebay or locally and swap it out and see if the car starts and runs, but I would be hesitant to buy and drive a car that goes thru ECU's so quickly.
Good luck.sigpic
