A faulty ECU is a common no start or random stalling problem with these cars. These can also cause issues with erroneous check engine lights, idle control problems as well as emission control & cold or hot start problems. Low power & lean running are also fair game. I have also seen fuel pump relay turn on faults (ECU won't turn on the fuel pump), as well as an condition where the high speed injector driver has failed. This causes the car to sit and idle fine, but it won't accelerate. Price this unit new or used, you will see that this is a fantastic deal. Comes with a 30 day functionality guarantee, please see the details related to this on the return policy details section of this listing.
