I have both an A 9 L computer and an A 3 M computer. The A9L computer will not pulse the injectors. The A3M computer will not shut the fuel pump off. If it is possible I would like to have both of the ECMs fixed. If not I would like to get rid of them and just get 1 from advance. What do you think is the most economical right now. Thanks in advance. I will update my status and information shortly. I was a member at 1 time but lost my password.
