I have a 98 SHO 3.0 converted into a buggy and I am having an issue where it will die and seems to get flooded out. When I try to restart it, you have to floor it and crank on it for some time, and it does not always refire. Sometimes you just have to let it sit for a few hours and then you just walk up and hit the key and it fires right up. I have replaced the MAF and the TPS. I have several codes showing up on the check engine light and most of them show that the ECM has no power. How is this possible if the car is running and driving? I have checked power and the pins are hot. I am down to the point where I think this could be ECM related and would like a model number that is compatible off EBay so I can just replace it cheap as a test. I find plenty of 12A650 ECMs but none that are -AA-MR My problem is I don't see the exact model number match to mine. Anybody have any idea what ECM would be compatible or have an idea what else may be wrong?
