I hooked up my battery backwards on my 1998 Mastercraft Sportstar. I fried the alternator which I replaced but now the engine cranks but the injectors do not spray fuel and the engine does not start. None of the fuses are bad at the ECM nor did the 50 amp breaker blow. I had a tech come out and test and he said that I need a new ECM. This doesn't add up to me. I would change the ECM out but Indmar doesn't have any more and the manufacturer stopped making them. I NEED HELP!!! I don't know if i should trust the tech that the ECM is fried and if it is what do I do now that they are no longer made?????
