we are working on a 2004 Cummins ISL 400 which died on its maiden voyage. running just fine, then shut off... no spitting or sputtering, just shut off and would not restart. plenty of fuel at the filters. it has a brand new ECM and now shows a code for speed sensor. getting tired of throwing new parts at it. we know just enough to be dangerous. some of the DC voltages at the ECM seem to be low. HELP ! where do we look now? Don Colapietro 239 940 6199 Thanks
