I know this sounds like a familiar problem, but I have yet to discover the answer. My OB started one morning, as per usual, and about 30 seconds after starting, it quit(cranks,no start). There seems to be no spark (cranked with #1 & again on #3) I have checked to see if it's a fuel delivery issue(haven't checked exact pressure) I have replaced cam and crank sensors as well as coil, and swapped ecu from a known runner. I've verified continuity from the ecu to the coil. Not entirely sure where to go next. I'm going to continue checking wiring, any ideas would be appreciated.
