MS3, just upgraded to the latest firmware (1.4.0). Though, the problem existed on the 1.2.3 beta or whatever it was running before. Issues started after doing the head gasket.
In test mode, I can get the coils to fire. They do not fire under normal cranking, until I stop cranking and they'll fire once (according to timing light, anyway). Fuel injectors are working.
Battery voltage seems to hover around low 10's while cranking. Is that too low?
TS also is showing the sync lights crossed out (see attached). I'm guessing they shouldn't be? A composite log is also attached, which shows some sync errors when it first starts cranking, but then they seem to go away.
