Fuel source for cranking - Fixed vs Fuel map

Hi all,

Have an issue I am trying to troubleshoot and need help.. My injectors are all wired in correctly and on bench test I am able to get them firing.

When I try cranking the engine with "fuel source for cranking" set to Fuel Map, the injectors don't fire during cranking. (with the rail out)
When I try cranking with "fuel source for cranking" set to Fixed the injectors do fire but the car doesn't start.

All the maps for the M111 190e are set to fuel map so I am pretty sure this is the setting I need to go with. Any ideas why they're not firing under this setting.

Can you take a log of cranking? If "fuel map" is injecting no fuel, it probably means something else is wrong.

hey. bear with me this was my first time attempting to log. connection kept cutting off so not sure it captured anything.

If not I can try again on Monday.
