My guess is that even if the AFM flap didn't get pulled open when
cranking engine (it likely does though), the air bypass (CO adjuster
screw) would allow little air in. Details of the AFM being used as in
input to ECU when starting engine, might be mentioned in the Digifant
section of the Bentley? I know that section describes functions of
various inputs like the coolant temp sensor.

Zoltan: what engine? Coolant temp sensor and wiring to/from ok?

My thought regarding the fuel pressure residual test was dripping
injectors at shut off. Check the plugs once the hot start issue shows
up? See if they're wet with fuel?
