I started working through these. Airflow switch OK.
Removed the air flow sensor charging pressure relay, removed its cover and confirmed it was working OK.
Put it back in the car and tried another start. Hey presto, problem fixed - whatever it was!
Don't you just hate that Spent hours tracing lines through the wiring diagrams trying to figure it out and it fixes itself!
