Besides Clark's garage, what is a proven way to test the AFM? All the Clark's garage testing has been done. Values are good. Still having a hard start and rough idle. ICV is 10 months old.

Take it to another car, install, see if the symptom follows the part.

Whats your fuel pressure at the rail while cranking/running? And after the car has sat 20 mins?

Fuel pressure cranking 3 bar.( 3 bar FPR from lindsey.) Running haven't check. I have replaced the check valve at the pump. It takes about 3-4 cranks then starts,rough idle, then somewhat smooths out.,about 5-10 minutes. Thank for reply.
