With my C900 (late 1982 build) I need to plant my foot right to the floor on the throttle when starting and hold the starter engaged for about 5 seconds until there is enough fuel pressure at the injectors. I'm suspecting the cold-start switch might not be working properly, but once the fuel flow to the injectors is happening, the engine runs fine. I need to pull out the injectors and check they're not blocked, and also check the spark plugs to see if their fouled up, but I don't think they are. I might take out the fuel distributor and check it too. >2.

(There were no more 900 5 doors >after 1980.) I find nothing out there to replace it. My C900 has the 3-spd auto transmission. It works fine but when engaging 'drive' after the engine has been warmed up the engagement is very 'strong'. There's plenty of transmission fluid and it's not contaminated so it might just be a band adjustment issue.
