That does have a possibility of causing a leak down. Sadly I do not have a huge amount of knowledge on the CIS system, But if the Pressure regulator is failing can cause your issues. My 944 pressure regulator failed, and would take several seconds before firing off. like the engine would crank like ten times, changed the regulator and problem solved. silly question, but have you verified all the fuel lines in the system? seeing if you have a leak lingering. The crush rings can wear out and not torque correctly. replaced all of them in my 924, least 7 of them were smashed and leaking.
