Whats the procedure to check the IC pump? I dont think ive ever had an issue - but wont know how to "check" it.

Log IATs. Anything around 180 is a failing pump.

Right on -

It's as simple as 1,2,3. And #2,#3 are pretty easy to do.

Periodically check your fuel pump relay.



Earlier cars a single relay which gets hot when it starts to wear out, causing the connecter to melt and have poor connection. It exhibits problems similar to a bad CPS. Replaced my CPS 3 times, not fixing my stalling/not starting issue. Replaced the relay and connector, no problems!
