We are all kinda right.
You need to jump the terminals or slots where the relay plugs in to get constant FP power. Then you can check the rail pressure thing.
SAI is secondary air injection. It's a pump that runs for a minute or less on cold startup.
CPS (crank position sensor) is passenger side and views slots on the flywheel. Typically your tach does not move when cranked if this is bad.
