Somewhere I have this CIS fuel pressure test kit....IIRC, there is a test port on the fuel distributor. You would connect one line up to the test port and the other line to the cold start injector line.. I believe and this would give you system pressure and upper chamber or lower chamber pressure...and you were supposed to see a certain difference between them..I dont recall 100%
