I've dug into the EFI diagnostic manual and have completed 16 of the 23 checks. I have a fuel pressure gauge but I'm going to have to construct a way to cut it into the system. Unlike modern fuel systems that have a capped valve stem style connection there is nothing on the Kawi Classic. So I'll have to buy or build a T fitting that has the valve in it and cut it into the system so I can check fuel pressure.
I've got a few system checks that are marginal when tested. Example, one circuit in the airflow meter is looking for 350 to 400 ohms at rest and <2K ohms at full sweep. At rest it sits at 321 ohms, in spec throughout the full sweep. I seriously doubt this is the cause of any failure. Other cicruits are to be 0 ohms and I find 3 ohms or up to 15 ohms. Same with the Throttle Position Sensor. Very close to spec. But multiple elements at or just past the margin of spec. I start work full time tomorrow so the pace of progress will slow. Since I'm slow with this stuff when I'm not working, glacial may be the new pace.
I've got to do a full check on the fuel relay. It has about 9 connections (Test #23 in the manual) but I had proper voltage at the fuel pump two days ago during a check and yesterday I had none. It may be flaking out but again, hard to test with a single set of hands. Onward through the fog.
