Totally agree on the CAS. Fuel will be tested today. But if I have spark should not the car start with starting fluid? Maybe my dizzy is off that 1pm mark? Seems that I can only set it in 2 positions when attempting that 1pm landing. Sometimes close to 1pm dizzy adjusting bolt is to far to the right or to far to the left. Im going to try the other position with starting fluid and then proceed with fuel pressure test.Bottom line is this - you're getting a spark.
To get a spark, the ECU has to switch the igniter on/off, to know when to switch the igniter on/off, the ECU has to see the CAS output from the distributor.
If the ECU sees the engine being cranked without any signal from the CAS, it sets a code 42, which you get if you leave the distributor disconnected - you're NOT getting a code 42 when the distributor is connected.
Perhaps it's time to stop focusing on the CAS sensor and move on with basic troubleshooting - you have spark, do you have fuel? Have you checked the fuel pressure yet?
