Crank and Cam Angle Sensor Testing... Strange results

[MarcVIII]

I'm diagnosing a no spark. I'm following this:

<<first you need a multimeter

CAS is the rectangular plug and crank is the triangular plug.

Disconnect CAS connector.
Measure the voltage on harness side pin 3, the red wire, with the key turned to on voltage should be 12 v or more.
Then make sure you have continuity, 0 ohms, on harness side pin 1, the black wire, to ground.
Then measure the voltage on harness side pin 2, the blue and red wire, with key on should be 4.8-5.2V.
Reconnect CAS.
Measure voltage on pin 2, blue and red, while starting the engine it should be 0.4-3.0V. With the engine idling it should be 0.5-2.0 V. If you have 0V your cas is dead since you should get some sort of volt reading.

its the same for the crank except the cranking voltage will be .4 to 4.0 v and the sensor wire, pin 2, will be blue and white. Idling is 1.5 to 2.5>>

My Results:

CAS Key on, red/3 14-17v
CAS Key on, black/1 0v
CAS Key on, Blue w/ Red 7v
CAS cranking, Blue w/ Red 3.3v

CPS Key on, red/3 14-17v
CPS Key on, black/1 0v
CPS Key on, Blue w/ Red 8v
CPS cranking, Blue w/ Red 5.3v

It seems my sensors are working, but the voltage is WAY high. Is there something upstream that affects voltage?

My interior is torn apart and I read somewhere that a relay needs a good ground or it'll click and make starting issues. Could that be related?

have you checked out coil and power transistor?

have you checked out coil and power transistor?

Any write-ups on checking a 2g coil?

And I'm doing it tomorrow, just ran out of time.

Have you checked the fuses and relays?

You don't get over voltage from fuses and relays, they simply effect when you get power and how many amps you can pull on that circuit. All the voltage for these sensors comes directly from the ECU. You may have a bad ECU which would explain the spark problem. Try and check the voltage at the source.
