S14 suddenly stopped (won't start)

[tapu]

Hi,

I have a Nissan S14 SR20DET Blacktop from '95 LHD

While coming home car suddenly died without hesitating..it simple stopped.

Mounted the diagnose cable and it gave me Error Code 11...

I replaced the CAS with a second hand one and the car started...it run ok for a couple of minutes and it died again...(car reached 50 degrees temp)

Diagnose shows again Code 11

Any ideas what to check...?

Code 11: CRANKSHAFT POSITION SENSOR CIRCUIT (0 STARTS AGO)

Engine Mods:
- downpipe + exhaust
- FMIC
- HKS BOV
- piggy back ECUMASTER DET2

Nothing was done to the car for about 4 years..so everything worked ok

I checked today the wiring of the cables and:

Wiring:
CAS harness connector -> terminal B and ground => battery voltage
CAS harness connector -> terminal A and ground => continuity exists
harness connector and checked pin 42 and 52 -> continuity exists
harness connector and checked pin 41 and 51 -> it displays 4.34 as resitance...is this normal?

Unpluged CAS from the engine and checked the voltage:
- one connection displays between 0.01 - 5 V
- and the other one betweem 0.01 and 7v ...is this normal?
