Nissan Repair: nissan 200sx no fuel to cylinders, hall effect sensors, crank angle sensor

Question
1988 nissan 200sx with the 2.0L CA20 engine.
I checked ignition getting spark at plugs. compression good. I am getting fuel to the injecter rack. Will start and run if you inject fuel into the intake.Checked fuel pump 50psi. Bypassed fuel pump relay no luck. Used noid light on injecter connections no flash on light. Ran modeIII diagnosis on ECM it gave a 22 code which by the Haynes Manual is fuel circuit.Have no idea where the EFI relay is? Side note was running great then one afternoon hard to start ran rough then died been that way 2 weeks now.

Answer
Lindy,

The sensor that tells the injectors when to fire is defective.  On yours it could be the distributor or the crank angle sensor if you do not have a distributor.  These are basically hall effect sensors if they are on the cam or crank.  So, find the crank sensor and replace it and you should be ok.
