Distributor pickup coil - OBD error 54

Had an starting issue, cranking, have fuel but not start, specially just after turn off. Key trick and got code 54 - means the camshaft sensor's signal is missing.


Replaced sensor with one from old distributor. 


wire insulator is cracked, need a tape there

changing pickup coil of 91 HO distributor needs full disassembly of distributor, will change it with later model one. They have an identical connector and pinout.
