    I have a 91 hatch with a b16A the car was converted to obd 1. I just finished putting a clutch and flywheel in. I start the car and the check engine light is on. I jump the 2 pin connector on the passenger side underdash to pull the codes and i get nothing. The light comes on when you first turn the key on and then goes out. I was thinking the ecu may be trying to relearn information. I dont know too much about the obd 1 ecus. If someone can help me or has had this problem. Any advice would be great thanks.

    Does the check engine light stay on for a long time or does it shut off in a couple seconds? With the obd1 wiring they turn on then shut off like the new cars do. As long as its not staying on it shouldnt b a problem thats y ur ecu is not throwing any codes.

    pull the hazard fuse,unplug the ecu,replug the ecu.put the hazard fuse in and try that..if not..check all your plugs on your motor..

    checked the code when engine running (9) crank angle sensor. I checked timing running like shit. Im not sure where to go now i may be parting out a 91 hatch shortly. I just put new upper arms, lower ball joints, wheel bearings, pads,rotors, calipers, russel stainless steal front hoses( rear disc conversion with stainless lines) i really dont feel like putting more money for a dd. I may just take off what i need to finish my other hatch. I dont think i can replace the sensor which means i need a dizzy. If i am wrong please correct me. I just dont know what to do at this time. Thanks

    which ecu are you using?
    obd2 uses a crank angle sensor obd1 does not (im 99.9% sure anyway) sounds to me like you are using an obd2 ecu...

    did you drive the car before the clutch change with the same transmission and ecu? any issues?

    code 9 is for the CYP (cylinder position) sensor. it's located in the dizzy. what you mean to say is obd2a/b ecu's look for input from a CKF (crankshaft fluctuation) sensor. since he does not have this code, that's definitely not what his problem pertains to.

    to op: check the wires at the dizzy connection and see that they are snuggly in place, and make sure the connection between the dizzy harness and engine harness is fully seated.

    its obd1 not sure on the what ecu. I didnt do the conversion. I was driving the car daily before putting the clutch in. Im going to check the wiring harness to make sure i didnt pinch a wire or anything like that. Its the same trans all i swapped was the clutch and flywheel. Thanks for the advice.
