I just rewired (conversion harness) my hatch from OBD0 to OBD1... everything seems to be working, except when i went to drive it, it ran like a wet fart and threw a code 9. CYP Sensor.

Something in my distributor wiring is wrong. I repinned the OBD0 plugs to fit the OBDI distributor... does anyone have a diagram of this, or any clues to which wires i have switched up?

Thanks!

If it runs, you got the pin out more or less right, but some of the sensor polarities reversed. If the idle is messy, the TDC polarity is reversed, after that you play around with CKP and CYP polarity until all your codes go away.

i'll try that... thanks!

 

i checked that... still no worky.

new problem... it would fire up this morning... but would not idle for long. we rechecked all the distributor wires, changed around polarity, but now we are getting no spark at all! we set all the wiring back the way it was when it WOULD fire up but run like poopie, still no starty. i replaced the coil and ignitor, and STILL no spark!

i've checked my harness, check a boomslang harness, 2 p28 ecu's, main fuel relay, etc. i'm out of ideas and it won't start and we have a race next weekend!

ANY help would be GREATLY appreciated!

 

you wont make a obd0 dizzy work fine with a obd1 ecu. the CKP reads pulses differently on both dizzy's

it's an obd1 dizzy w/ an obd1 ecu...

and it runs fine

problem fixed

thanks for the help

time to roll the echc H1 field!

 

What was the problem...

... and what part of NC, if I could ask?
