I dont have any wiring diagrams. where to next? How can I test the ECU? Hey Roy I have never dealt with an 89 Civic, but your rotor is indeed turning, right? (just a sanity check to see if the timing belt might have broken - you didn't mention it, but you probably checked it). Also, was wondering if it could be the crank angle sensor? It should be inside the distributor - probably a hall sensor. Not sure how to test those without a scope because the levels are very low/fast and can't see them with a voltmeter - static test may not mean much. Its signal goes back the ECM and drives your ignitor. Perhaps make sure this sensor goes back to the ecm? Also check to see if the wire from the input of the ignitor to the ECM isn't broken? My manual only goes back to 96, so unfortunately can't help you with a schematic - maybe someone out there can help you with that. Hope you find it soon. Remco |

Yes I need to check the pickup coils. After I posted I found a wiring diagram of the distributor. It shows 3 pick up coils: cylinder, crank and TDC. shows to be 460 ohms. I'll check them tomorrow. yes rotor turns. "remcow" <whybcuz (AT) yahoo (DOT) com> wrote in message news:xuvqd.14$tQ3.12 (AT) fe11 (DOT) lga... I dont have any wiring diagrams. where to next?
