91 Civic electrical problems
Well I have now replaced my main relay(houses the fuel pump relay) with a
new one from Napa(I had previously re-soldered all the points) and I replaced the ignition switch with OEM Honda part. But I still have a problem with the car simply running great one moment and then the next it's like someone turned off the switch. I can be driving and the thing just cuts out like the power was turned off to it. Two years ago it died while driving it and I had to have it towed. At that time I towed it to a mechanic who replaced the distributor with a Carquest one. Two years before that, I had myself replaced the igniter when I had starting problems. What are the chances the distributor is bad again?? I ran the car tonight and let it idle and sure enough it died after about 10 minutes. So I pulled off a plug wire and attached a spark plug to it. Cranked, but definitely NO SPARK at all. So do I need another distributor? When I checked the coil with a meter, it was within the Haynes book numbers. I could just replace the coil and igniter, but would I be better to replace the whole unit? There is no Check Engine light. What are the chances the ECU computer is bad as opposed to a bad distributor?? thanks in advance, Gary 91 Civic Hatchback 5spd,1500cc,178kmiles stranded in Hawaii |

So, the problem could be the lack of heat sink grease on the igniter (probably improperly installed by Carquest) or a hairline crack on coil. It's probably time for a new distributor, since by this time I don't believe you mind replacing another expensive part without a complete diagnose. ECU are reliable but did the check engine light come on then off normally during the symptoms or were there any LED code on the ECU box? Is this a DX, a LX, or an FI? -- Also, put several groups in one posting. |
