91 Accord doesn't start
Hi All,
My 91 Accord with 146K miles won't start since 2 days. I browsed thru' the NG and I found that the symptoms match the famous "main relay" problem. So last night I tried more diagnosis. Here' what I found - - when I turned the key to run, I couln't hear the fuel pump whirring. It is posssible that it is running and I couldn't hear it beacuse of road noise (heavy traffic) - when the "check engine" shuts off, I hear a click; so I *guess* the fp is shutting down - when I turn the key to start, it sounds like it *wants* to start but can't. - tried to jump from my Odyssey as well as from AAA guy to no avail. Please help me determine what could be broken. I plan to replace the MR anyway tomorrow (what the heck, it will probabaly break soon anyway!) TIA. Raj |
Re: 91 Accord doesn't start
good chance that's it. especially if you just had a very hot or cold
day (relay). it could start working just as fast as it stopped working. try again when the relay might have gotten to a more normal temperature. after changing it it will probably start right up as usual.

Then smack the dash with your fist and see if the fuel pump runs. If so, it's the relay all right. Your car will now start, but may not run consistently. 'Curly' ----------------------- |

You mention the click when the "check engine" shut off. Mine had the same click, even though the relay wasn't working properly. It is a rather complicated relay, actually two in one, with one dependent upon the other. If either switch fails, the car won't run. I think the easiest test is to pull the connector and put two jumper wires in place of the relay. On my '91 *Civic*, they connect from 1-3, and 5-7. I can only guess that it is the same on your Accord. I'll try to draw a picture of the connector. _______ ________|_______|________ |_2__|__4___|___6__|__8__| |_1__|__3___|___5__|__7__| It's up to you if you want to drive with these in place. The big danger is the fuel pump will keep running if you crash, possibly creating a big fire. The other caution is to disconnect wires when not driving. Good luck, Jason |
