Car Forum / Honda Cars / November 2005'91 CRX HF spontaneous engine shutdown
For the first time ever I had the engine just shut off on me while warming it up this evening. No sputters, no hesitation, no nothing - just up and quit as if I had turned it off myself. Battery is functional as the stereo and headlights were still on. I started it again and there were no further problems. Anyone have an idea what's going on? FWIW it has about 112K and the ignitor was replaced back in '93 or so. No other mechanical problems and it gets all scheduled maintenance. > For the first time ever I had the engine just shut off on me while > warming it up this evening.

'Curly' How old is the distributor coil? The igniter is old enough that it should remain a candidate as well. Are plugs, ignition wires, distributor cap and rotor, air filter, fuel filter, up to date? If not, may as well replace these so you can eliminate them as contributing factors. Use OEM for all but the air filter. Otherwise, I don't think you can do anything meaningful, and without spending a lot of money, until the problem gets worse. -- Honda home studies: http://home.earthlink.net/~honda.lioness -- > For the first time ever I had the engine just shut off on me while > warming it up this evening.

It happened again today, this time while driving. A mechanic suspects the main relay, but he really can't test for it - it fails or it doesn't. He also thought the idle was abnormally low and suggested a throttle body cleaning. > It happened again today, this time while driving.

I am almost certain that it is not the main relay. I would suspect the igniter or the ignition switch. The ignition switch was his other hunch, but when I mentioned the igniter he said it absolutely wasn't related. The shop in question is Clarke's Discount - anyone in Eugene or Portland Metro have experience with them? I would not rule out the igniter, ignition switch, distributor coil, or main relay. These are among the most common causes of no starts for early 90s Hondas. See http://www.tegger.com/hondafaq/faq.html#startrun for more information, including checks you can do for each. After warmup, at about what RPM does your car idle? Read the RPM gage lines carefully. Elle Owner, 91 Honda Civic LX > It happened again today, this time while driving.
