Engine turns off while driving - Honda Prelude Forum

Last week my engine turned off 2 minutes after I left my driveway and I was unable to restart it. Did the check engine light code check and it passed. I then found there was no spark was coming out of the coil while trying to start the engine. Frustrated I let the car sit until yesterday when I tried to turn it on. Coincidently? the battery drained and it was unable to hold a charge so I tried starting the car with the help of a battery charger. Miraculously it turned on with no problems and I drove it for about 30 miles throughout the day and every time I wanted to restart the engine it did with no problems. Last week when I also attempted to start the engine with the battery charger attached it did not start.

Yesterday I replaced the battery and fuel filter to be on the safe side. I measured 12.5V at the battery and 14V when the engine is on. I loosened the service bolt on the fuel filter and plenty of fuel comes out when I try to start the car. I had replaced the main relay, ignition coil, spark plugs, wires, cap/rotor in the past 6 months and the ignition a couple of years ago. Fast-forward to today I turned on the engine in the morning and it died after 10 seconds and I was unable to restart it.

The only thing that stands out is the 5 yr old battery died as did possibly the lights that illuminate the temperature controls on the center console. My aftermarket car stereo has been turning off and on for a second or two almost on a daily basis for the past year but I’ve had my system for close to 10 years so the problem could be that the head unit is old.

Like I mentioned I've had this car for a while and I just need it to work for another 4 months until I start a better paying job so any help would be much appreciated.

There are many threads about the main relay going out. Try searching for that.

Like I said I recently changed the main relay and those symptoms are different then what I have. As it turns out the distributor was the culprit.

Ah, yes you did. Sorry about that. Good thing you figured it out though.

that happened to mine. Did the relay and it was good for like 6 or 8 months then started acting up again. Then did the distributer and its all good now. Does your tach go all crazy when you floor it? You say you did your ignition already so Id replace that relay.
