The car started acting like it was going to die last night when I was parking. It started to sputter almost like it was not getting fuel, I don't think it"s the fuel pump though because when i turn the key to start I can hear the fuel pump start. I went back out and started it this morning and it was still sputtering but when I gave it some gas it stopped sputtering momentarily. After it ran for a few minutes I noticed a strong smell of fuel. I changed the upstream O2 sensor on the manifold thinking that the smell of fuel may have been due to a rich mixture. This didn"t seem to change the sputtering when I started the car back up after replacing the sensor. Any suggestions?
First question is - is the check engine light on ?
If yes you should check it for codes next.
You may have to use a scanner to watch the O2 sensor to figure out if it is too lean or too rich. I would also check fuel pressure at the rail with a gauge to make sure pressure is normal. Could be a faulty fuel pressure regulator among other things.
I took the car for a drive after I changed the upstream O2 sensor yesterday evening and the car started running a little better, I then changed out the other O2 sensor on the downstream end and this morning my car has been running great. This morning my check engine light went off also but only after I had driven the car for about thirty miles and having it parked overnight.
I believe that changing the O2 sensors was all it needed.

Sounds like it could be your alternator dying or dead. Have it checked.

Check the distributor by letting the car run and tug on the wiring and see if the car acts up. Under the thermostat housing is a wiring harness, I've seen coolant drip on the connector of the O2 sensor and cause this problem too. The main relay is the switch you're referring to. It's located under the dash of the driver's side to the left. I've definitely seen these go bad. Use a test light on the hot wire to the fuel pump. Have an assistant turn the key in the "on" position and see if you have power there. Let me know what you found out so I can hopefully give you more things to check out. Send me emails to [email protected].

Sounds like the ignitor in the distributor has gone bad. The cheaper way out is just buying a good used distributor from the bone yard. I've had this same problem several times on these Hondas.

if it's been sitting for a month, then there's a good chance the gas in it has gone bad. Try adding new fuel or fuel stabilizer and running out the old gas.

take off one of the plug wires and hold it next to a metal surface, get someone to turn the engine over for you and see if the spark is bright blue, if it is the coils are ok, then check for oil leaking around your distributor, if you have an oil around that area take off the distributor cap and see if there is oil inside. the seal may be gone, while you have the cap off it would be a good time to check the rotor button inside
