You can get a relay here: www.ebay.com/itm/OEM-MAIN-FUEL-PUMP-RELAY-RZ-0088-90-97-ACCORD-95-98-ODYSSEY-PRELUDE-CIVIC-/291948138436?ssPageName=STRK:MESE:IT

If your Honda Acccord, Prelude, Civic, CRX, Odyssey, or Acura isn't starting, your fuel pump main relay is most likely bad. It is probably not the fuel pump. How to test the fuel pump relay : Turn your key 2 clicks just shy of turning over the engine, you should be able to hear the fuel pump prime. You should be able to feel the relay click twice, once for each position of the key, as you turn the key, and it will click a third time when you turn the engine over. A bad fuel pump relay in your Honda will cause the car to run intermittently or not start at all. The car runs and then shuts off or runs and then won't start again once warm, etc. The Prelude, Civic, CRX, and some Acura's use the same RZ-0088 style of main relay usually made by Mitsuba. The color or number may be different, but the relays are very similar.

      2004 honda accord lx main relay where is it located

      noticed you didn't install relay so don't know if that was problem or not. and you didn't try to start car before and after relay issue so noway to confirm relay was real problem. maybe it was muffler that needed balancing thats why it was blocking gas from tank and sending fuel to left turn signal which caused fourway flashers to pause into twoway flasher canceling out the spark to ignition of atomic thrusters.

      My Honda Accord is misfiring at iddle it does ok at higher speed. Car now struggles to start. Could this be relay, fuel pump/ filter, or fuel injectors?

      I would start with checking the distributor cap/plugs/wires, or the distributor itself

      Car dosent wanna start when its even slightly warm.
      I can hear the fuel pump prime, but it dosent stop like it should after 2 seconds, it just keeps priming until I try to start it, once I stop cranking, the fuel pump will turn on again non stop.
      When its cold car starts fine, but when its warmed up, it dosent wanna start anymore.
      You think it might be the main relay?
      It gets spark and I could hear pressure in the fuel rail.

      @Henry Lima If it keeps priming it might be sticking on, and if that's the case, it could be acting up in other ways. Maybe there's some other wiring issue as well, but I'd start with the relay personally.

      @a DIY Car Guy so even if the fuel pump primes it could still be the main relay?

      Well the main relay is the easiest thing to replace and rule out so I'd start there.

      Hi, in my car, a honda Civic now replaced a new fuel pump and got another AC pump relay, but unfortunately there is still nothing! I turn the key and do not click on the relay and the pump does not go but if you think of a car then it starts, there is a click and the pump goes. would not receive AC power from the relay ?? what should I look first of all?

      that relay got involved into it though,oh I do not know it now that into my type That one 1992 Honda Civic Vtech 1.6 gasoline types,that this head relay is possibly yet in it? because the ac does not receive current altogether certainly on all of them relay,you are though ECU could have got ruined?

      so far it is only started when he felt like it, almost always first cold, then hot longer, and now has been absolutely will not start! no se ac relay clicks, no pump ac hum! I did not do anything to him, this phenomenon itself was about three days ago.

      Did this but still won't start (worth replacing tho, as mine is an 02 Accord, so the relay was 15 years old). Just like in your video, I'm getting starter but no fire. Could it be the ignition switch, or the fuel pump itself?

      Interrupted by storms today, but I determined:

      1. The distributor turns when car is cranked
      2. There is a spark at the spark plugs
      3. I can hear the fuel pump prime when the key is turned to on

      Going to check for fuel pressure if/when the storms clear.

      a DIY Car Guy In reply to GoalieLife

      I have lots of ideas, here are some: I would check for fuel pressure at the rail and check for spark from the spark plugs. I would put 12v right to the pump while it's out of the tank to see if it even works if you got the junkyard pump. Someone told me they can explode so do it at your own risk, but I let them dry for a day before testing and never had a problem, take safety precautions like glasses, shield yourself behind something, etc. anyway. Have someone go near the gas tank as you turn the key and see if they can hear the pump at all. Could be ignition switch, but if you're getting power at the pump I don't think so. If there's a check engine light on, get the code.

      a DIY Car Guy In reply to Jorge Caldas

      Hi, I don't think that would be the relay, I would look at the distributor, or the coil itself might be bad. You can do some type of test on the coil but you'll have to look it up for your specific coil

      if the relay is the problem and the car won't start does the fuel pump still buzz before you turn the key all the way to fire the car up?

      about 2 years ago
    • a DIY Car Guy
      a DIY Car Guy In reply to Jesus Mungia

      Sounds like the relay is still working and providing power to the pump. The pump might be bad or there might be a bad ground. I would test the voltage at the pump, and / or the fuel pressure at the fuel rail. If the voltage is good, but the pump is buzzing and not pumping, then I would replace the pump.

      After putting back in starter and everything tightened back up I put key in turned it and it started!!! Yes!!! I didn't want to deal with new ignition switch 5 different part store to find sheer bolts! Now I have couple sheer bolts I'm stuck with.But I can return the switch! After all that it ended up being a stuck starter! It's freed up now and fierd right up! Thanks again

      I don't think a 97 would have this relay. You will have to plug in an obd2 scanner to find out what's wrong, if there's a check engine light on.
