In this video I'll be showing you how to test the main relay and your Honda Civic this one is a 2005 I also pull out and check on the air-fuel ratio relay also. I used the headlight relay because of their similarities to check the other relays.The symptom my customer was having is a startup and then immediately dies or cuts off right after. This could be a main relay or an ignition switch.

Thanks for your video, it worked perfect after the relay change

@AM-hv8vc 4 года назад

So what was the problem?

@adinas1542 3 года назад

Solved my problem with no crank no start in my civic 2004, just tapped on those 2 black relays with a hammer while turning the ignition switch on and it did the trick. I was going to replace my starter but glad I tried this before ordering the starter. Thanks.

@okhita 2 года назад

with hammer, lol hahhahahaha

@averyalexander2303 2 года назад

That's weird, the 2 black relays have nothing to do with it starting. One of them is for the o2 sensor heater and the other is for the reverse lights. The blue relay is for the fuel pump and the brown relay is the power to the ECU, fuel injectors, etc.

@dragonmantuning3792 2 года назад

@@averyalexander2303 thanks for this. Are there any other fuel related relays?

@averyalexander2303 2 года назад

@@dragonmantuning3792 Nope, nothing fuel related. The only relays needed for it to run are those blue and brown relays and there's a starter cut relay in the under dash fusebox that keeps you from cranking it in gear or without pressing the clutch pedal. Are you still having problems with it not starting?

@jimmydrakopoulos2140 10 месяцев назад

Hi . I can crank but no start. I do not hear the fuel pump when i put it on ignition. Is the blue relay for the fuel pump? Or brown? I will check voltage on pump and give it a try. I have a start with starting fluid.

@iansingleton1274 Год назад

Just make sure your looking at the circuit diagrams on the top of each relay to make sure it’s the same as the one your replacing

@Glenndulay-k8q День назад

Just replace the relay make sure u put them on the right spot. So on anyone got something to say with any comment what so ever that would not make the situation better please just dont say anything keep it to your self . unless you got diff question .

Hey I got a 2002 Honda Civic but didn't have the keys the person I brought it from lost the keys is there any way to get it started

@luiz6089 3 года назад

The air/fuel relay that's the one controls the fuel pump as well?

@jzila9900 4 года назад

Normally the relays go bad because the solder goes bad after many years, I had a main relay go bad once ,all i did is tap the relay kinda hard at the same time i turn ignition switch on and the car started ,three days later is I bought one for 60 bucks at o riley's at replaced it

@marctrottier8232 10 месяцев назад

i just replaced the ignition switch in my 2010 honda civic and problem solved !!!!! the car was shutting off while driving and hard starts , so easy to change and cheap only $70 , honda is known for bad ignition switches and there was a recall for that !

Honda Civic 7 2004. I have a problem, the battery is discharging. In warm weather loses 2.5 volts in 24 hours when just parked. Decided to check the current, when I put an ammeter in the gap of the circuit, some relay clicked and there was 3 amps of current leakage. But amazingly, when I decided to check the assemblies by removing the fuses, took off the first fuse, which is a 20A air conditioner cooler, the relay clicked, and the leakage disappeared. I put the fuse back in place - no leakage. But miracles don't happen, do they? I couldn't fix the problem by just flipping a fuse, could I?

I have an 02 civic EX ex and I'm having an issue where It will only start every once in a while otherwise I'm having to pop the clutch to get it to start it also is running very rough loss of power unless you are able to push accelerator to a certain position then regains power until it either passes to far or to close from sweet spot not sure of either problem is related but both seemed to start hand in hand any suggestions p.s. just replaced spark plugs and coils maybe a month ago

CAN YOU HELP? I have a 2001 Honda accord 4cyl It's stuck in my garage right now can't start. It turns but doesn't wanna start. I put starting fluid in air filter and it starts and runs for about 10 or so seconds and then stutters off. It's always had low idling issues too. I've had this problem for years but it would always work using starting fluid. Sometimes it would take 2, 3 or 4 tires but it eventually started. It would be fine for weeks or months on end but then have the same issue. But now, after 5 years it wont start at all. I replaced the fuel pump and filter 6 months back. So probably not that. What do you think it could be...? Fuel pump relay or main relay or idle air control valve stuck...?
