Great video! Just a word of caution though, I bought a brand new OEM Honda set off eBay for $60 and they were 5-volt injectors. I'm glad I tried to start the car before I did the resistor delete. Otherwise I think the 12-volt would have fried the new injectors. Better to crank the car and see if it starts before doing the resistor delete just in case
Well this ended up being a disaster. The fuel injectors I chose where the wrong size! Lol had to clean the old ones and put them back in, and reconnect all the wires!
I'm not modding anything but I've replaced the ecu already. The problem is I have no injector signal to #3 cylinder only. I'm down to either the harness or the resistor. How likely is it to be the resistor not giving power to #3 cyl
? I have a acura integra 90 that has a resistor box and I'm reading 12 ohms but the car its missfire I found out that a obd1 dizzi was on that means I have obd1 injectors on a stock obdo ecu ? Can I delete the resistor box or its better to get some injectors?
Hi, I have same accord with 1.8l engine non vetec in Uk. Can you help me on injector replacement as mine accord is very bad on fuel and mechanic told me to put new generation injectors with multi spray pattern as original are single port spray?
So, just to confirm, you bought new fuel injectors and they were 12 volt instead of 5 volt? Is that not strange that Honda would create different voltage fuel injectors for the same vehicle? Oh, thanks a ton for posting this video - really well done and super informative.
Most fuel injectors are 12vdc, but yes, for some reason, Honda installed a resistor to drop the voltage to 5VDC for their fuel injectors, so if you buy AFTERMARKET fuel injectors for the accord you will need to delete the resistor - you should also get a tune. but that is hard to do if you don't have an upgraded CPU
@@MyLooneyBin Thanks for the quick response. Wow, that's just so crazy that they would do that. I ended up going to the auto wrecker and I found some 5vdc fuel injectors that all checked out from an ohms perspective. I'll test and clean them and install them. Thank again for your help.
Does removing the fuel rail give better access to the fuel filter? I’ve been wanting to change out my fuel filter but its buried behind the fuel rail (at least thats how i see it).
I gave up replacing my fuel filter, you need the claw foot wrenches with an extension, but I could never get mine to break. maybe with the car jacked up and one guy above and one guy below, but as soon as it breaks, the guy below is gonna get drenched! If you figure out how to change it, PLEASE let me know!!!
@@MyLooneyBin I got it loose I just had to spray it with penetrating fluid for a couple days prior to taking it out someone recommended soaking the fittings in a towel soaked with the penetrating fluid and that’s seemed to help was able to get one side loose, the other side I just unscrewed where the fuel line goes from the filter to the fuel rail and took it to a bench vise and was able to get the nut loose using a breaker bar and a pipe on the end of it
No. Should have had fuel leak as you were taking off the fuel rail! All good. Just make sure you have the proper size injectors for your setup. Very important.
I have f22b2 accord can’t identify misfire issue due to missing wiring from the OBD reader under my dash. But it misfires and jerks on acceleration and release of gas pedal at higher rpm. Also now consumes about 5 times the amount of gas it should and smells like fuel in the cabin. It has a eBay cold air intake and aftermarket long tube headers and no tune could that cause air/fuel ratio problem? So far I’ve changed spark plugs and wires, it also has exhaust cut up to the catalytic converter. So now I’m down to either I need new injectors, fuel filter or pump, or even just my cat is clogged from having no exhaust? It runs and drives just misfires and backfires loud sounds cool but I know my motor is just screaming in pain. Someone help please thank you.
could you have a timing issue? possibly try rotating your distributor a little to mess with the timing just a little, but ods are you might be off on your timing a little? unless your throttle body is messed up??
@@MyLooneyBin i think low impedance is 3 ohms and high impedance is 12 ohms. I think with the resistor box and low impedance for oem 95 accords. I think. Not 100 percent sure but I do know the ohms are right since I use honda tuning suit to tune my turbo 95 accord. And my injectors are 12 ohms without the resistor box.
What size injectors did you use? I have JDM h22A swapped accord and I want to change the injectors. The car still has the resistor box. What size injectors do you recommend?
@@RenzSantiano yes. If they are after market injectors they are most likely 12vdc. The OEM voltage on the Accord for that year was 5vdc so you would need to delete the resistor. With a 420cc injectors you will need an after market intake and the best spark you can get. 420cc is a lot of fuel for a standard setup. It probably won't work.
it is a 1994 honda accord with NEW injectors - these are NOT OEM injectors, these are aftermarket injectors. Most after market injectors are 12vdc, the 1994 accord had a 5VDC injector system, so you have to delete the resistor to bring the voltage up to 12vdc
Too much fuel. Didn't have enough air or the proper tune. Didn't even have enough power to get out the driveway. The fuel.injectors I got were too big! Too much fuel. Not enough air and spark
Probably. If you are using aftermarket they are most likely 12v. You need to do the resistor delete. Just do it in a way you can change it back if you ever want or need to. Also if your injectors are too big the car can't ignite the gas.
@@MyLooneyBin I also checked the ecu because i was suspicious of that before i changed the injectors, and i noticed some burning on the inside on some soldering where the connector port is
@@angelsaninocencio6055 nice, I did by the prelude P12 ECU I planning on upgrading to, but I have not looked at mine yet, I will have to check that out!
I’ve also cleaned fuel injectors and egr passageways they were full of carbon buildup, but made no difference still misfires. I wanna fix it before I cause further damage as she is my daily A to B…
I am pretty sure the old injectors work off 5VDC, but I guess all you would have to do is meter the voltage coming out. I guess OHMS law is the answer, but either way, you have to delete that resistor that drops the voltage.

Thank you! This was the most simple and to the point resistor bypass video I’ve seen! I will do this on my turbo accord build
very nice, I am looking for a manual transmission, but this one get's me back and forth to work. It's a fun car to work on
@@MyLooneyBin I actually won’t do this haha I’m just going to get dsm 450 injectors instead! Oh yeah the manual is great man you should get one!
Great video, excellent instruction!
Thanks!
Thanks for this. Gonna change the injectors on my 97 civic
good luck man, let me know how it goes, make sure you don't go too big until you get the air flow to support it!
This is great!
Thanks man!

Can I get the link for the 5 v injectors
I have never felt comfortable working on machines and am always surprised when things go well.
Well this ended up being a disaster. The fuel injectors I chose where the wrong size! Lol had to clean the old ones and put them back in, and reconnect all the wires!
@@MyLooneyBin What's up with the throttle cable going over the PCV hose toward the end? Shouldn't it be going under it?
The filming could've been a lot better, but hey; ya caint get a good one all the time. 😂❤

@@merlin3921 thanks, I am glad the video helped ... thanks for commenting!!
What injector brand do you recommend ? there's so many to choose from
Can a F22A1 motor from an 93 accord work nd run in a 94 Honda accord 5speed nd or if theres a video link u can comment for my info
Does removing the fuel rail give better access to the fuel filter? I’ve been wanting to change out my fuel filter but its buried behind the fuel rail (at least thats how i see it).

@@cblizay1165 that's awesome. Great idea. Never thought about leaving part of the line connected and just change it when you get it out!
Do you have to release fuel pressure before taking out fuel injectors. I didnt do that. Will my engine be fine?
No. Should have had fuel leak as you were taking off the fuel rail! All good. Just make sure you have the proper size injectors for your setup. Very important.

I was told that when removing the resistor box you need a ecu that doesn't look for a resistor box or it will burn up the ecu down the road?
I have not hear that ... interesting, because the resistor box is just taking it from 12vdc to 5vdc? I will have to check into that
@@MyLooneyBin i think low impedance is 3 ohms and high impedance is 12 ohms. I think with the resistor box and low impedance for oem 95 accords. I think. Not 100 percent sure but I do know the ohms are right since I use honda tuning suit to tune my turbo 95 accord. And my injectors are 12 ohms without the resistor box.
your honda sounds like our old 99 ford
yea, that' s not a good thing!
What size injectors did you use? I have JDM h22A swapped accord and I want to change the injectors. The car still has the resistor box. What size injectors do you recommend?
I will say this, with no intake or exhaust mods, 420cc were too much! so, i went back to OEM injectors until I get a larger air intake
For 420cc injector do i need to delete the resistor? Thank you
@@RenzSantiano yes. If they are after market injectors they are most likely 12vdc. The OEM voltage on the Accord for that year was 5vdc so you would need to delete the resistor. With a 420cc injectors you will need an after market intake and the best spark you can get. 420cc is a lot of fuel for a standard setup. It probably won't work.
Okay thank you. The idle is rough like almost died. I’ll do the resistor delete then.
@@RenzSantiano let me know how it runs. It was too much fuel for mine. I had to go back to stock injectors until I can upgrade the intake
sorry if I'm missing the info, what year are those new injectors?
it is a 1994 honda accord with NEW injectors - these are NOT OEM injectors, these are aftermarket injectors. Most after market injectors are 12vdc, the 1994 accord had a 5VDC injector system, so you have to delete the resistor to bring the voltage up to 12vdc
Thanks, how do we know that the aftermarket are 12v instead 5v? most aftermarket parts here doesn't came with these info.
have you got any problem since? (with the injectors)
Did this give you a noticeable difference in power?
Too much fuel. Didn't have enough air or the proper tune. Didn't even have enough power to get out the driveway. The fuel.injectors I got were too big! Too much fuel. Not enough air and spark
What happens if I do this on stock injectors after cleaning them?
can not do a resistor bypass with stock injectors.... it will definitely mess things up stock are designed to run on 5vdc, this bumps it up to 12vdc
Can I do this on Auto 95 Accord EX ?
yes, but remember, you will need more spark for this size of injector, and most likely you will need more air as well
I just changed mine but i havent done the resistor delete. It cranks but wont start. Is the resistor the reason for this?
Probably. If you are using aftermarket they are most likely 12v. You need to do the resistor delete. Just do it in a way you can change it back if you ever want or need to. Also if your injectors are too big the car can't ignite the gas.

did you try the high quality platinum spark plugs?
I see you did change the spark plugs
I just changed my injectors and did the bypass and now it won’t start
What size injectors. Need air, spark and probably a tune. These cars are about 220cc. It takes more to make the car work with 420cc injectors.
I thought it's 5 ohms not 5 volts.?
I am pretty sure the old injectors work off 5VDC, but I guess all you would have to do is meter the voltage coming out. I guess OHMS law is the answer, but either way, you have to delete that resistor that drops the voltage.
