It's behind the driver's side kick panel below the the hood latch release.

having issues with my fuel priming etc for a couple of YEARS and I always thought it was my imobilizer playing up.. after it got REALLY bad and I couldnt start my car the other week, Kyle (KB) suggested doing THIS and it worked - been perfect ever since goddammitt !!

does anyone kno how much a new main relay cost?
for dc2 vtir

ring up Honda.

just did this.

hopefully it works

all connectiosn seemed to be good tho

btu i resoldered them all anyways

lots of black oily shiz :/

I've done this to 2 "dead" main relays and it brought them both 100% back to life.

Bump for the n00bs of Ozhonda.

^^ For sure!

for EG civic, PGMFI relay is behind fuse box, and easyer way to open it is to get pilers onto plastic where the tabs are and bend back, then when done rebend it back and your done ;)

Aim: To get the car running again
Required: 10mm socket, wratchet to suit, solder, solering iron, flat head screw driver.
Steps: not many


so your car starts fine, but after some driving it will stall and wont restart, or restart then stall again, this can be symptoms of the Main PGMFI Relay at fault, as well as other things like coil, ICM, but since the main relay is so easy to fix, why not start there.

A good sign of the relay at fault is you might not hear the fuel pump prime for 5 seconds when you 1st turn on the IGN, ( it can still prime if the relay is faulty )
also low or no fuel pressure.

STEP 1: Locate the main PGMFI relay, you will find it under the dash, commonly the RHS but dont be fooled, lots of modles have them on the LHS, CRV for example you have to remove the glove box. the relay looks like this

STEP 2: remove the relay, there will be one bolt with a 10mm head. unplug the wiring harness.

Step 3: open the main relay, use a flat head screw driver to pry it open, do this evenly from both sides.

Step 4: look for the dry solder joint, if you cant see it just reflow the solder on all the joins, add solder but not to much, allow the solder to melt and bond to the components. reflow the solder on every join, only takes 5 minutes.

STEP 5: reasmeble the relay in revers to disasembly and refit to the vehicle.

thats it !!!

if your unsure of the Main PGMFI Relay location for your vehicle, just reply and im sure someone or myself will tell you.

if you have fixed your relay and still have problems of not starting, start looking at your disributor, eg ICM, Coil. also the ignition switch

Hi how you going ? :D

I would reallly like to know where i could find the main relay in my 5th gen prelude . Dont think i saw anything similar to whats in the pictures of this forum near the ignition switch under the dash :'(

Cheers

its under the drivers side dash, have a good look

Hi guys,

Is this the main relay on a 97 EK civic hatch? Pretty much right under the steering column just to the left of the fuse box on the little bracket.

Apologies for just signing up to post this but was looking for some local advice rather than going on what a lot of the US based DIYs were showing etc.

Many thanks,

Nick

thats not it

look near the kick pannel, it will look like the realy in the first post of this thread

Thanks for that.. I will have a look tonight. By kicker panel I assume the plastic panel on the side of the transmission tunnel in the drivers footwell?

Thanks

drivers footwell
