Default coil location

ok so this is gonna sound really retarded but where the heck is the 4 pronged coil pack thing that has to be deleted (not the coil on top of the plug, but the part that has to get pulled out for good, and bypassed)? I can't even find it... might be under the manifold or something? Wires run up towards the center top of the engine, then just disappear!

This may sound silly but when you unplug your old coils make sure you label the wire harness which is what cylinder 'cause all the wires have the same color. I made that mistake and it took me a good hour to figure out why the motor didn't start ;/

Default wrx ej20g--coil conversion--hell--back again

well, my right side coils are not firing.

when looking at the wires on the big plug coming off the ecu, there are like 8 wires, four of them are skinny, and the others are fatter. with the power on, none of the skinny wires have any power to them (200MV) is this right?

http://picasaweb.google.com/evankanga/WRXWestfalia#5317318549881295010[/IMG]
above is a picture. the wires on the left by my fiinger are the fat ones, and the ones on the right are all skinny except one 12V yellow wire.
http://picasaweb.google.com/evankanga/WRXWestfalia#5317318553114166306[/IMG]
this picture of the ecu shows the groups of wires. the four on the right are all fatter, and the four on the left are all skinny.

not really sure where to go from here.

any ideas

thanks evan

Default update--

thanks for fixing the pics.. and by the way i did the coil conversion last year.


all pigtails to all coil packs have one 12V wire, and one that has XX MV[trigger]

how do i check to see if the trigger is working?

i can unplug the pigtails on the right bank and no change whatsoever.
injectors just checked and cleaned.

i am amazed it runs on two cylinders so well.

bad ECU?

ok... injectors:
with the ignition on
#1 12V 9V
#3 12V .2V
#2 12V 2V
#4 12V .4V

with the ignition off:
all read below a volt.

does this warrant concern? seems like it does.


getting someone over tomorrow to help me check spark

Default Update

ok....

i had the wires for the injectors and coils backwards for the right bank.
after changing them .....

i have squirt on 4, and spark on 3

much better... but i am still down one spark.\

on that one coil... how can i check whether i have a good coil pack via the ohms test or another.

I don't know the proper resistance for a late model coilpack offhand, but check it versus the other ones, they should all be almost identical....... also, try switching the coilpack to another cylinder and see if your problem moves.........

Default FIxed

well..... it's sorted....

here's the scoop.

i crossed some wires..... ran some jumpers and found out that the pigtails off the new coils were all correctly inserted into the plugs except one.. which was reversed. re-inserted the wires in the plug and off she goes.

all 4 squirt now and all 4 sparky is the current deal.

thanks again NASIOC

Got mine wired in this weekend. I had the connectors from an 07 Sti sitting around so I hard wired them on to the 20G's engine harness

DO NOT USE STI EJ257 PLUGS ON YOUR EJ20!!!!!!!!!!!

You need to use the 07 coil packs with your regular EJ20 plugs. EJ257 plugs are longer and your piston might smash right into them.

I know better than to use the STi plugs because of how long they are are inside the head. I just used regular old NGK BKR7es. Kbahus used the same coils andit worked for Him I, don't see why it won't work for me. Forgot to mention this is a 2.2t/25d Heads wired as a 95 wrx

Edited above. Said plugs, meant connectors

i just finished my Conversion. more than 100% happy. my car has no problems anymore! awesome thread.

instead of soddering though, i bought some .110'' connectors and sodderd the wires to them and then just plug'ed each one of the 3 into the coilpack. then put the high temp epoxy in. looks awesome and alot easier than trying to sodder inside the coilpack.

Does anyone know the testing procedure for the newer 02+ WRX coils? I am starting to think that i may have a wiring issue from the coils to the ECU.

Just did the convertion and now the car runs crappy. starts well, shakes more than it should, when i push on the gas, engine goes down a bit then rises in rpm. my boost guage indicate the proper boost(11ish psi) but feels like a pony, any clue?



***edit*** didnt expected to have a faulty coil, replaced it and fixed my problem

I got a set of 3.0 b9 tribeca coilpacks for super cheap, will they work the same as the wrx versions? They look the same as the wrx coils but the boots are red. I have a 97 ej20k and will be converting it to coil on plug.
