is there any extra steps you need to do on a k20 swap on a 2000 itr green key factory immobilizer? lacking fuel pump power and crank.


do i need to do something to the ignition ?

 

if you have kpro I believe it shouldn't matter

 

give us more info on your setup and how everything is set up and we will take it from there.

so what motor is in your car? do you have a swap harness? what year is your car (2000?)?

do you have k pro? etc...

 

its a k24/k20 head, it has a k20a2 02-04 harness, a charge harness, hybrid racing harness, 2000 integra type r, kpro.
the main relay wasnt getting power either but i have swapped the chasis harness to a 98 gsr chasis harness and now the main relay does get power but still no fuel pump/crank, have tried multiple main relays, all fail

the swap came out of a running eg

and just a heads up, i figured it could be something to do with the green key ignition which is why i posted it in the itr section because obviously if that does have something to do with my problems it would not concern 99% of the other k20 swap cars

 

Imo.. it most likely has to do with the plug n play harness.. the wiring for the itr which i also have is a tad bit different than the eg. contact hybrid have them send you schematics for the harness and let them know its from an eg and you have a 00 itr they will guide you from there..GL

 

the hybrid harness is for eg/dc though, i got the hybrid harness seperate and new and followed the hybrid instructions for install, twice

 

Shoulda kept ye ole B series :p

 

a b series just isnt going to cut it, my stock r motor did 194whp, my built r motor did 230whp, and those are fine for my beater civic, i guess

 

What class or organization are you racing in where the 230HP R wasn't enough?

 

He's in a class of his own.

Did you ask in the hybrid forum or a forum that is more specific to K swaps? They should be able to provide more help.

As well, I'm not sure we should post up any kind of solution to defeating the immobilizer--no matter how obsecure it is.

 

I had the same problem and it was a grounding issue. I used a dremel to grind away any paint on the chasis that had a ground. I also grinded the surface of the grounds both where it connected to the motor and chasis and it fired right up. Theres alot of corrosion that builds up on the grounds especially the tranny ground. Give it a shot.

 

go thru the kpro with the laptop, and check the settings. make sure the immoblizer is turned off on the k-pro this could be the cause of your problem

 

its not built for any racing class, its made to go fast, turn fast, and sit in my garage


will continue to work on the ground points and will look for a cable to connect the ecu to my computer

 

3 things that could be helpful to you.

1. Fuse, under the dash, it could be number 25, 30, 31. Check these. If one of these is blown, your car will not start. I spent 4 hours in my ek taking **** out just to figure out this was my problem.

2. Reload your Kpro map. Sometimes this can be a problem. I know it doesnt make sense, but happens.

3. Fuel pump relay clicking?

4. Sand your ground points down, and watch the valve cover ground point. do not do it from the valve cover at all, but instead on the vtec sil or the timing cover.

If none of these work, make sure your starter wire in the charge harness is sending correct voltage. Could have a short.

 

If you are using a JDM K20A ECU you will need to hot wire your fuel pump to a switch.

 

Gil, would that rule go for the Kpro?

 

I believe so. I remember Jeremy had the same issue with his ITR and had to have the furl pump on a seperate switch. It would probably be best to call Hondata and confirm.

 

interesting. thanks for the info gil.

 

adding to what gil said when i sawpped my K into my 00 R i could not get the fuel pump to prime either. i had to ground the fuel pump switch to the chassis and it solved my problem. it was the fuel pump wire and it was not getting the sufficient ground that it needed till i made a separate ground and bolted it to the chassis.

i can take pictures if you like. hope that helped.

 

that would be fantastic, are you talking about a ground coming off the plug for the fuel pump wires or one off the b series engine harness plugs, or k series engine harness?

either way, motor is out of the car, mounts and other misc are being powdercoated, hoping to finish off the bay and painting the bay before it goes back in but we will see,

thanks for all the suggestions

i may be back
