I swapped a k20z3 into my 99 civic wired it up with the k tune swap harness and car cranks but no fuel pressure. And I don’t hear the pump.
prob ecu

 

What ECU are you using ?

 

prb ecu from rsx

 

I wired the green yellow fuel pump relay wire from k tune harness to the green yellow on the factory e plug a16

 

Is there a damn immobilizer in the ecu??
how do I know if it has one? 2006 prb

 

Is there a way to bypass it with out buying an expensive bypass. Can I unweld some stuff on the ecu?
I’ve seen some videos of people just breaking them off but idk if that actually works and idk where it actually is on the ecu

 

Bump

 

If you have a stock ECU, then YES there is an immobilizer. Also remember that there are going to be many sensors/emissions components that the ECU is looking for and your Civic chassis doesn't have, so you will be eternally plagued by MIL codes that are extremely difficult to defeat. You need to get K-Tuner for your ECU and this way sensors can be disabled or ignored... including the immobilizer... so you can roll code free.

 

So far the only code that’s up right now is just the evap. But I still haven’t had the car started just ordered a ktune bypass

 

Just installed bypass still no fuel pressure ….

 

I don’t know what I did wrong I have triple checked my wiring and everything is good bypass is yellow to a2 black to a4 and red to e27 and blue to e24 and ecu is 05 so I should have the blue cable installed but nothing

 

I’m using a 2005 harness and prb ecu from a type s with a k20z3 from an 08 civic si

 

The K-Tuned website shows that the immobilizer bypass unit only works on the 2002-04 PRB ECU... NOT the 2005-06. The wiring connections are different on the '02-04 engine harness from your '05-06 engine harness and this is partly why it didn't solve your problem. You need to purchase a K-Tuner ECU upgrade so that you can turn off the immobilizer and any sensors necessary to properly run your Z3 engine in your EK Civic.

 

I just found out that the pins on the e plug from k tuned are set up for a 02-04 I searched up pin out for 05 swapped the e1 to e17 and the fuel pumped primed and I now have 50 psi of fuel pressure. But still won’t start. Are you sure the immobilizer won’t work it doesn’t say a year and it said works with prb.

 

I searched up the correct pin outs for the immobilizer for my ecu and now the car putts alittle longer and almost starts but the FPR reads 45-50 psi but when I go to adjust it it doesn’t move stays the same. FPR broken? But you might be right maybe I just need a chip but it seems like it worked since it sounds like it wants to turn on after swapping the pins around

 

Bump

 

K-Tuned's website states that the immobilizer bypass box works with PRB ECU versions up thru A12. The 2005 PRB ECU begins with version A13... NOT compatible with the K-Tuned device. I suggest you reach out to them directly to see if there is a way to make it work... otherwise, do as I have suggested above.

I think the '02-04 and '05-06 RSX-S immobilizers work slightly differently and this is likely why the bypass box doesn't work.

50psi fuel pressure should be just fine to run the engine. I am not sure how your fuel system is set up, but it may not change pressure at all in some applications.

 

thanks dude I’ll contact them and if it doesn’t work either do a k pro or get the right ecu

 

You will likely need kpro anyway to turn off all the emissions errors you are going to have. Might as well get it now to disable the immobilizer as well.


Oh, hondata also says no 05-06 ECUs.
"The stock 2005-2006 ECU part number PRB-A13 through PRB-A16 has a different microprocessor and cannot have a K-Pro installed."

 

Update
car runs and idles now 😀. I checked to see if I had fuel at the rail messed with the tps. Then started hitting it with starter fluid. Putted alittle then out of no where shot a lot of smoke out the exhaust and heater lines and upper coolant neck. Then it stayed on and idled. Thanks for all your guys help
