Hey I have a cheap osias FPR for my ek k swap hooked it up to stock fuel filter on the left. right side goes to stock z3 fuel rail and the bottom is hooked up to the return line. So my question is that I turn the key to the rdy pos and it primes the pump and I get about 45-50 psi but if I tighten the hex bolt on top. it doesn’t adjust psi and if I back it almost all the way out doesn’t move still. Reason being I’m trying to get my k swap started but it sounds like it’s not getting enough psi engine putts alittle bit and some times turns one for a second and dies.

 

45-50psi is plenty of pressure bit make sure you you have the regulator plumbing correct. It's possible you are not sending fuel to the fuel rail.

Immobilizer also comes to mind.

Will it stay running if you spray non chlorinated brake cleaner in the intake?

 

Man you are all over the place on this thing.

That FPR has garbage reviews. Most are saying it does not adjust. Sounds like you have it connected correctly, side ports are supply and rail, bottom port is return. The pressure you have should be enough but that is still a garbage FPR.

You never resolved your immobilizer issue in the previous thread. This is likely the immobilizer. The K-tuned bypass specifically says 01-04 on the PCM.

 

when I spray starter fluid it does turn on for alittle bit longer. And ya I’m struggling right now. But I think I got the imobilizer to work. I had it wired the way they showed. And it just cranked. Then I swapped the multiplex wire to the correct pin out and then it started puttering. But you still are probably right. So if there’s no bypass for this what am I supposed to do if they don’t sell any bypasses

 

Get a supported PCM or swap in all the required pieces to make the immobilizer function.

 

what’s a pcm? Ecu? And that’s another thing I’ve been searching for so long know they only stuff that pops up for the imobilizer for a 05 ecu is the ktuned or hybrid racing ones. Thanks for your help also dude I really appreciate it

 

PCM, ECU, ECM, all the same. Changes a little by generation and if automatic or manual but that's getting nit picky.

Powertrain Control Module is what modern stuff is called with an automatic. Powertrain including engine and transmission.

Engine Control Module is mordern manual transmission. Doesn't control the whole powertrain just the engine.

Engine Control Unit is old school automatic and manual. The real old Honda stuff had a separate transmission control unit for the automatics.

 

Ah ok makes sense. Any thought on how the hell im supposed to bypass the imobilizer. I searched the website I don’t see where it says 02-04 ecu unless I’m blind haha

 

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

 

Congratulations. Can you post the ECU pin locations that you used (and what wire you connected to each) so others can follow how you made this work in the future ?

 

of course. I just swapped the around the 02-04 with the 05-06 pin locations. So swap pin 1 to pin 17 for fuel pump and pin 24 to 13 for multiplex

and I also as for the fpr it’s a cheap on so Ryan was right it’s crappy and doesn’t adjust but it’s working so I’ll leave it for now.
