Anything is possible but it's highly unlikely..

Your pump should turn off before that happens and fuel will not pass through the reg the wrong way anyway..

You have another issue, you need to find it

Pull your I injector rail out, turn ignition to on and see if fuel comes out of the injectors..cause it shouldn't.

If it does I'm confused why it is doin it..would seem something is wired up wrong or could be as simple as a setting in your ecu..

Reading your other thread that states you have a 26 pfc and a 25 loom (or whatever the f**k you have done) it seems obvious you have muffed something up and your injectors are getting voltage full time..

disconnect fuel pump and test injectors with a multimeter or even just a test light.

Then when you realize this is the problem figure out why....

That should be fun. :devil:

I have a 26 loom and a guy on here used the original 25 loom to make it compaitble with the other stuff, installed injector dropping resistor an all that. anyway have come to the conclusion this is not common and somthing is way effed up and I shall pay a professional to fix my problems :rofl:

Injectors have constant ignition power or 12v at injector with ingition turned on & They earth through ECU.

So put test light on positive battery terminal and check for earth at injector plug, If earthed you have problem!

After Fixing problem, Drain the oil, crank out cylinders, refill with clean oil, add 20-50ml oil to each cylinder, crank over till oil pressure then start.

At least it'll flush the sh#t out after rebuild!

Or a stuffed reg can do this, pull vacuum hose off the reg and see if fuel comes out.

Could make sense, if its running out of a busted reg, it'll run into the plenum, and therefor into the cylinders...

The injectors were plugged in with cas disconnected i assume they are stuck open or receiving voltage

sounds like a wiring issue as the injectors wont leak unless they are opened via ecu. what ecu?

      Rebuilt Rb25det issues

      By KyoyaR33 · Posted

      Howdy all,   I had my rb25det S2 rebuilt and finally started it today but have run into a few issues  Engine sounds like a a diesel easiest way to summarise like small ticking, gets louder when revs are slightly adjusted  The engine builder repainted the engine cover leaving no where for me to go off with lining up the CAS so have it as central as possible so not sure it that could be affecting it?, changed the gearbox fluid too but won’t seem to go into gear when running, and only 1 to 4 when off having a hard time finding 5th and reverse anyone got any ideas or a base for me to start off? much appreciated

      Well, no. It's an 023, which is pretty similar to an 040. Although it is hard to tell from the specs, as given.

      Hmm. Maybe the (other thing I forgot about!) Haltech removes at least some, if not all, of the problem I described. I guess there is still the possibility of getting it wrong if the AC is set up/wired up for the Haltech as if it was in an R34 (simply because it's on a Neo), and that's playing foul with the R32 AC computer.
