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?

      Question about BoV on RB25DET NEO

      By Murray_Calavera · Posted

      You've just discovered a really good reason to tell yourself, yes, I do need to buy an aftermarket ECU. Put the MAF in the bin. Slap in the new ECU and have a think about what turbo sounds you prefer.  Do you want a 90's style BOV wooosh? Do you want a hektik tsututututu?  Mate, can't go wrong. Just gotta get that ECU and the world is your oyster.

      Question about BoV on RB25DET NEO

      Hi. Iam just curisou about this topic. I saw this video. It is about Greddy Type FV2. I know that BoVs are about that sound but how and when to use it? I read some topic here and from what i have understand on stock RB with MAF there will be some "problems" if you use this BoV? It vents the air in to the atmosphere and the MAF on stock car needs this air back in to the intake and not out? Or is it wrong? If so...i saw you can put some adaptor to circule air back...but does that not "loose" that sound? I saw another BoV from Turbosmart and it has two "exhaust" like ports? One is for the stock tubing for letting air back and one is for "sound" and let the air in the atmosphere? Can someone please explain? This is the Greddy one:  And this is the Turbosmart.     THANK YOU!! EDIT: So i read about this topic some more and i if i understand that correctly: That Greddy can function either like BoV or 100% Bypass valve? And that Turbosmart is what they called hybrid so you can adjust what and how many air can be vented out or back in? Is this right? THX!

      That dirty voltage drop is the culprit I suspect

      It's about time I start work on my sun tan. So I knocked up a few parts that will all combine together to become my new power steering reservoir. Now just to produce an abundance of UV and IR rays while melting a heap of bits of alu to become one... Well, that's after I put one more hole in it for the return line to plumb to. It likely won't be this weekend, as Sunday I'm meant to be in doing some last minute stuff to the AMG race car, and the weekend after will be filled with non my Skyline stuff, followed by Bathurst 6 hour. So I don't expect to get to melt metal for at least 3 weeks.   I also managed to stuff up and start cutting the hole for the res to pump pipe on the wrong side of the line... It means instead of the lines being nice and tight against the inner guard, they'll be out off the guard.    The size of it means I should end up with about 1.8L of power steering fluid, and still have space for another half a litre before it reaches the overflow/breather. This is wayyyyyyy more capacity than factory, which should help keep Powersteer oil temps lower, and the design hopefully allows it to prevent any aerated oil being able to makes its way down to the bottom as it'll have a couple of baffles and some hopeful trickery to force air bubbles away from the bottom.
