Fuel Pump

Can somebody please clarify a few things relating specifically to the r32 gtr. I've done several searches relating to fuel pumps but with all the different models being mentioned in the one thread it gets a bit confusing.

How many fuel pumps does an r32 gtr have as standard? I've just been checking the voltages for my fuel pump and even when I disconnect the fuel pump plug the car still runs.

I can hear another pump coming from under the car and when I re-plug the intank one in the revs increase and I hear the intank pump start humming away.

Incidentally the voltage readings I got were 13.8v across black to red and 8.4v black to blue. I think the blue wire is the one that controls the coil on the relay.

The previous owner told me that the car had a Bosch pump.

The strange thing is I've just had my car dyno'd and made 376hp at just under 1.2 bar but the tuner said he was restricted to that level because he ran out of fuel and recommended replacingf fuel pump or doing a re-wire.

Any help clarifying this much appreciated.

Yeah, I think I was measuring the voltages across the wrong wires. Think they are for the sender unit and petrol light. Going to check again sometime this week.

an r32 gtr has 1 fuel pump, and i recommend you rewire the near on 20 year old wiring

      So whats the deal with the porous block VR30DDTT

      By Duncan · Posted

      Its hard to tell really. The Q50 owner's forum talks about it a lot and has quite a few people directly affected, but no idea what % of cars sold actually had the block replaced. Also, there seem to be 2 distinct issues which both get diagnosed by Infiniti as requiring a block replacement (no wonder they are going broke) 1. "Porous block" where coolant mixes with oil through thin or poorly cast parts of the block 2. Head coolant gallery plugs not sealing. If I was noticing engine coolant loss I'd start with cooling system pressure test (as always) and then I'd pull the cam covers and reseal the coolant gallery plugs on both side before worrying about a potentially porous block.  If neither of those did the trick it would be put in a second hand engine out of japan; I haven't checked pricing but I'm sure there are plenty around by now as they've been in production 10+ years

      To clarify what I posted above, I though you both had a situation where it cancelled sooner one way than the other.....if it is reasonably even where it cancels in either direction that is probably normal (consider gentle movements like lane changes, you don't want it to need half a turn of lock to turn the indicators off)

      Son, in this country, that is a piece of Gyprock. f**king drywall. FFS! I also like the autocorrect of trailer to tablet. I was reading it and thing, "what the hell drugs is he on?" Then the photo made it clear enough.

      SO whats the deal with this issue? I've read a heap of posts from the infinity owners in the US having full engine swaps done under warranty. Most claims are done on earlier cars than 2019 but I'm sure I've come across claims of 2020 models also having this issue. I like the 400r and Q50Red/S but can't fathom dumping close to 50k on a car with terminal issues!!!

      The above video is working normally. That is, that's how the right hand indicator should cancel when rotating the wheel left.
