R33 Gtr Running Lean

[Hot33r8723]

My gtr runs lean on the front 3 cylinders what can be causing it to run hot and lean could it be the exhaust sensor

[Hadouken]

the fact that you havent gotten it tuned and your going to melt another piston

[Hot33r8723]

Yes What do u think it is injectors manifold sensor

[Hadouken]

go and get it tuned. Or just keep melting pistons your choice

[Hadouken]

wait. Are you running that f**ked fuel pump?! Stock 33 GTST injectors? and upped the boost again?!

[Hot33r8723]

No fuel pump is fine standard rb26 injectors

Assumption much?

What afr's is it running? What makes u think its running lean?

Have u checked fuel pressure and flow?

[Hot33r8723]

Running lean in front 3 cylinders

[Hot33r8723]

Havnt pressure tested the fuel pump yet sounds like its priming up ok

[Hadouken]

Good luck with that engine. Might as well buy another one.

How on earth you can be at the point of diagnosing not just a motor running lean, but running lean on the front 3 cylinders, but unable to ascertain why is beyond me...

[Hot33r8723]

Blah blah blah blah

[marksuxass]

1st, test fuel pressure, but more importantly FUEL FLOW. Make sure the earth is ok for the pump.

Cheers mate bought a new Walbro pump

Gonna set it up sweet as

[Hadouken]

Still need a tune. Cant run a RB26 in a gtst with a walbro and not get it tuned. What ecu are you running? Running 1 bar boost? Sweet as, take it around the block again. Turned out good last time.

U should put a relay to up the voltage to the pump. And be sure to earth the pump aswell

Oh BTW how did you come to your diagnosis that the front 3 cylinders are running lean? Reading the 1st bank 02 sensor's i spose?. You sure you 02 sensor isnt faulty if soo (seeing as how most wont last 40,000kms).?
