apologies if this is in the wrong location, not sure where to post this.
My Rb25/30 in my vl refuses to start.
Was previously running as a single t3 setup, moved to bigger hotside now wont start.
Car currently cranks but gives no hint of starting.
Have checked the following:
Has Fuel - Have gone as far as removing injectors to ensure that each is firing.
Has spark - have removed all 6 coil packs with plugs in and have seen spark from each, looks quite strong.
Has correct timing - both cam gears line up with markings as well as the balancer is lined up. Even removed the intake cam cover and ensured that the 1 valve is pushed down at the moment of TDC (had originally had it 180 out but this has been fixed)
Has Air - removed cooler piping, just straight opening from the TB.
Has compression.
Things I have tried:
- The old start ya ******* in the intake, still no sign of start.
- Fuel directly in the cylinders, still no signs.
Is run by a Wolf ( please dont suggest that I should bin this, was working previously)
I appreciate if anyone has any other suggestions for me to try? I am all out of ideas.
Need anymore info let me know!

So you have compression, fuel & strong spark. You say timing is correct.
Firstly make absolutely sure there are no leaks between the AFM/turbo/intake. If everything you say including timing is correct then it must be either too much or too little fuel. Seeing as you have sprayed "extra fuel" in (the start ya *******) and still no go, that points to being way too rich. I'd make a bet you get a strong fuel smell out the exhaust after cranking it for a while.
You could try this to confirm there's too much fuel. Either unplug the injectors or disconnect the fuel pump fuse and depressurise the fuel system. If you do this by cranking then make sure you crank the motor enough to clear the fuel out of the cylinders. You should probably check the spark plugs arent fouled at this point which is pretty likely if it's running so rich that it wont fire even once.
After all that then get a buddy to crank the motor while you spray a decent amount of start ya ******* into the intake... if you have adequate compression and spark then you should hear it fire a couple times at least.
Then you just have to find out why its so rich. Also what size injectors you running? If you've got a new ecu and injectors and havent had it tuned well there's your problem. If still no go after all that i'd bet my life savings that your timing isn't correct. It's easier then you think to mistake it and just a little off timing will **** the whole cycle.

Hey mate tgabks for the reply
Finally got back home to work on the car. Car has been sitting for months so defo not fuelled up. Unplugged inj / fuel pump and cranked with start ya ******* and no signs of life.
Just tearing down to triple check timing now.
I don't have std inj / ECU available to me ATM. If they are the issue, would the car at least try to splutter if everything is ok? I just don't want to take to a tuner to discover there is something wrong...
