Back to the begining, must be the inj or ECU tune if fuel connections OK.

Have the Inj been recently flowed or tested for thoughput - I left mine on bench for two months and would not work as gummed up inside.

Are they ticking or actuating that you can hear with a screwdriver on them on your ear? Check plugs for wetness of fuel in each cyl if unsure.

Maybe ROM tune is out in timing or fuel maps on start.

Are you getting any error codes from ECU?

NewKleer's LCD Consult just diagnosed my problems via datalogging software that told me the timing was advancing to 60' BTDC at 3000RPM on the road.

Hold a screw driver on the injector and listen to see if its ticking when cranking, if it is then its a fuel supply issue. Take the fuel feed line off and make sure it purges when on reders. Does it attempt to kick at all? If it does not then I would assume the injectors are not firing what so ever which should indicate a wiring or EC tuning issue as already suggested.

Have you used the correct impedence injectors right? Also after cranking can you smell fuel?

If you can smell fuel than it may be another issue entirely like spark.

The AAC unplugged wouldn't cause the car not to start though.

Maybe start then stall if its adjusted incorrectly but nothing a little press of the accelerator couldn't get going.

is that cause AAC is normally open (and therefore ull get a really high idle is disconnected?)

The idea is to set the aac valve so that idle is 650rpm (R32) with the plug disconnected, with the plug connected (solanoid) its used to raise idle when needed (powersteer, a/c & prevent stalling etc)

The solenoid shouldn't be relied upon to get you your 650rpm as this is when hunting occurs.

If its wound all the way in and the car won't idle the car will still start but stall.

      V37 Radiator removal

      By Duncan · Posted

      So, this shouldn't be such a mission, but there were a few tricks so I thought I'd post up a DIY for it. This was on a Q50 Red Sport but I doubt any other V37 model is very different (maybe just less steps for the intake heat exchanger hoses) I pulled the radiator out to flush it because the car was running hot at the track, but obviously the same steps apply for changing a radiator for any reason including an upgrade. If you are removing the radiator, you of course need to drain and refill, so have 5+ litres of blue coolant ready. You don't need to drain the intake heat exchanger to remove the radiator but depending on your plans you may need a couple of litres for that as well. You will also need something to deal with the auto transmission lines, I used 2x 8mm rubber caps on the radiator side, and a short length of 8mm pipe on the car side.....unless you can block these lines quickly you will loose AT fluid and it may be enough to hurt the transmission if you don't refill it. Other than that....lets go... "First, jack up your car". Yes really, and put it safely on stands. If you are not confident doing that you need to give this job to a mechanic

      If the forester is anything like our old 2007 GTB Liberty, I could near on run ling Long's and "rate them", as no matter what, it just hung to the road, even when abusing it in a hard launch in the wet, or throwing it at corners.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
