and my fuel economy is ****!!! but i guess its all part of the same problem.... AF's are hovering around the 10:1 mark

Your AFs are not helped by that Blitz ECU of yours; I assume it aint tuned for australian el'crapo fuels, aggressive maps aside.

Go buy an e-manage.

Go buy a fuel regulator. :D

Just switch the key to on and the pump will pressurise the line, you should be able to heart the pump work then stop, then you can start the car.

The new pump will have more pressure so when the other would not pump enough at high revs this one will be consistent, get it remapped and it will be fine.

if you had your car running fine before installing this pump,then i think youve done something that you shouldnt of.

The pump itself should be ok if that was the only thing installed.

Even if higher flow,the regulator is the part that controles the amount of fuel pressure your injectors will see,and will keep it at a constant 40-45psi at idle.

unless your regulator is faulty,it could raise the pressure and make it run richer(but you havent touched it,have you?).

Best thing to do is,put a fuel pressure gauge in line with your fuel out hose and see how much PSI your getting,and let us know.

Have you connected everything properly?(in -out lines)

once started,can you rev it and keep it idling

explane a bit more...

once started the car runs like an absolute gun!

no idling or fuelling problems at all

its just on start up that it wont start straight away, you turn the ignition and it ticks over for about 5 seconds then fires......

i know i need a remap as well but i cant afford it now as i just spent it all on the pump and a boost controller!

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
