The fuel did come out a dribble when I pulled the hose off intially after non starting, not pressure sprayed though, this was with engine off and had been off for a while by then though. I did pull off a fuel hose and when I went to ACC with the key, could hear click and pump going and it filled up a jar quickly about 1/2 inch. Was too scared to start car to see if fuel still kept coming - wasnt sure how much there would be. If it was to come out at even more pressure and faster, I would have needed a bigger jar. Does the same amount of fuel still come out as it does on the ACC on position?

Just been home for few checks, So done the usual, started ok, runs for a bit then dies. - I pulled the MAF, started same, ran lumpy and cut out even quicker and CEL came on. Put back in MAF and started and held better / smoother for the 20sec then slowly died. So MAF ok. - I managed to get the connector to the Crankshaft Sensor pulled (below the alternator), tried to start but nothing at all, just the starter motor trying and trying. Put it back in and same as above, started, 20sec held smoothly then slowlydies. So that sensor should be ok if the car didnt want to start at all without it. Think I might have also flooded it a bit with the amount of cranking too, should dry out before Al comes round tonight. You guys with your bets on the fuel pump / filter could be right. Might put in uprated plugs too, if i can get at them! Std. plugs on 340bhp WRX maybe possibly a bit of a strain.

I have had a suggestion form a "semi" mechanic, just to rule out MAF sensor, that if I unplug it and start car, and will run rough but should be able to keep it going by feathering throttle?? This true, would just be another item for me to tick off. Would have thought a MAF would throw up CEL light though.

Cheers bud, he has just text me and sorting out which evening to pop by. Cant say how much the help and ideas im getting are really appreciated - physically for the car and mentally for me!!

Dont have a fpr fitted, Andy F said didnt need it with the 2.5 (didnt ask exactly why). Going by what you are describing, sounds similar, the car is running on the fuel pressure built up when turning the key to ACC then running off that initial pressure for 20secs then slowly the revs drop and dies (ie . like its being starved of fuel). Quick question, but why would the fuel pump be ok every time I pre start (ie clicks, and builds up pressure prior to starting engine) , then fail after the engine has started. Have pm'd ScoUK / Al to see if he has diagnostic sstuff, after all he mapped his car himself.

Yep, certainly worth look. It will prb be weekend before I get a chance, Il look out the fuel pump/filter and how to I check the relay? All I know so fas is it a found metal thing at passenger footwell (but I havent actually looked it out yet). Cheers for all the effort and replies guys, really appreciated. When it didnt start at all on Sat I was freaking out thinking something huge had went, but now engine starts (even if its only for 20 secs) the engine sounds fine. I had heard that the fuel circuit is seperate from the the engine ecu circuit - possible reason why no CEL light. Cheers again.

Have still got the original pump, only done about 15k, will give it a go, easy to do on the wagon, or should I be looking at fuses, it defo works at startup. Is there anything to check that connects the immobilized to the pump?

Think i need to buy some extensions then and maybe a slim 16mm plug socket (if you get such a thing). The two I have just dont seem to be reaching in, without hitting the engine hole. Im now wondering if by having the coil packs disconnected for a few hours allowed the plugs to dry out a bit, hence why it decided to start, but maybe not dry enough to hold the engine on. Dont think its immobiliser, ive had that before and lucky if i got 2 to 3 seconds of engine running before it cut in, im getting a good 20 secs now before cutting out. Could be my imagination, but the car seems to be running a bit longer (only a few seconds longer each time) each time I start it. Havent given up for tonight, knackered. Il get plugs ordered new plug socket and keep pursuing for somebody with diagnostic to try and rule out sensors (still no CEL light, which is good - I think?) Plus battery is needing time to recover after all the cranking today, its back on charge.

Its std. subarus own plugs that are in, AWD perth didnt have uprated plugs at the time I was down for service / remap. Can spark plugs fail when in demand, ie. engine running on boost?

Ive got 2 16mm spark plug sockets and neither of them grabbed the plugs??

Na, stay well clear from induction kits. Im starting to think sensors too. Do any of these sensors come in after the car has started them unable to keep the car running? Im hoping Al is going to be on later and says he has a code reader, would be handy. No where near a dealer. Prob wouldnt do any harm to try some plugs, just cant seem to get the buggers out.

Ok, the latest is... Took off fuel hose, turned key to ACC, heard fuel pump and pumped fuel ok into jar. So fuel supply is ok. Took off intercooler, checked hoses, all tight, all clean, etc. all fine, quick peek in the turbo and all clean, no oil or anything like that. So put everything back on (a JDM STI i?C is a b**ch" to take on and off), thought I would give it another shot. She started... but...... she will start, take and hold idle herself (with engine sounding fine) but after 20sec or so she starts to cough and splutter then die. When she does idle for that short time engine sounds perectly fine (ie no "out of timing" noises or rattling), and can even rev her a bit too. But no matter what - she starts to cough then die. At least I know timing / timing belt is okay then. My uncle is a mechanic but no expert on Subarus, likes his Audis though. Suggested possible cam / crank sensor, some cars have 1 or 2. Anyone have any details on these sensors, if the Impreza has them. I did think the CEL would come on if this was the case, but im wondering when I had the decat put on the CEL light was put off by Andy F. Would this mean that the CEl wont come on with any problem or was it just switched off with regards to lambda sensors/decat etc.? Another option, could it be spark plugs at 38k miles? What is in mind is that I had spark plugs done with my first TD04 remap and decat and AWD Perth were surprised to see that the 2.5WRX required different plugs than the 2.0ltr. We are talking about 2 year ago now when the 2.5 were quite new. So, AWD didnt have any uprated plugs available for 2.5 at that point and just nipped round to Subaru John Weir Perth and put in std. plugs. Is it possible that these would be failing? Would failing plugs put up a CEL? I can get the coil packs off ok, but what size of socket do you need to remove 2.5's plugs? Ive got a few spark plug sockets from doing missuses focus and rav4 but none of them seem to fit and grab the plugs. Do you need a "special" thin socket? Sorry to yak on a bit but I though I should best it as best as I can. Option 1 - Sensors (but no CEL, bit strange). Option 2 - Failing Plugs Engine stuttered and died at about 3.5K revs on a "good bit" of boost! As always, thoughts and opinions definitely and much appreciated.

Yep, clean the MAF near enough 6 month to keep it "tip top"!

Nope no engine light on, which im hoping is a good sign and its something simple. If it was a fuel cut on full boost, does anything need to be reset after?

Hi All, ________________________________________ Another Update Running sweet now Culprit and pics on latest post ________________________________________ Update, shes decided (next day) to start but still dying after 20 sec, details on posts below. ? Fuel pump, relay?? ? Spark plugs starting to dry out after 24hrs...??? ? No CEL light though. ________________________________________ Somin's up with my car. Was driving it (2006 2.5 WRX, remapped with VF34, 38k miles) yesterday, all warmed up prior to setting off and 3mile away from the house while in fourth it cut out on me and hasnt restarted since. Although wasnt foot to the floor I was at 3000rpm - near enough full boost when I got the fuel cut / stutter feeling, it hung at around 2500rpm for a couple of seconds then died, instead of cutting then coming back. Towed it home with my trusted wee rav. Thought the engine may have flooded with me trying to restart it but this morning still nothing. Can hear fuel pump with acc on, then starter motor, car feels like it wants to get going but nothing, no coughing or spluttering, just wont bite for that start. No engine check / CEL light on. Half tank of Optimax. Started fine earlier on in the day, no smoke or stuttering. Felt fine and smooth for the few miles I got and was out in it the night before too. Anyone any thoughts where to start looking first? Dont suppose anyone has got a fault code reader in Moray area?

Yep. totally agree xbox 360 for current gaming variety and online gaming but I believe the PS3 has more gaming potential. Scooby (apart from new hatch v. Evo X) PC xbox nikon blonde

Already ordered, yep its the Sessantas (with the "funny" tread design), get them fitted this weekend if not sooner. £105 a corner, fitted, balanced etc. Are the replacements going under same name or to be renamed as a new tyre?

If your just replacing the rear one would only go 20mm, you dont want a tail happy bmw. If your replacing the front ARB aswell, go up a bit further with both onto 22mm or even 24mm adjustable at rear.

Similar, afraid ive just to make do with scottish sunlight instead of nice lights to give glossy finish! Autotrader... Mine....

Pics added up top now. Just been out with the 888's and my god, what a tyre, grip was just unreal! Must point out, it was a dry day Can see why its a track tyre though, noisy and picks up all the crap of the road, can see why with the very little grooves there are on them. Fine to have a shot of them and for another couple of weeks but I think Il put on my favorites soon, Vredesteins.

They are, but well worn, wont get long out of them but Il give them a go and decide what tyres to replace them with, originally big Vredestein fan so could be a new set of Ultracs on way soon.

Yep, tbh, bit nervous about trying them in wet!

Picked up a nice set of 2nd hand wheels today, 18" OZ Prodrive alloys, same as the P1's I believe. Just giving them a clean up tonight and a few coats of wax inside and out before trying them on. Hopefully get some pics up of the wheels on the car the morn.

lol! The round ones!

Ah, so thats your one, seen it kicking about Elgin a few times. The photo you took there with the mudflaps and new wheels looks good, damn good, wheel comes out just far enough to make a aggresive low wide stance from behind.
