cheers jerry i'l check the boost solenoid and i know its a serious problem i have so im not using the car (dont usually get used anyway)
i did not know its why my last engine let go, it was just a guess although been confimed now , the drive home from norwich was very gentle after finding out
think what i need to do is give it to someone who knows what there doing who has a rolling road and give it back to me all tickety boo
v3 STI
boost solenoid and pipes all cleaned with carb cleaner and was oil in them so this may have solved the overboost (maybe) i have not tested it ,
next job of the day was to fit the walbro fuel pump, first thing i checked was the feed to the pump with a multimeter and this shows 4.36 volts, why am i not getting 12ish volts to it , i had my mrs turning the ignition on and off while i tested it as it shuts its self off after a short while so as not to flood the engine (cheers alyn for that info)
i have not yet fitted the pump or opened up the fuel tank ,i just feel stumped that im only getting this little power to it :x
anyone any ideas or where im going wrong
please

Small one's are more juicy
update:
fitted the new walbro pump and got 11.6v so im sure thats alright.
took the car out to see what its boosting like after cleaning boost solenoid and its still going straight up to 1.25 bar then settling straight away at 1 bar as it should be, its an improvement on the 1.4 bar it was hitting before going back to 1bar but still obviously not right ,so im now stumped and going to have to seek pro help and spend more bloody cash :x
could the lambda sensor be making it do this ?

Trev, my '95 would boost to 1.1 on standard ECU with its Magnex decat. Then I fitted panel filter and that was enough to let it boost further and hit fuel cut (earlier car has v.low fuel cut, something like 1.2bar). Reckon you just need remap. Cheap fix would be manual boost controller like Dawes device, but it sounds like from your other problems that it needs remap.
