put me down for one set please Dan.p

FIXED IT :-) Many thanks for all your pointers and tips. Was a combo of small faults just to make things difficult, Replaced non return valve on the front of the fuel pump which improved the cold starting pressure, tested the injectors in some bottles and all spray a good cone shaped pattern (A scarily large amount of fuel with the metering flap lifted all the way up, ah well its only petrol not as if its that expensive LOL) cold start injector/thermo time switch OK. The final thing was the air valve below the induction pipe between the metering head and throttle body had worked its way out and was resting against the hose giving an intermittent seal but fell off while i was messing, once re fitted it has started first go every morning. Once again Thanks everyone. Dan will take you up on the bits if only to look after them in case of emergency, Cheers mate.

This happend to me a couple of months ago, could not find a leak to speak of untill on the way to work one morning, the hose feeding the oil cooler gave up, was split on the inside wall of the pipe and leaking past the clip when hot. the outside wall of the pipe finally went revealing the fault. might be worth look and a pressure test.

update, Thanks aide, the diaphram in the original WUR is leaking so replacing with an old MK1 Goof one i had and blanking the vac pipe gets around this for now, i have unplugged the cold start injector and it did improve but i think that this is because less fuel is going in on the first crank, Fitted my fuel pressure guage jig between the metering head and warm up reg on sunday and discoverd the system wasnt pressurized when undoing the pipework but once primed the pressure stayed up??? Cant leave pressure guage on the car as bonnet wont close(90 bend required), accum and fuel pump check valve are good so i think the injectors are leaking :-( can anybody point me to Davidwort's write up on this.

hI all, anybody had this problem with a 1.8 16v motor? Over the xmas break my car devloped a cold starting prob It seems to fill the bores with loads of fuel when trying to start from cold, removing the plugs reveals they are completly washed with fuel and cranking over the engine with the plugs removed blasts lots of petrol from the plug ports. I suspected the warm up reg and replaced it with another which slightly improved the cold staring but it is still very hit and miss. It is possible that the replacment warm up reg is also faulty as it was kicking around my wokshop and is of unknown condition. Any help would be cool Thanks, Dan.p
