leaky injectors?????

hi guys,, just wondering if you could help me out a little,, i have a mk1 golf 1600GTI hardtop which doent like starting in the cold or hot but does eventually,, plugs leads and dizzy n rotor arm all have been replaced,   the fuel injectors have been replaced aswell,, but i'v just removed the injectors and cleaned the ends up with a cloth,,  turned the ignition n petrol squirted out of 2 of them,, 2 didnt squirt,, with the ignition on  petrol then started to weap out of 3 of them 1 remained totally dry until cranked..

are my injectors working properly?

also the guy who had it before me has wired the fuel pump in to ignition live ie; bypassed the relay which doesnt exist on the fuse boy i have so the pump is always on when key is turned,, is this a major issue? will pressure be to much etc,,

it always fires from cold n then dies,, and takes forever when its warm,,

regards adrian :dontknow:

They should all spray vigorously when they reach pop off pressure.
Sounds like either the injectors are sticky/clogged or theres some other obstruction in the lines to them.

Fuel pump being wired continuous is a bit on the naughty side as itll continue to run even if you went shiney side down into a tree….thatd be kinda bad as itll feed a fire should you be that unlucky.
Get that sorted out asap, it could be a life saver for you.

what do you mean vigorously,, the injectors are new fron GSf, only 1 stays dry the rest leak fuel when ignition is on,,

iv had it a year n jus gettin round to sorting all the probs out but the k jet system is a pain in the arse,, the guy tht had it befor me was a total cowboy; fuel pump wired wrong,, bare wires all over n sump plug ptf tape n silconed in,, roughneck, lol,

Have a read of this:

Injector Test

Note: I have also had duff 'new' injectors in the past….

thanks i have done the test a few ago and the spray pattern is bang on,, conical as it should be,, just not sure on this leaking thing, i wonder if my fuel pump been on ignition live has anything to do with it,, or are my injectors kaput even though they are 4months old???

just saw your blog and was wondering if you could tell me how you removed your injectors. iv tried taken them out as iv the same sort of starting problem as you . i cant seem to get em out and seem to be a nut on a nut and will just turn and turn...what am i doing wrong.. man they are fantastic cars and i love mine to bits but man they can be a pain in the bum.. good luck with yours..take care

You need to get a pair of long nose pliers around the neck of the injector, put a rag on the rocker cover and lever them out. They are just a push fit. Try spraying some wd40 onto them where they enter the head and leave overnight.
