As above I have googled it searched on hear but still no idea. I'm thinking its the one with 17 on but prob wrong. Any way the issue I'm having is the car fires starts then dies instantly it done this 4-5 times then wouldn't start at all it turns but won't start now so I'm thinking it started a cuple times with the fuelthats there but now thats burnt of it wont fire up? just my thinking? fuel pump relay possibly ? Car is a mk2 gti 8v k jet 1986 Can any one help please???
Ok fuel pump does not make any sound when ignition is on. Now am I right in thinking they don't make a noise (priming) So if I bridge the pump relay at the fuse box (wire across the 2 large slots) assuming it is the relay will this enable the car to start? Is there any way to test the the fuel accumulator? Cheers mark
yes slot 2 for relay, easier way to bypass imo is swap the 17/18 relay into the pump socket this will make fuel pump come on with ignition. to test accumulator and other parts of fuel system you need a set of pressure test gauges unfortunatly. if you can remove the wee screw in the back and fuel comes out that means its dead though
Ah ok I will try the wee screw. So far iv got spark on all 4 plugs in a consitant patern Iv put a live feed on both pumps in/out tank and both come on Iv put a new relay in with no diferance there is power going to the relay. Now I sprayed easy start on/in the filter and it fires but dies instantly so I'm thinking its metering head/ fuel delivery , the pin in the metering head is free and the flap lifts with a little tension so I'm a bit stumped now. I think this is getting beyond my tinkering nohow. So prob going to give it to dtm (Bosch) specialist as I think I would rather the specialists deal with the fuel than me.
have you swapped the filter yet? always worth a go for these kind of symptoms also if you pull the feed line off the metering head and point in a bucket do you get any fuel out when the pumps prime/run? if not the non-return valve may have packed in had the same on my mk1 cabrio
Thanks for your help mate iv learnt so much about k jet in the last few days but it tint out to be a broken wire from the in tank pump to the outer pump it was taped up so looks like an old shoddy repare so new replacement loom now fited and its alive woo hoo
Ah just hade the dam thing not start again so I swaped relay for a new one I lukily didn't retrench and now it works fine but the revs seem to be limited to 4.5k ? Does the relay control the rev limiter?
Just done a search on hear and found a very good thread on this. Titled - http://www.clubgti.com/showthread.php?188590-Rev-limiter-on-an-8v-Scirocco-(Kjet) So I now need another relay I'm going to get a second hand number 62 so it's back to normal
