running problems

[silk violet]

hi there i have a mk 2 gsi 20xe and it has been stood for about 3years and i have replace pretty much most parts on the car and finally started it the other day and finally let it tick over to warm up and it revs up on spot fine but as soon as you you pull away it dies down and struggles to pull away but as soon as i dip the clutch and rev it its great and revs straight away but i try and pull away again and it wont accelerate hard....???

Sounds like poor fuel pressure

The part(s) of the fuel system at fault lol

[silk violet]

i found today that the fuel regulator has a small patch of what looks like liquid metal on the side of it would this make any difference....???

[millworm]

Might be worth replacing

[silk violet]

i only have a 3.0bar type as a spare fuel pressure regulator and not a 2.5bar which is what is on the car at the mo will this be ok to use as a replacement to see if this is the problem....???

[millworm]

It should be fine mate just to test

[chrisd1986]

Could be also check for any leaks, kinked or dameged lines or you could have a worn pump or the problem I had a tank that was rotted inside which blocked the pickup causing the same issue

[silk violet]

its had a brand new fuel tank and rubber pipes that come off it and complete 8mm copper fuel lines from front of car to rear....??

Ok just ruling out possibilities, was it a gen or spurious tank? And I would try the fpr by th sounds of it there has be a bodge which has just failed

[silk violet]

[silk violet]

HI YA PEEPS.... i,m still having same issue i,ve replaced fuel tank, rubber pipes, copper lines, mass airflow sensor, tried a diff set of injectors, new spark plugs, i,ve also replaced the fuel relay fuse but i have wired the fuel pump on a switch perm to battery as when i connect it to the main wiring loom fuel pump does'nt work also i do think it could be fuel pump not pushing out enough pressure ...?? i do have another engine wiring loom as a spare if i want to replace but just trying to rule out others first...? any suggestions would be really appreciated

Take the throttle body off and clean all it's passage ways, check all the earths are clean and secure (fuel rail earths and gearbox earth), fuel filter clogged?

[novacarl92]

having the same prob with the same engine have you sorted yours out silk?

[silk violet]

Novacarl92 no I think I might have found out what it is but gotta try the weekend I have 2 seperate fuel relay fuses and gonna try the second 1..?

[Novasport]

Did it have a new tank recently or before you put it away 3 years ago? Has it got fresh fuel in it? Have you replaced the filter?

[silk violet]

Yeah I put the new tank on recently and yeah its had fresh fuel and a new filter... plus it's over fueling really bad brand new plugs are black..?

[novacarl92]

Novacarl92 no I think I might have found out what it is but gotta try the weekend I have 2 seperate fuel relay fuses and gonna try the second 1..?

[silk violet]

Alright novacarl92 I found out what the problem was with my car... it was the fuel relay on mine there is 2 so I replaced both of them....?? Or you may have. Cut in the engine loom for fuel relay....
