katconcarne 0 Posted December 30, 2006 Author Report Share Posted December 30, 2006 gdi new crank sensor fitted, same problem still. she's undrivable now, wont rev up. seems to be a fuelling issue as no soot is being put out the exhaust. what are the specific vr parts that affect fuelling?already checked; lambda sensor, fuel pump new, fuel pressure set to factory setting, new filter, tps changed, air flow meter changed. does anyone have any more ideas??thanks guys, Katie Link to post Share on other sites

mk3anni 0 Posted December 31, 2006 Report Share Posted December 31, 2006 pm sentYeah thats REALLY helpfulI have a walbro fitted, i didn't need a remap.If you pull the fuel return line off are you getting fuel through???Just because your not getting soot it doesnt mean there is no fuel. You have to ignite the fuel to get soot, and if you have no spark then you wont get soot......i feel your theory there is floored.Have you checked the plugs to see if there wet......or turned it over with the plugs out to make sure that your actually getting fuel in???Could be a screwed ecu i suppose.

katconcarne 0 Posted December 31, 2006 Author Report Share Posted December 31, 2006 with fuel line off it flows well.fuel pressure gauge is 4 bar with no vac, 3.5 on vac.spark plugs are a normal light tan in colour.no strong smell of fuel.if it starts to die and cuts out you have to turn ignition off to restart or else it takes loads of turns before it starts.the car only has this problem when the inlet manifold pressure drops, but after fitting the pump it has problems in neutral and coming on to powerband it stops revving.thanks guys for your help, Tom, katies other half.

mk3anni 0 Posted January 1, 2007 Report Share Posted January 1, 2007 Dont want to state the obvious.Have you replaced the fuel pump relay????? Link to post Share on other sites
Russ_vr6 12 Posted January 1, 2007 Report Share Posted January 1, 2007 i was gonna say can u hear the pump prime when you turn the ignition on? Link to post Share on other sites
mk3anni 0 Posted January 1, 2007 Report Share Posted January 1, 2007 Cant be that, otherwise fuel wouldn't flow........if your SURE you have a spark and your SURE fuel is getting to the rail which is sounds like it is then it has to be the rail/injectors/injector loom/ecu.I think.

katconcarne 0 Posted January 6, 2007 Author Report Share Posted January 6, 2007 yeah, got a new relay.if fuel line taken off fuel rail and put into jar, fuel not coming through on ignition only on engine crank, whick takes around 6 revolutions to start. is that normal?rail is not leaking or blocked. could it be that its getting fuel and when its rich for accelleration its dampening the spark, ive put ngk platinum plugs in for the obd2 even though its obd1, does this matter?im getting it back on vagcom and to an auto electrician to check out wiring and ecu as soon as the guy is free, which may be a while.cheers steve, your help is massively appreciated, Katie Link to post Share on other sites
