it's a long read but please gimmie a hand here.

Hi guys,

so since i've owned my VR its always had a starting problem.

It will wind over and over and over and over alot of times before firing up (for about 15secs). then sometimes it will run like a pig & stall on me.
then i'll fire it up again and give it some juice (bring it above 2000rpm). and it'll run fine like a normal cold start. ALSO you can smell unburnt Fuel. strong smell of it on start up..


also after depressureising the fuel system, it will start Perfect. thats why i thought leaky injector.

unplugging injector on rear passenger side will mke it start a bit better. but not much. might just be a imagination thing.


So far i've been told it could be:
Battery
Leaky injectors
ECU
Fuel regulator



i have just finished changing the two injectors i though were leaking (with second hand ones).

i am about to change the ECU with a spare i have.
and i also have a 2nd hand regulator im gonna try in it tomoz.



has anyone evr had this problem?.......does anybody know what could cause this??...

any questions are fine people, please help!


thanks

Hi there, not 100 % sure but maybe vacuum leak? mine does the same thing and when i checked the codes the error code for vacuum leak comes up. I cant find the leak but if i can and it fixes the problem i will let you know. Mine also idles rough/low and very occationally will stall at idle

the coolant sensor tells the ecu how much fuel to spray in so if its getting stuffed it will give it too much.ide pull the vacuam hose for the fuel reg off and make sure no fuel comes out of it and check all the injectors for leaks you can lift them all out connected to the fuel rail and power up the pump to check
