smoke from the fuel rail

[kingfisher]

when my fronty was off the road , i bought a volvo 850 to use till the fronty was repaired ,now i have a buyer for the volvo the problem is when i tried to start it there's smoke coming fron the fuel rail ,it was low on petrol so i put some in but it still wo,t start , it is turning over , and at one stage i thought i was gonna start , but no . any ideas guys

[Sir-Doris]

Sounds like something shorting out somewhere. Possibly a loose injector wire or similar if its in the area of the fuel rail

[kingfisher]

thanks mate will check it out tommorrow

[Sir-Doris]

Any smells to go with the smoke? Different smoke has different smells ya see.

[kingfisher]

well its got a slight petrol smell to it , not a strong smell , and the smoke is a grey colour

[Sir-Doris]

Not plastic or an electrical smell then?

[kingfisher]

no mate , its really got me foxed , i don,t want to spend any cash on it as i advertised it as spares or repair , on fleabay . the guys coming for it tommorrow , but in the ad i didn,t say it was running , still if the guy does'nt want it i will just have to put it down to expereince and readvertise it , i would like to know what it is though just in case the fronty has the same problem

Could it be a cloud of vapourised petrol from a cracked fuel line/fitting ??

[kingfisher]

when i looked earlier there was a plastic pipe that was sitting on the engine just below the injectors i thought it was just a breather pipe , as the one end didn't seem to go anywhere , i wonder if thats it

[Road Hog]

It mat well be the answer to your problem,as if fuel is escaping the engine will be running lean,for starting from cold the engine needs a fuel rich mixture.Got to be worth a look I reckon if only for elimination purposes.

[kingfisher]

yep thats what was doing it , the bloke who bought it is a volvo spares / complete cars specialists , when he came to pick it up ,i showed him the pipe , and apparently it is a common fault with volvos , because the pipe sits on the engine it gets hot and as time goes by the pipe becomes brittle , thanks sir doris and A friend
