Air in the fuel pump......

[Razorhoof]

I have done the 'pumping the primer' trick and it was fine for a day and then yesterday it started oplaying up again (low idle at lights and the engine cutting out....). When this happens I get quite a lot of black smoke that turns white and then gradually disappears altogether from exhaust as I increase revs by putting my foot on accelerator pedal to drive away. Either that or the engine cuts out before I get chance to put my foot on the pedal.

What could this be? WOuld air in the fuel pump cause this smoke?

Why does the smoke get lighter if I increase the revs again?

I have had something very similar...

initially is was a cracked primer pump... replaced that with a used one from Jotto... that went at the weekend... and just replaced it with a new one from roughtrax... (£62)... touch wood, truck actually started today, and no spluttering...

If its suddenly gone, tehn something somewhere has broken... if its faded out... then it must be a seal...

[Razorhoof]

Yeah, I will just see how it goes.

This only happened after I got a stop switch seal replaced on my pump, annoying really. Should the mechanic take responsibility for this or should I be paying again for another repair?

If I were you, I'd take it back the garage, say it's cutting out, say that you've been told it's probably air in the fuel system and see what they say.

I don't think you need to start worrying about who takes reponsibility or anything. Most garages will just have a look and sort it out.

[Razorhoof]

Ok, cool. I shall then.

[Razorhoof]

Still got this problem. Doesn't happen very often but the longer I drive the worse it gets when I stop.

WHat causes it? How does the air get in?

[The Hornet]

Did you do what Sancho said? What did they say?

[Razorhoof]

Nope, not taken it in yet - a bit skint til end of month mate.....

[The Hornet]

If they did the previous works tell them it's cream crackered since then. Tell them it's their fault, at least they'll look and give you an idea.

[Razorhoof]

I shall, I aint been back in yet though.....

May get it sorted early next week.
