I'm guessing the fuel pump has stalled!!! Drawing to much current trying to start and blowing fuzes.

Don't be cponned into a new fuel pump assembly you can change the pump as Amar can attest to.

Default problem resolved

Got my a8 back today....just as you had said....the fuel pump had failed....fortunately the chap I gave the car to was really reasonable and changed it for next to nothing far as I am concerned....think he just charged me for a fuel pump.....

Curious though...why would a bad fuel pump draw so much current....I would have thought it would just stop working.....

If the pump is stalled, ie some grit or crap stopping it turning then due to electrical mysteries it pulls more and more current to try to get it moving and therefore blows the fuse.

It's there as a safety device and it worked.

No fuse then the pump would melt out and your car would go on fire and.....

thanks for that....sounds like bypassing the fuse and having a dodgy fuel pump is a sure way to a car bomb....thanks god for that thin piece of fuse wire.....
