Advice please

Took my 3.3 turbo out last night (first time this year) and it was ticking over nicely in the garage, but when out driving the engine was cutting out every time I needed to stop at a junction. when I did restart the engine there was quite a loud electrical humming sound coming from the off-side engine compartment.
A couple of times there was some juddering when I was driving as well.

Could this be electrical/fuel problem

any advice would be welcome

Check fuel pump first.

Worth checking your DME relay also. Remember this little devil performs two functions - powering the DME & injectors and also the fuel pump.

I carry one in the glove box, if it fails (which they do) then you are stuffed!

I don't think any 930s have dme - I know it's a major factor on 32 but not on a turbo motor

I would also check for a loose or split hose. The one that runs from the turbo to the intercooler. There is one smaller hose around the side from memory.

Thanks for all the tips, I will keep you posted when I get a chance to look at it this weekend
