Another silly almost stupid fault I recently experienced with my wife's 924S which had been running fine all week ,she switched it off outside a house to post keys through the door,then would start but kept cutting out turned out to be the fuel pump fuse -the fuse metal strip had developed a microscopic split which stopped the pump running although enough contact to start .

My turbo had those symptoms a while back, turned out to be the distributor cap, I was considering the fuel pump after exhausting what I thought was everything else, no it was the distributor.
BTW you do not have to remove the bell housing to remove the flywheel sensors as I also did this when searching for the fault.

I run the 9XX fuel pump from JMG with 55lb injectors. You can get away with standard with these injectors but it is a good upgrade and good future proofing. There was never any mention of upgrading wiring. It runs on the same size fuse so don't see why a wiring upgrade would be necessary?
O.k. My trusty old 944 S2 was running absolutely fine and dandy it had just been MOT tested and the garage rang to say I could collect it. I duly settled the bill got in the drivers seat switched off the immobiliser turned the key the dash lights all lit up as normal I turned the key further in order to engage the starter motor and ...........nothing[
]. This had never happened before in fact with the new battery and new starter motor I had fitted several months prior to this my car was an excellent starter. It had only just been started moved and parked up without any signs of trouble a few minutes before my arrival. Two months later the car is still at the garage with the same fault. There seems to be no apparent reason why this should be. If anyone has any bright ideas or suggestions as to how we can get it running again I would be very pleased to hear from them.
I already have a gallon of petrol and a match waiting.......... just in case!
Thanks and regards.

Sounds like 100% the immobiliser. All immobilisers must to be certified act on the cranking circuit. I suspect like most garages yours are either scared or don't understand electrics. I would find all the immobiliser wires and remove them and make good. If you are not 100% with electrics then you are better off removing it, or getting another installed by a verified vehicle spark that most importantly you trust.

What model is the 9XX pump ? I said I'd read some people uprate the cable on the Bosch 044, perhaps on other pumps it's not necessary.
A few years ago my household immersion tank was replaced but hadn't yet been wired up, needed some hot water fast so I did a temp connection with an extension lead to a wall socket, the 13a fuse didn't blow but the cable got hot pretty quick.

There was some modification to wiring and vacuum hoses to fit the Augment gear but I didn't do it. Was all left to Tom at Augment.blade7 said:
I splashed out and bought a new fuel pump from Euro Car Parts. Bosch item. £112 inc VAT and shipping. Not fitted it yet but guess what....car is starting and running beautifully again!! May be it just don't like cold early morning like me.

Do the 3 wire jump on the DME relay socket and (carefully) a direct 12v jump to the starter and see if it fires up.
Evening all.
Thanks for the replies. The garage looking after my car is a well established independent specialising in classic cars ( the owner used to work at a Porsche dealership and knows his 944's). I am not technically minded and have difficulty wiring a 13 amp plug! However I do know an excellent local auto - electrician so perhaps its time to give him a call - surely there can't be too much amiss?
It may be a week or two but I will report back with any findings.

Hi m8. We had a look at all kinds of weird and wonderful things with electric wires attached and as you say it was only by going back to the beginning that the faulty distributor cap was found. The strange thing is it had not shown any signs of failing and in the space of a few minutes went from working fine to not working at all. I know its a trek but will you be coming down to Rutland?

Ha ha Zeusy only clicked on to who you are,hope you are well !
Bought an S2 as a easy cosmetic project, still at the body shop for paint, hoping to have it back this week if I get it put back together then I may come down in it, bit of a haul, but I may stop over.
Any suggestions for digs appreciated from the locals.
Told you it was the bloody distributor cap, bill is in the post []
