Failure to start....any thoughts??
Discussion
I had a good 15mile trouble free run today...when I came to re-start it to get back home the engine fired up and then died...any subsequent turning of the key resulted in nothing I have to re-insert the immobiliser transdponder key every time i try to start it..it fires up and dies...eventually pushed it to a downward incline...hurriedly inserted the immobiliser transponder...switched on the ignition and bump started it. It fired up and stayed running normally all the way back home.
Is this a dicky immobiliser...? or is this me fuel pump acting up...will it run without the fuel pump running relying on gravity to feed fuel to the engine...the reason I ask this is because my fuel pump is unusually quiet...
Anybody's thoughts appreciated....Paul

It could be the immobiliser, depends how it's wired in. If it immobilises the fuel pump then I would say that's a stick-on.
It could also be a fault with the fuel pump itself - if you can't hear it as normal then it's maybe stuck. If it is then the fuel is unlikely to go through by gravity - these engines need a decent fuel pressure through the injectors, unlike a carb-fed system where the engine vaccuum draws the fuel into the inlet manifold. Even then though, unless the tank is higher than the carb, it will need a pump to refill the float chamber.
Could also be a load of other things though!

could be the fuel filter full of crap I, I had a similar problem cos the tank was full of rust the filter gets cloged, have a look in the tank with a torch, if it looks mucky take the filter of and reverse flush it to se if its gummed up, if so , tank out and clean and new filter, been there done it.

Check the connector to the fuel pump. It is about 6 inches from the pump and gets a lot of spray from the road. Mine was playing up (kept cutting out and eventually restarting) and since I replaced the connectors the car has been great fun - for the first time since I've owned it.
Edit to say if the voltage to teh pump is reduced then it could well be quiet. My pump took on a much higher (ie. faster) tone once the connector was replaced.

Thank you chaps...I will check out all these things. I don't know how the immobiliser is wired in...my suspicions are leaning towards that as the culprit. The fuel tank is the original so it may very well have some crud in it...the filters were cleaned and checked on its service but i guess they could still be choked.
I've had it up for sale for the last month or more having decided to move onto a Griff...but the drive out today, despite this little hiccup had me having second thoughts...It's a great car...hmm keep it or sell it...decisions decisioms...

Hi Paul, before you decide make sure you've driven a Griffith, I went to buy one, drove it and wasn't impressed, maybe it was a bad un but I would definately try driving one before letting the S go, I thought the Griffith was less than it had me beleiving it was, however I still love the shape and the sound of the Griff but the S has all the things I like in a sports car and I find it relatively inexpensive to run. On the other hand I'm sure others have tried a Griff ,bought one and love it. Paul.
Yes you are right...I need to drive a Griff before I take such a drastic step.
There's a dealer near me who will take my S in part exchange for a Griff...too many S's up for sale at the moment I think.
The weather doesn't help either. I asked on the Griff forum if anyone regretted upgrading from an S and the concensus was pretty much for the Griff. Mind you..they would say that I suppose.
