conked out for the 1st time
Discussion
I have had my TVR for nearly 4 years now, and today is the first time its conked out on me.
It just stalled on me as I was trundling from the office to the petrol station. been driving about 5 mins, 30 mph, slowed down for a roundabout and engine stuttered and stopped. it managed to roll off the roundabout so I wasnt causing too much of an obstruction. Just outside a Porsche centre as it happened
Tried to restart but no fuel pump. cycled the alarm / immobiliser off and on - still no fuel pump . I was debating what to do next - maybe asking the guys in the porsche shop if they could push me off the road at least - but having waited 30 secs and it started normally.
dodgy earth? or summat else?

Whatever you do do not change random items in the hope that it is the problem, otherwise you can go around in circles chasing your tail.
Proceed logically, as said above the pump terminals are a known cause as they are subject to the elements.
The pump wiring passes through connectors by the passenger B door post again prone to corrosion as they can get damp.
It then arrives at the mess in the passenger footwell with the relays and ECU.
This may help:

Dont forget that apart from the initial pulse to prime the pump 12 volts will only be permanently present on the pump when the engine is running so you may need a helper ( or long test leads) to confirm volts are getting to the pump during the initial prime.

so, replaced the pump relay and ecu relay - the pump one was looking a bit cruddy. had a general prod around at connections - nothing lept out at me. the car has been fine for a month, but this morning it did almost the same thing again - died whilst slowing down for a roundabout.
no other issues, in fact the car is generally running well.

I’ve got a similar intermittent problem - same symptoms, and sometimes after it’s been cruising at low speed and revs.
I haven’t played with the relays, have cleaned the stepper (though it was cleaned only a year/2.5k miles ago) and I know the fuel pump is new.
There are other possibilities to do with the speed signal coming back into the ECU not being consistently accurate and the system not giving a dash of fuel to keep it idling.
I’m aiming to get a Rovergauge wire to get a look at what’s going on and get some help from someone who has offered, but this is likely to be in September.
I will certainly report back on here for others to see.
I’m also hoping it’s not expensive!
There are numerous threads on here on this topic, well worth digging.
For the moment though, I very occasionally need to turn the ignition - and my car favours roundabouts for this!
