The joy of TVR

[vee5]

Following a few laps at the Ring I returned to the paddock allowing it to cool off and the car was ticking over normally before I switched it off. 15 minutes later I retuned to the car and it wouldn't start - fuel pump wasn't running. To cut a long story short I checked the tilt switch, wiring harness to rear of car, fuses, swapped the relays and even tried bridged the relay contact "manually". Still no power to fuel pump. Car was then recovered to local (non TVR) garage for the night. Next morning at the garage a bypass power supply to the fuel pump got the pump running but there was no signal to the fuel injectors so the car wouldn't start. Battery had plenty of charge in it. Lengthy phone call to a very helpful and patient Racing Green allowed a few other things to be checked but ultimately the car would not start and it was recovered back to Racing Green, taking about 2 weeks (from Germany). RG receive car and find the battery has deep discharged in transit so fit replacement....... and the car starts on the button!

Sorry about the long posting, thanks for staying with it! Thought I'd post this on the off chance that someone had been through exactly the same scenario, as there are about a hundred different possible causes and many of them could be sporadic.

My guess is that it was an alarm/immobiliser problem and it has now been reset by the battery voltage falling so low.

Yep I would go with immobiliser as well, except, presumably the immobiliser works on the starter solenoid supply as well as the fuel pump ( normally does) and it sounds as if the car was turning over. Having said that I have had two of the original factory fit boxes go intermittent on just one channel.
