Help looks like owning a tvr means joining AA / RAC.

1999 4ltr chimaera. Afer travelling about 10 miles and cruising at 70 engine died!!!!! Pulled over and checked a few things out. Ignition electrics appear to be working ok as engine is trying to fire but will not run or tick over. Can not hear the fuel pump priming. Wires appear to be still coupled to pump ok but not been under yet to have a good look. Any ideas on checking through the pump electrics if i find there is no voltage to the pump? ie which is the fuse, how do i get to the fuel cut out switch. If there is power to the pump will the pump continously deliver fuel if i uncouple the pipe to the fuel rail, can i check the pressure by coupling a gauge to the end of the pipe and what pessure should i get.Could it be the fuel pressue reguator? Can I clamp the return hose from the regulator to prove this? Any other thoughts? Many thanks to Bob for towing me home.

Many things it could be but if you can't hear the fuel pump priming then suggest the first thing to check is the immobiliser as it will inhibit the pump.

See if you are getting a 12 volt supply to the pump. Not easy as its located underneath the rear nearside above the driveshaft.

ETA: just re-read your post and if its turning over but not firing and you can't hear the pump prime then most likely the pump.

Turn it over on the key with a plug out and see if petrol is being delivered to the cylinders.

Check fuel fuse and relay

I changed all my fuses to these

In case of just such a roadside event.

If you owned any 12-year old car would you not join the AA/RAC? Come to think of it, just any car?

That was my first thought

Call me stubborn or lucky [not what my better half called me!!!!] but I've gone for 30+years of motoring without belonging to a breakdown service,[always had a few tools/spares/mates to hand]. Anyway I've now joined the AA. That was easy! Just got to fix the chim but that will be next weekend, probably not as easy!!!!!!! Thanks to all for the advice

Had this exact problem on mine, turned out to be the fuel relay. Think they are an ~£8 Bosch part commonly found in 90s BMWs. Unfortunately I've not got the part number to hand. The fuel relay is 1 of the 2 identical looking silver relays in the loom in the passenger footwell.

If you have a multimeter to hand check there is voltage across the correct pins on the relay when ignition is primed.

Happened to me in Spain last year (on the way to Le Mans) In my RV8 powered G33 which has the same loom and engine electrics as a Chim. The fault was a chafed through wire to the fuel pump relay.

Always carry spare silver (ignition and fuel pump) relays. They are diode protected so its not a good idea to substitute with a regular relay.

Chim back on the road Turned out to be a fuel pump relay which after reading the advice given and looking up threads was the fist thing i tried (Lucky hey). Thanks all for the replies and all piston headers who post their problems and remedies that make owning a TVR a lot easier
