Just bought the Griff from last months C+S! Help!

[griffrhysjones]

Can anyone help, I was lucky enough (in my opinion) to purchase the Griff which was featured in last months Classic and Sports Car, however problems already! Turning over lovely, nice spark but no fuel pump, after searching on PH decided to replace the relays and check fuses but still nothing. I am suspecting an immobiliser fault, is there any way of disconnecting this to prove this theory? Cheers, Simon.

If there is, then I doubt anyone is going to post the details on this PUBLIC forum. I would suggest that you contact the person who sold you the car for advice.

cheers ( oh..and welcome )

Certainly sounds like the immobiliser. Does yours have the Meta alarm? On mine you only get 10 seconds between opening the car (blipping the blipper) and switching on the ignition, else it immobilises the ignition, on an earlier system it may just kill the fuel pump. I would read the instructions for the alarm and go through the unlocking/starting procedure carefully. If all else fails you can re-set the Meta Alarm by disconnecting the battery for a few seconds, this re-boots the alarm unit. Good luck Rich...

On mine (95 500) when the immobiliser comes back on having unlocked the car, the red led indicator lights up on the centre console dash.

However, I have occasionally had issues when the fuel pumps haven't primed on turning the key. I always wait for the pumps to stop before starting the car, so I always listen to them.

If the car re-immobilises, you can press the unlock buttoin for about half a second and it should reimmobilse, and the light will go out on the dash.

If not, lock and unlcok the car again.

Immobiliser problems are relatively rare I believe.

I would first check to see if you're getting voltage at the fuel pump. Use a multimeter (Maplin) or a bulb of some description.

If the pump is not getting any voltage, then test the voltage at the relay.

Also, www.tvrbooks.co.uk for the Griffith and Chimaera manual.

Congratulations!

Did you buy it from the dealer (Adrian Blyth?), or the guy advertising it privately? I was confused as to why it apparently changed hands (or at least vendors) so quickly.

As well as the fuse in the fuse box there's one in the loom above the battery (well there are two - one for the ECU as well). Check that as well as the one in the fuse box. Otherwise immobiliser sounds most likely.

Welcome to the (pre-cat) club!

Many thanks for all the suggestions and prompt replies! I will be locking myself in the garage this evening and will not come out until its sorted! In answer to Grifters question the guy who bought it from Adrian Blyth didn't like the car so he px'ed it for a Triumph TR5, in fairness the bloke I bought the car from was very nice and has refunded me £1000 to sort the problem! Its just very frustrating that a "minor" problem is putting a black mark on my first few days of TVR ownership. Simon.

Agree it is annoying, but in fairness the car is 'classic status'. Over the years I've owned and leased a fair few new cars, not one of which did'nt give me grief in the first few weeks of ownership.

Worst offender were the new fords, I'm talking mid late 80's, bloody awful things for teething prob's.

Hope that makes you feel a little better.

hi just another thing to try the is a fuel cut out for when the car is involved in a accident if you open the glove box and reach behind you should find a button if its up push it down and try ,sometimes they just go off.
