Hi all,

Went to start the Griff today as the weather seemed nice, I hadn't taken it out for a bit, battery was all fully charged,

Placed the immobiliser key as normal, feel pump primed as usual, tried the ignition key, nothing happens at all, not even a click. I did have a read on here that it could be the alarm, and banged the dashboard to see if it would work, but still nothing,

It worked last time I drove it as well! the electric seem to have a mind of their own..

What els do people think this could be?

I've swapped the two silver relays round to see if it makes a difference, and purchased some new ones just incase its those.

Its also just had a new starter motor.

James.

Many thanks, ill see if I can have a look tomorrow, I'm not the most electrically minded though..

I believe the main ground connector is on the NS outriggers support (mine is LHD, hence my cautiousness) the big amp fuse is on the lower NS longitudinal, the connectors of the startermotor are just there......

You would ideally use a ramp for this....

Should do hopefully, it had a very similar problem when at the Le Mans classic, bump starting worked fine there .

worth reading this thread: http://www.pistonheads.com/gassing/topic.asp?h=0&a...

To rule out the ground, run a jump lead form the -ve terminal of the batter to somewhere on the engine, the point about the fuse should not matter as the +ve feed to the starter is without a fuze (on mine anyway!), the problem with the fuse would look like charging issues. The starter motor can be ruled out by putting a meter to the smaller wire that goes to it that activate the solenoid, it's a lot easier to look up the hot start wiring install instructions to test it in the footwell rather than under the car smile

Be interesting to see if this goes anywhere James as occasionally I get exactly the same issue with my Chim. May be wrong but I wouldn't imagine it's starter connections as the dash lights don't even dim upon turning the key, I can't hear the solenoid click either. It seems different to the 'hot start' issue so commonly spoken about in TVR circles

Will do smile That sounds very similar this problem, as I turn the key theres no dash light dimming either.

Just trued to call the local garage, and they recommended calling an auto electrician.

Just had a new starter motor.... I'd guess the wiring hasn't been tightened up or a crap quality new starter that's already been cooked..

Could well be... Does seem to be displaying the exact same problem that it did when it broke down abroad, and resulted in a new motor.
That seemed to happen at the most inappropriate times, and work when I didn't need it..

Just borrowed someone to do a push start, immobiliser in, ignition on, started first time with a push start, let it warm up, turned to off, tried it with the key, Started first time!!


Very odd!

All the evidence suggests your immobiliser is the component letting you down.

If you really want to make these cars start reliably hot or cold just follow these 4 steps.

Step 1: Bypass the immobiliser on the starter solenoid circuit (or replace the immobiliser)

Step 2: Improve the tired old feeble hugely long battery to starter cable with something better

Step 3: Add an additional earth from the battery neg terminal to the engine block

Step 4: Add a suitable relay to the starter solenoid circuit where TVR neglected to fit one

As long as your battery & starter motor are in good shape you can say goodbye your failure to start issues for good yes

If you need instructions on bypassing your immobiliser send me a PM.

Hi all,

Just an update, Just to see what would happen, Ive replaced the two silver relays in the footwell with new ones,

Strangely it seems completely fine now... Seems to start every time, I even risked taking it to Blackpool and back to see the illuminations, and behaved brilliantly there too smile

May well fail again, but would be great if it was just the relays

James.
