Hot start problem

It was the fuse on the Modwise Hot Start kit - so five minutes later all is fine again now. Thanks

Have you looked into why it blew or just replaced said fuse?

[DastardlyDick]

I just replaced the fuse and I admit I was just happy she fired up again. Went out for a run - got up to normal temps - turned engine off and she restarted fine. But, I know what you mean " why did it happen in the first place?" How do I go about figuring that out?

Mines gone from never having a hot start problem to nothing at all when I turn the key.

Fuel pump primes but nothing from the starter.
Lights don't dim when you try to start it.

Does the immobiliser usually fail suddenly or is it more likely to be the solenoid?

Is there a fuse dedicated to the starter circuit?

[Hoofa]

Oh dear have you tried bashing it in the fitter stylee ? You need a electrician it's good you hear the fuel pump prime though

[WinstonWolf]

This is beyond fitting I just like to figure out what to look for from the comfort of the sofa before I don my overalls

On occasion as thump on the top of the dash just outboard of the Heater controls can help - if it's a sticky immobiliser relay - if it does work you need to get the immobiliser sorted.

OK, update for anyone that's interested.

I made up a bit of a loom with a relay and used the existing switched solenoid feed to trigger the relay and used the main supply to the starter as the power source, switched through the relay.
So far so good, got her up to temp and starts no problem so we will see how it goes.

Thanks for taking the time to reply in such detail, your information is very helpful.

I think option 3 is the best option for me as I have no problem tackling it myself. i was thinking along these lines anyway.

Do you know if there is a wiring diagram or similar that I could use to get the

No wiring diagram available I'm afraid, but its not that tricky.

Top tip.. TVR used all black cables for the security system, I thing it was in an attempt to make things more tricky for a car thief.

Saying that a multimeter makes short work of identifying these black wires, and look out for the heavier gauge black wire when your probing for the starter solenoid circuit, it could save you some time

I made up some simple immobiliser bypass instructions with photos if you think it'll help, just PM me and I'll respond with the info.

Hi just read your thread and have the same problem do still have the instructions as I think they will be very helpful for me too

Wiring wise simply remove the solenoid wire from the starter and use it to to feed the coil of a switching relay- the other side of the coil then goes to ground. The relay switch needs a 12 volt feed on one side - you can spur off the starter 12v feed from the battery , or off the output of the alternator that has a constant feed back to the battery, and then the other side of the switch then goes to the now vacated solenoid connection. You might want to consider a fuse in the 12v feed to the relay as well.

It was pretty much this that I did, and I can report that six months in I have never had a single re-occurence of the problem.

It has been available on griff and chim pages web sites for years how to do this mod. I also send out how to do it, free for 12 years now. Oh tvr land !
