Hi my mates got a TJ and sometimes when he starts it, it turns off straight away :confused:
Not all the time, just whenever it wants.
Anyone know what would cause this?

Told him to sell it and by a VRX ;)

It's a common problem, as mentioned in the above it could be a connection problem or a low battery

try doing what i wrote in the last link. see if that happens

Thanks heaps mate.
I reckon it must be the immobiliser then, as he put a brand new battery in not too long ago.
