I have a very odd fault. My Classic is a 1992 I have owned her for 4 years and never had an issue. A few weeks back the gearbox seemed to be a little hesitant. I took her for a run and the gearbox seemed to settle. I pulled the autobox dipstick to check the oil and the car died instantly . She will not fire, the fuel pump is not working the injectors are dead, but here is the rub, the previous owner fitted an LPG kit. I have checked all the relays and and fuses for both the car and the LPG system and cannot find anything . Is there some thing I am missing with the gear box ??
