« on: 12 April 2012, 14:34 »
looking for some advice having major problems with my cabby that i have put a vr lump into.i had it all up and running fine last week,now it's dead will not even crank over.
cant even hear the fuel pump prime,all i get is the dash lights go to crank and nothing.

anything i could have missed,connections wise.

i have power to lights,windows etc just nothing engine wise

the starter could be jammed. Have you tried bump starting it? Check your relays aswel. If you say the fuel pump dont prime then it might be the fuel pump relay.

I would start by checking all wiring incase something is loose. You never know.

ignition switch maybe? i know mine is about ready to give up, plays up intermittently with similar symptoms but a little wiggle of the key and it'll fire up.

could be lots of things..... but is this a post 1995 motor (as they need the key and transponder to match the ecu..or a bypass fitted)
