try bridging fuel pump relay (bottom right one) - there are four connectors... two smaller ones are for relay coil, so no interest to us... bridge the two bigger ones then fuel pump runs continuously.
try starting then... if it works then you need a "new" relay 167 - think i still got a working one sitting around at home....
if still no luck with starting do you hear the fuel pump (should be audible with engine off)?
should you not hear it check the 12v get to it - if they do and it doesn't run its the pump.
if the pump runs but it does not start check if fuel makes it to the front - undo the petrol hose, put it in a large glass jar and get someone to turn the ignition on. you should see a nice stream of petrol coming out..... it should not take too long to fill a pickled gurkin jar (say round 700ml), say less than to about a minute.
if you have sufficient flow of petrol there and spark and it does not start look at dizzy closer.....
