get tour mates to push it down a hill and see it will turn over.i cleaned the battery terminals and battery leads with petrol and a wire brush. even took the leads apart and cleaned them good. it has solved my rough idling for now. i changed everything else befire that but silly me didn't think about battery. checked with a multimeter-ok. instead should've cleaned the terminals and the leads and got rid of the grime. sometimes simple things are overlooked that can make a difference. other people missed it as well.

if it cranks fine and does not fire then pushing it down a hill won't make it fire either.
have you tested the coil? (take off king lead from dizzy and place next to engine, then manually power the coil up / down and see if it sparks....)

N reg.... could be ADY or AGG, which one is it?

Can you hear the fuel pump prime, does the fuel relay click too? No 167?

Check if the wires running to the crank sensor are all split and broken.

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.....

Haven't see anyone suggest it yet, Have you checked all the fuses? A blown engine management fuse made my abf refuse to start a month ago!

Appreciate all the help guys by the way  :smiley:

I took relay 167 and ran a 12v through it and I can hear it clicking.  When I turn ignition on i dont think k I can hear the pump priming, ill try again when I get home. All fuses are fine as well. Checking the fuel flow with the jar is the next job I reckon
