right any advice please, i've got fuel at the rail but not through the injectors, theres no fuel at the return hose either, i think it would be unlikely that all 4 injectors would pack up at the same time, so would this mean a faulty regulator?????????????

could be your pump is turning but there no pressure ive had this before
its the last thing you check as you can hear the dam thing buzzing
away take the fuel pipe off and put your finger over the end while some
one swicths the ignition on and see if it will push past your finger it should
do then you will no weather its that just put it in a bucket just so it dont fire it all over you

fuel pumps ok, i took the supply hose off and put a container in front and put the ignition on and it shot out really fast

make sure each injector has a 12v supply with the ignition on,disconnect the injector plug and probe one of the pins in the plug for 12v,if nothing then check for a bad connection at the square connector block on the bulkhead,the heavy red wire into the block is the injector supply,
although unusual for 4 injectors not to opperate,its possible that the ecu is not telling them to open ie giving them an earth in sequence,this as far as i,m aware is controled by the phase sensor in the dizzy,so a good check the phase sensor gap and of all the connections and plugs in this area is recomended,
incidently how do you know the injectors are not opening?are the spark plugs dry,is there no smell of raw fuel from the exhaust,are u sure its not spark related

did you hold your finger over it as it can shot out but have no pressure behind it
