right i've got a spark now, very bright blue at the king lead, and bright orange at the plug leads, my fuel pump is working, ive disconected the coolant sensor and the pump runs for longer, ive slackened fuel pipe and theres high pressure there, why won't it start????????
help before i pull the last of hair out!!

 

it might be that fuel is not reaching the cylinders your injectors may not be pulsing so you might have fuel at the rail but the injetors arnt being pulsed but it can also be that the injetors are fucked but would most likly be the driver of the injector so would bet its the ecu .. see if the spark plugs are wet of fuel expalena littel more as to ow it broke down and

 

found it, checked every system, all ok, went to check the dizzy cap and it came off in two pieces, looks like it had been cracked for a long time!

 

god knows how you had a good spark then, don't make sense
good job anywho..
