cheers for replys
checked it again tonight and the 1 only pulses (the black and orange wire) the other outer wire (black and green stays neg when cranking no pulsing) i pulled the plug off the crank sensor and the black / orange wire stoped pulsing when cranking) then i took off camshaft sensor plug this did not make any differense to either wire could it be a cam sensor faultly ie not pulsing the other side just staying neg?
