have u a knock sensor fitted?If so make sure you have not connected the crank/knock sensor the wrong way round!or it might be the phase sensor you can get wrong with the knock sensor

SWIFTY

dont think i have, the only other sensor plug that is anywhere near is my dizzy cap one, but that is black so i no its not that one

cool well the crank sensor needs to be around .8mm from the lugs

SWIFTY

ill go have a look but im sure it right.
is there a way of testing it with a multi meter

SWIFTY

the gap is right


i put a plug in the lead to watch if there is any spark.

when i turn the ignition on and of there is a spark
but no spark when you turn it over

Is your fuel pump working when you turn the engine over?

SWIFTY

when i put the ignition on i can here it kick in.


but i noteiced somthing if my dizzy cap isnt pluged in it dont kick in till i plug it back in, is that normal.


also spoke to a mate and he told me it shouldnt be sparkin when i turn my ignition on and off.

The fact that you can here your pump kick in tells you the cps is ok.
As for unplugging the dizzy I would have thought that normal.

maybe stupid question, but have you checked the timing is right? dont know if its wrong it just sparks at a wrong point or it doesnt fire at all...

SWIFTY

yes mate checked it a few times

i was told if it wass rong it still sparks but not at the right time.



i have checked it from the coil wire aswell and its the same there as the plugs

tabetha

The ignition timing is fixed mechanically by the CPS alignment with the crank pulley, so if valve timing is correct so is igntion timing, though it is possible to get cross firing in the dizzy cap, but it's not this otherwise you'd have a spark.
