hi all
i hope theres some one out that can help me......

car was fine on wednesday evening but thursday morning would not start....
ive been looking at it for the last few days but now runnng out of ideas.
i changed the ht leads then the cap and rota arm but still no spark i checked the book and did the test on the icm and there 12v and to the coil. the book also said to check the coil from the 4 pin conector but no 4 pin conector or coil..... its all in the distribitor. does any one know how to check this type of coil ? the main relay seems to working ok and clicking in the right time.i also checked for error codes but no errors showing up. now im stuck on what to do next

any help would be great miss driving my car
