95 LT1 No spark

I have a 95 Camero ive slowly gotten it back to running condition after trouble with a broken rocker roller. The car ran great for a week then decided to blow a hose from the water pump. replaced the hose and it ran great for two days and would no longer start.. ITS GETTING NO SPARK.... I have replaced the opti the ICM and the coil along with the wires.. i have ran a few test the car IS sending a pulse to the injectors the icm harness is also getting power but its getting 7v on dc and 4 on ac while turning over.. i have ran out of hope any ideas

Getting 7v on what test? If it is supposed to be system voltage (closer to 12v) something is wrong, there.

Re: 95 LT1 No spark

Which ICM terminals did you measure with those results? I assume the 4 volts ac was terminal B (white wire). Was the 7 volts at terminal D (white/black wire) while cranking?
