Can you pls explain how you get spark on pos and neg of coil pack. I think you are trying to say that you got a pulse on your test light?? If you do the test at night time its easier to see the test light pulse, this means that the ignition module is pulsing, if there is no spark to the spark plugs then the coil is bad. If you replaced the coil and still no spark to the spark plugs then you put in a BAD new part or you have another problem, maybe the ignition module is pulsing but does not have enough power output?? You need to verify fuel pressure/delivery and timing set up if it jumped or not, a compression test will show this also if you have low compression. If you need help with these tests please let us know.
Can you post pics of your fuel filter, distributor with the cap off and any other items that may help, if you don’t know how to post pics here, pls post links, thanks.
