f150 No spark
Ok, I have done every test I can find to find out why I do not get a spark. Back ground, 1996 f150 with 351 just quit running. I have replaced the dis, checked the ign coil (even replaced with a working one), test the icm, tested bad replaced, and unplugged the pcm and still I get no spark. This is my 16 yr old daughters truck. Had a similar issue when we first got it. That was a dis. That is why I changed out the dis this time, thought it was same issue. I was wrong. Any help would be greatly appreciated.

Update, I continue to try anything I can find on the forum, but having no luck. Put 1 cylinder at top dead center to make sure everything aligns properly. Thought maybe timing chain. But rotor points to #1. Doubled checked power readings at coil, 12+ in, ICM same. Just not sure what else can be checked. I would appreciate any help/suggestions.
