alright i have a major problem and cannot seem to figure this out so maybe some help. a buddy of mine and me put some headers in my car the other night. now it was a nightmare for a few different reasons but we finally got it on. after all this i went to crank it up to here it roar and to my luck it didnt start. it cranks over fine but for some reason its not getting spark. we checked the obvious things such as grounds and fuses. so we went on to the bigger things such as ignition coil and crank sensor. neither one of those was the problem. so im completly stumped. i have asked a couple friends of mine that are mechanics and they told me to check the same things that i already check. please tell me there is something i am over looking any suggestions?
