I have a 88 iroc with a 350 tpi. I put a new intake on and now I have no spark. I fried my msd 6al. replaced it and it ops cks good. I have replaced the ign module, coil, pick up coil, cap, rotor, wires, and distributor. I have also cked the all of the wiring and have performed all of the dianostic cks in the chilton's manual and still no spark. Any help will be appreciated, thanks nate

 

first are you getting no spark at the coil or the plugs if it is the coil you might have burned up that driver in the ecm if it is at the plugs go through everything again its a wiring problem also check and make sure the grounds are all tight on the back of the head

 

Theres on spark at the coil. It could be the ECM. Is there any way to check without getting another ECM. thanks nate
