Now that you explain to me better, I give you all the reason, if you have current in the coils then it is the cutting signal that you miss and this is given by the crankshaft or cams sensor, if you have a distributor or delco, you should check the state of the lid and rotor, if it is a distributor and bring inside an account an accountant this is the problem, because it is the accountant, luck and check what you need is the sign of the cut.
