A friend of mine has a 90 GT 5.0. The other day he was driving it to town when it cut out hard but it ran fine to where it was going, but when he went back out it would not start. It turned over but but no fire to the plugs. We had the coil checked and put a new module in it but steel nothing

We are geting power to the coil but it is not geting to the plugs. Any ideas?
