91 caravan electrical probs

My father and i were on a road trip and the van just died on us. We were pulling a pretty good hill and the van over heated and we cracked the back head on the 3.0L. We have since replaced the head and gaskets but the van still wont start. We arent getting any fire to the coil,fuel pump, or injectors. No fuses are blown out and i am almost out of patience as well as a van. We are getting fire to the body computer. Could this be an ignition problem?
