is the Batt a full charge are your +Pos_ -Neg wires making good connections. if all is good then did you move the timing by chance? Or did you make sure all the coil wires are on good. Did you hook up the HEI power wire on the coil, if you did not it will crank over but will not start. Re check all simple things that you did first. Did it run before you did work?
