If you mean, 12v not present to coil 12+ connection, check the main relay on the r/s firewall, supply's power to injectors and coil. Has five spade conector, pin 30 is battery voltage, pin 87 & 87a need to see 12v from ign switch. The problem will be generally a bad relay or a bad ign switch, the ign switch has a plastic retainer that breaks and the switch pops out, it you have cranking issues along with this problem i would start there.
