Car has no power will not turn over. All lights in dashboard flash prior to car losing power including the mileage light and gear shift indicator lights. All the fuses check out fine battery is fine.

Hello, if your saying it won't even crank, check for voltage at the starter relay circuits, the starter relay is in the power distribution center under the hood. Unplug the relay, use a testlite, see how many hot terminals there are, with the key in the crank position. The circuit for the load side of relay is hot all the time. Voltage for the coil side of relay, goes hot with the key in the crank position.

It may lead back to the ignition switch? When multiple circuits have no voltage, I pick one circuit and backtrack, whichever circuit is easiest.
