Hold the gas pedal down 1/4" to get it started. After disconnecting the battery, the Engine Computer will have to relearn "minimum throttle" before it will know when to be in control of idle speed and to give you the nice idle "flare-up" at start-up. To meet the conditions for the relearn to take place, drive at highway speed with the engine warmed up, then coast for at least seven seconds without touching the brake or gas pedals. Next, measure the battery voltage with the engine running. If it is not between 13.75 and 14.75 volts, measure the voltages on the two small wires or terminals on the back of the alternator. The engine must be running during those measurements.
