Engines dies will driving. Sometimes will restart immediately, always within 30 minutes. Engine cranks but will not start. Have noticed that the Fuel, Battery and Temp gauges stay at 0 when ignition is turned on. If this is condition engine will not fire. When gauges come up in on position then engine starts. Also have noticed " No Bus" message in odometer if ignition left on foe 10-15 seconds when in no start condition. Have been told that PCM is likely culprit and may be failing. Please help.
