My 2000 Odyssey is cranking, but will not start. My mechanic started by checking to see if there was ignition in the spark plugs before proceeding. It was learned that none of the spark plugs have ignition. After using a scanner the Crank Shaft and Cam Shaft sensors did not send out a faulty code. There is an EGR code 0401 even though it was just replaced. There is also a Catalytic Converter code 0401. WHAT could cause an ignition failure in all the Spark Plugs? Oh, on 2/10/12 I had the fuel system cleaned at a local shop which used a Motor Vac machine to clean out the injectors. The following day on 2/11/12 my car took a vacation and did not START! Could the cleaning be related to the lack of ignition?
