mjfuture Posted August 25, 2012 Share Posted August 25, 2012 Not sure about the gas problem but for the starting and idle its probably the engine wiring, but first check the plugs and if some of the injectors are out of work. Hope I helped, If not reply and I'll ask the experts I know Quote Link to comment Share on other sites More sharing options...
Steve Posted August 28, 2012 Share Posted August 28, 2012 The pressure in the tank is normal. It is meant to do that. It is actually sucking air in as the fuel is displaced. Quote Link to comment Share on other sites More sharing options...
