DD15 wont start despite good battery and starter
I have a 2012 DD15 engine. It wont start despite a strong battery and starter, there are no engine warning lights or codes.
My local mechanic (not a dealer) tried checking the fuel lines and changed the fuel filters, primed it, but no help.
When ether (starting fluid) is sprayed into the air intake the engine will fire like it is going to start, but as soon as the spray is stopped the engine stops.
I think it must have something to do with the fuel pump, or what used to be called a primer pump (or lifter pump) but there are no warning lights or codes, so any ideas?
Is this a worthwhile discussion?
