air in the fuel system?


Asked by Oct 04, 2016 at 07:29 PM about the 2009 MINI Cooper Base

Question type: Maintenance & Repair

Hello,  I just changed fuel feed inlet hose pipe (was broken and gas was spraying at a crack).  The car was running fine with the broken hose.  I changed it to the new one and it does not start.  I do not see any leak and the hose seems to fit perfectly.  

My question is:  do I need to get the air out from the new hose somehow because otherwise there will be no sufficient fuel pressure for the injection sensor to allow to start?

Or just computer somehow noticed that the fuel system was open and something needs to be cleared out from the computer to start?

I just find it weird that it was working and with the new mini hose it does not start but there is no evidence of leak or any loss of fuel pressure by the new hose.

Any ideas?

One more idea to add to the story. I disconnected the battery while I was doing the change. Could that be related to the issue?
