patient is a 2008 9-5 wagon. the problem started 3 days ago, it goes like this
first start of the day:
- turn key, starts, dies imediately
- turn key, starts, dies imediately
- turn key, starts, dies imediately
- turn key, starts, stumbles, dies
- turn key, starts, stumblew, runs rough, stumble, smooths out runs fine
- turn ofd, turn key starts imediately, runs fine
the rest of tye day it starts runs fine
no cel
no drivability issues. plenty of power, smooth, fast.
these symptoms suggest, to me, that the check valve at the fuel pump is failing. it seems like over night the fuel pressure bleeds off.
but how can i confirm this? i am out of town and i dont have my fuel pressure gauge ...
any other possible causes for this behavior?
