Long crank before start

common cause is that you have low fuel pressure at the start - usually points to the pressure sensor or something that can leak down pressure (ie injectors or other valves) over night. Try this experiment - when you first go to start, turn the key on to position 2( the running position before "start"). listen for the fuel pump - it should go on for a few seconds. go back to off then repeat 2-3 times. see if that builds pressure for a quick start...

Anybody have a parts number for the fuel pressure sensor on a 2011 S80 3.2

Replace the fuel sensor and that worked for about three start ups now I’m back to a long crank and then if I stop and try to started again it turns right over on the second or third try. No weather problems when the car is running no noticeable exhaust. On the second or third attempt the car starts and sometimes will seem like it’s coughing for fuel. This only happens when the car has sat for a couple or three hours. Any suggestions?
