Volvo: MY VOLVO S80 WONT START, volvo s80, fuel pressure

Question
I OWN A 2005 S80 THAT HAS BEEN NOTHING BUT A PROBLEM LAST NITE RAN FINE TODAY WILL NOT START PLEASE HELP

Answer
Will,
Are there any fault codes stored? Do you have fuel and spark while you crank over the engine? What is the fuel pressure? The engine will not crank over? Is the shifter aligned in Park? Is there an alarm in the car? Use the key in the front door to turn off the alarm. Do you have a good battery that has plenty of power or is it getting weak? Test the charging/starting system.
