help!!!!! no fuel pressure car wont start
 

my 850 wont start it seems as if the fuel pumps failed or a relay, trouble is i havent got my haynes manual with me so i cant check the locality of the relay`s involved. anyway story so far:

got in car turned key engine struck up and died almost imediately. RAC contractor came out scared the sh*t out of me with his limited knowledege of auto electrics. eventually he decided to check the fuel supply, and was about to fetch off one of my fuel lines with a SCREWDRIVER when i pointed out the pressure test valve on the end of the fuel rail, and found no fuel :(

so now he saying i havent got any relays ill have to tow it home, ahhhh. decided to get him to tow it round the back of the college where i work, idea being if it is the fuel pump i can get the motor vehicle tutors to fix it ;)

anyway any ideas relays to check ect ect would be helpful, oh and the ecu is saying theres no faults.

The fuel pump relay is in the main part of the fuse box i.e. take off the full cover with the 4 torx screws. The fuel pump relay is an inch square & probably green - mine started cutting out when warm & wouldn't start again for a couple of mins. The new one I got from Volvo (£35) was red in colour though - maybe so they could easily spot if it had been changed !! Also, when was the last time you changed the fuel filter - it could be blocked if it's never been changed !! Thats located on the r/h side of the car near the fuel tank.

Hope you get it sorted,

i found out it was the fuel pump, £122 ouch, anyway thanks for the replys, and take a tip from me dont run the tank low with an old car. this is what i did just before i filled up again, then about 3 days later fuel pump died, also when i took the old one out i noticed the filter on the bottom of it was worn as if rubbing the bottom of the tank. this had made a small square hole in the filter a bit bigger thus letting in all sorts of #####.
