Anyone know how to fix, needle does not move at all, stays at empty

 

I'd start with the fuel tank sending unit.... A quick google of "volvo 740 fuel sending unit" got this Youtube vid.... (and other related board posts)


You can probably find some guidance on how to test connectivity/resistance of the unit itself via google or search for similar threads on this board.

It could also be the gauge, a connection point , ground wire, fuse so you may also want to look at the wiring diagram at volvowiringdiagrams.com

Guys, thank you for the help.
