This is starting to be one of those times where I'm getting frustrated with having a Volvo. Last week drove the 300 miles or so to the folks place. While there changed oil, air filter. Went to go home and car was bogging down and stalled. Turned around went back to folks place. Car would start and stay running at idle, on ocassion it would stall while at idle. If I gave it gas hard and let off gas it would stall and kick back in. under hood fuse ok, both pre-pump and pump ok, new fuel filter ok, found crack in sending unit return line. New sending unit installed. problem solved???? Seemed to run fine and decided to drive back home and died after a hour of highway driving!!! Called good old dad to come get me. On side of road took of gas line off right before it goes to the injection manifold and sure enough there was fuel coming out. Hooked it back and drove it back to my folks place. Stuck again!! Is there some kind of fuel pressure regulator??? PLEASE HELP ME!!! I am losing love for my 240!! Help!!! Thanks...mike
