I've got a 1991 240 sedan, been having problems with the fuel delivery ever since I bought it from a guy for $500 w/ only 101,000 on it. Duh, should have seen that one coming. I can't get this thing to start up consistently for anything. I've put in a new fuel filter,switched out the fuel pump thinking that might be weak ( put a known good one in from my old 740 Turbo), I know it's not the same but it worked, I changed out the fuel pressure regulator. Bottom line- sometimes it starts up and runs fine, good acceleration, idles fine- you'd never know anything was wrong with it. Other times, can't start it-prime the intake w/ gas to see if it fires- it'll run and die. Other times it starts and I can run it down the road for about a mile and it just cuts out- usually restarts after this condition though. Please help- I rarely need to ask advice for my small fleet of older Volvos, but I'm stumped by this one. After a year of off and on driving with this thing, it's getting old.
