My disabled friend recently bought a 91 740 wagon that looks almost new. 100,000 mi. She just called and asked me about this; a couple of days ago the car had been running fine, she was driving on the freeway, took an offramp and at the bottom at a stop sign the car died. She tried to start it and it did, and it ran and now seems to run fine. She took it to a mech she knows who supposedly knows Volvos and he ran some tests. He told her this "the fuel pressure is fine, but the pump sounds like it's running slowly so we think it's the fuel pump." He wants $350; $300 for parts, for a pump so I suppose that's the main he's talking about.
This makes no sense to me. It didn't to her either so she didn't go for it. A fuel pump would not still be running fine a few days later, and wouldn't die and restart this way either I believe.
Can I get any guesses as to what may have happened? I haven't seen the car yet, I'm going on Sat and see if I can get any clues. I'm going to look at the intake, vacuum lines, throttle linkage, air cleaner, obvious stuff. I got some great help here a few weeks ago about my 90 and the throttle body and so on.
Thanks for any notions.
