My 1976 245 wagon has always started rough in the mornings but did always start. One day running errands it would not warm start. I put starter fluid in the plugs and it ran. This happened several more times. I brought it in to a volvo shop and they replaced the fuel pump relays and said this will solve the no start when warm. They said the morning rough start is probably due to a faulty fuel pressure regulator. After the fix the car still would sometimes not warm start. Then last week it died. I cannot get it to run at all. I have tried starter fluid which almost makes it turn over but no dice. The mechanic says he cant be sure what the problem is but suggests I have him do the pressure regulator to the tune of $400. Any advice? Does $400 sound right for the fix. I am a low budget student and if i do the fix and it does not run I am sunk
Thanks for any advise
