My 1987 Volvo 240dl left me stranded the other day. I replaced the main fuel pump, fuel pump relay, and some fuses that looked like they had some corrosion on them. The car seems to be running fine now, except the new main fuel pump is making a whining noise. What do you think is the cause? Dirt?
In tank fuel pump not working causing the main fuel pump to overwork? How do I troubleshoot the in tank fuel pump to see if it is working?
