Hi everyone! This is my first post. I've owned two 2002's and a '79 320i, and I found a '90 325 very clean and nice at a very good price. However, it has fuel delivery problems. I've heard of this prob on these cars. Can anyone give me some specific advice? I'm really looking for a newer model, but this one would be a steal if I'm confident the repairs won't be overwealming to my wallet and nix the deal. Thanks!
325 fuel delivery prob
- Thread starter starmountainkid
- Start date
I don't know of any specifics. In general, I've experienced the following fuel problems on older cars:
1 - Dirty fuel filter = low pressure to injectors/carb, similar to weak fuel pump below
2 - Bad check valve = won't initially start hot or cold, starts easily after 5 - 10 seconds. Usually more noticeable after the car sits for a few hours.
3 - Weak fuel pump = starts OK, won't run well as RPMs increase (fuel starved)
4 - Dirty injectors - hard to start, runs rough, poor mileage
