Hi All
I'm not 100% sure of the netiquette associated with providing an update to a recent thread. I'm sure, if you're like me, that you don't read old threads, so I thought I'd make a posting under a new subject.
If you can recall, I have an old BMW that has an intermittent starting problem. It is not frequent, but has happened again. I'm pretty sure now that it relates to a less than 1/4 full tank. Certainly, in answer to another poster, there is NO cloud of black smoke when it does start. This would presumably indicate that no fuel is getting into the engine, and may suggest a pump or filter problem.
The local garage could not identify a problem, but did notice that there was a new fuel filter fitted. I guess this was at a BMW service (I'll ask them next week). My FIL also noted that their BMW (diesel) had a similar starting problem that had a fuel pump relay replaced as a first guess; later the whole pump was replaced which cured the problem.
Would this problem suggest that the fuel filter or pump is at fault? Why would a faulty pump only show up as faulty with an empty(ish) tank?
