I know this is a BMW newsgroup, but I am desparate for help.
The VW has an electric pump external to the the tank My friends car will run poorly, then die, then start back up.
A mobile mechanic did a very quick check and said the fuel pump was bad. He did not use an electric meter to test any resistances and I am wandering if maybe he was a little too quick in his diagnosis, to make his $40 easily without getting his hands dirty.
I am wondering if the electric connections could be dirty. Or maybe it is just the fuel filter.
I am wondering how could he really know the electric pump is bad, without an ohm reading???????
Thanks in advance for any help.
