Subject: Re: [928uk] More trouble
It is possible for a fuel pump which is on its last legs to be =
finished off by being run=20
very low. I suspect it is more to do with lack of cooling than picking =
up any crud. But it=20
is unlikely for a dying fuel pump to get better even tem****arily.
It is quite easy to test though, just measure the quantity of fuel =
coming down the return=20
line to the tank with the fuel pump running.
Oil level warning coming on during extended cranking, or just after =
stalling, is normal.
Alarm going off is probably a totally unrelated problem, but be aware =
that some people=20
wire immobilisers in to fuel pump circuits (into the actual supply to =
the pump) and=20
immobiliser relays aren't sometimes man enough to supply the current =
for many years.
Easy check is to run 12 volts direct to the fuel pump. Make sure you =
have no leaks, as you=20
will get a spark when you disconnect it! Probably safer just to =
measure the voltage at the=20
pump while its running.
