Fuel Pump problems
If your XM won't start but turns over perfectly happily and it behaves as though it has run out of petrol,
you have the dreaded electrical problem concerning the supply to the fuel pump. Try jiggling the
electrical connectors/leads that go under the LHM tank. If it starts then make sure you get someone to
hard wire these connections asap.
There is some talk about hard-wiring all the connectors you find on the XM, this may or may not be a
good ides -there are a lot of then!
One set of connectors that you could try hard wiring (though I haven't yet done it) are the common
earthing blocks on the inner front wings of the car. These are electrically very dodgy and should be
replaced using eyelets and locking nuts and serrated washers.
The rumour is that Citroen skimped on the quality of the electrical wiring, using grade 3 wiring where
BMW was using grade 1 wiring. The resulting electrical unreliability proved to be the final straw in the
XM very poor sales rating -Sales continue to be poor even though the latest XM is a completely different
product in terms of quality and reliability.
Ignition module
I’ve also had this happen on my car. However the problem has been a faulty ignition module. The
symptoms you describe are the same, except there is no spark and nothig going to the coil. Replacing
the ignition module proved to be the answer.
