Very true CasaLobo but I assume that as a long time Talk Morgan member PhilipNZ would have replaced his standard fuel pump for a more reliable Walbro one long ago...... As you say, always worth a check of the fuel pressure at the test point, particularly with those codes.
Thanks guys - I'll check that. No I haven't replaced the fuel pump, I've never had an issue with the car until the rollers failed at 10000km
