I have an '88 Micra 1.2 Auto, that has covered 20,000 miles. I bought it recently after it had been dry stored for around 15 years. The fuel pump (replaced with an OE new one, just to be sure) can't seem to suck sufficient petrol up to get it to run consistently. When it gets fuel, all is well, but most of the time the fuel filter only fills halfway. Any ideas or suggestions gratefully received!
