hey guys, im looking to buy my mates 2001 mk 5 fiesta zetec s, its been sat for three years untill yesterday, rust aint that bad on it,he said its got 4-2-1 de-cat manifold, puma injectors and airflow meter/airbox.......the prob is it wont fire up, there's power, everything works,it try's to turn over,could this be the fuel pump? if so is it a tank out job on the fiestas? ive never owned a zetec s, ive had an old 1,25 zetec se, how hard is it to do? pretty handy with a spanner, i've checked the fuel pump fuse and relay and its all fine, it was parked up running with no problems.....any help would be great, and im sorry if this is in the wrong section, cheers all.
