i have a renault trafic dci 100.it will start and tick over but wont rev.if i put the ignition on and undo the bleed screw diesel will come out,do it up again then it will start and rev ,its bit slowly untill 2500 revs and then it revs on fine.it seems to be electical because if i flick the ignition off and on when reving it wont rev again untill i stop and bleed again,if anyone has had and solved this problem i would be greatfull for advise

had same prob. tried all usual elec parts over 6 mounths. then took of diesel filter and found it clogged with muck replaced with new one,,, big big improvement. starting to slow down again. will have to take tank off as it must be full with muck...

have you tryed running it with the air mass meter of it.if it still dosnt rev put amm back on. allso check your low pressure vacum pump at the side of your egr valve.has two rubber pipes connected to it.
