I have a problem with my Ford Escort Diesel 55 Van N reg 1996 non turbo its done 90000 I have change the glow plugs, heater relay, diesel heater relay, pump primer plus fuel filter all new parts. When I start the van in the morning its start well but is very lumpy and sort of misfires this is solved by giving it a quick rev, but even when warm if I start the van without either keeping my foot on the pendle or giving it a quick rev its lumpy on ilde is there a air leak problem or with the diesel injector pump? Should I change the fuel pipe bewteen the primer pump and injector pump with a non return valve I think fuel might be running back to the fuel tank would this be the problem or is there other issues? Has anyone had this problem?
Look forward to a reply.
