Hi my car is a 1988 2.0L turbo CD which has covered 180K KM. Going to work my car was misfiring really bad, even when hot. When idling I could hear a noise from the boot. The next day it wouldn't start as no petrol was getting through so I suspected the fuel pump, however this seems to be working OK. The pump relay and system relay seem to working OK too. The car won't start unless I ground the earth terminal at the back of the pump relay. What do you think the problem is? Dirty earth or maybe the pump after all? Or perhaps the ECU?
