Arvaukseksi menee mutta voisiko olla DME rele?
Jos oletetaan että bensapumppu, sulake ja pumpun rele ovat ok..
DIAGNOSIS
The order of electrical flow through the fuel delivery system is fairly simple: The DME (ECU) sends a signal current to the main DME relay, which in turn feeds the signal current to the fuel pump relay.* From there, the current flows through the fuel pump fuse before heading down to the fuel pump. This whole circuit is complete and live whenever the ignition is cranking or the engine is running. To summarize:
DME--> DME relay--> Fuel pump relay--> Fuse #18--> Fuel pump.
