ems has stopped lighting up on dash and glow plug light failed at same time no voltage at glow plugs, fuses all tested and ok,
engine will not start poss due to being unable to read any fault codes
and unable to carry out ecu reset which will be necc as I have just replaced suction control valve , many thanks Ronnie.
Anytime the engine management light quits working you need to start by checking for power going to the ECM. If there is power going to the ECM this means the ECm relay is operating and you may have an issue with the ECm itself.
The ECM and relay should be at the passengerside footwell.
thanks a lot ,is the relay the one in the wiring harness that connects to the ecu
