Hi
Had a quick look at this just before leaving work this evening. Car is running on 2 cylinders 1 & 4 with expected injector pattern on scope (Amps). Cyls 2 & 3 have no pattern either volts or amps. I am going to load test wiring tomorrow but was wondering if ECU injector capacitor / driver failure is a common fault on these ECU,s?
The only code stored was for glow plugs (no surprise ) and idle rail pressure was 380bar. The car starts well considering and if I induce a substitute fuel supply it idles well.
