I’ve been struggling to get my car ready for Oliver’s funeral next Thursday. Basically, it wouldn’t start and as it has fuel injection I was trying to monitor the ecu with my laptop. Every time I cranked the starter the ecu went dead. To cut a long story short, I found today that the switched ignition feed that feeds the main power relay for the ECU was only showing around 7.5 volts, and dropping below this during cranking, meaning that there was insufficient voltage to activate the relay. Now I have battery voltage on this feed and the car starts!
For years I’ve had cold starting issues - I wonder if this was a causal factor?
I also wonder what is causing the voltage drop - unless the ballasted power feed to the coil was used to feed the ECU? No time to check it out though - need to put the car back together for the MOT tomorrow.
Cheers Richard
We have ignition!
