Landrover Discovery 3 crank no start

Post by Darren Fraser »

I am really struggling with the injector waveform on this vehicle and am asking if anyone can tell me where Im going wrong.

This engine was overhauled and has been struggling to start since. It cranks,and tries to start almost as thought there is not sufficient fuel, fuel pressure has been checked and is ok. I thought I would start with the injector test and attached is the closest I can get to a triggered voltage/amperage signal. Im reading the current here at about 750mV which equates to 7.5A? But when I scope my test light (0.2A) this current reading is more like 0.7A??

Have i got something incorrectly set in my settings? Im using a ACD-212.
