Poor starting from cold or when been left for a period of time.
1 relative compression test 280 amps
2 fuel pressure with scope and within a second we have 1.2 v
3 bench test injectors all ok and show spray pattern and opening good.
4 battery volt drop volts do drop to 8.6 v but rise straight back to 11.8v
5 cam and crank work on scope
6 test fuel 5.8 bio diesel
7 test volts and amps on injectors 48v and only 2.5 amps on clamp but the same when it is running ( does this sound right?)
