CM11 Santa Fe Fuel Issue
#12
Batt to Start cable .16v
Batt to charge/alt cable (in fuse box) .13v
battery- to engine (lift lug) .3v (dirty contacts due to paint etc. But Voltage drop doesn't seem to be too bad)
there's 3 cables on positive battery post, 1 to starter, 1 from alt fuse in fuse box, where's 3rd located? I really don't want to pull the loom to bits just to find where it goes lol.
is there a way I can feed correct voltage to solenoid on high pressure pump to see if things are willing to build up to pressure & start? Just trying to confirm a voltage issue as I've been chasing this problem for months.

Just for the fun of pulling things to bits. (And didn't the engineers HATE mechanics the day they designed that set-up).
I've removed crank sensor, cannot get any ohms readings across any of the pins. Including while waving a spanner across the pick-up, tried waving a magnet across the pick-up and still no continuity.

Update,
crank sensor made no difference.
Wiring all within spec.
all ground points now cleaned & tight.
I attempted to upload a video so you could see the fuel pressure whilst cranking but it won't allow the upload.
Daytime temps in mid to high 20's °C
Nights down around 5°C
best way to check for signal to injectors? I'm doubtful all 4 injectors would fail at once but it's not unheard of.
Can I test fuel pressure OTHER than trusting the sensor through OBD?
Cheers
