Hi Chris

Thanks for the reply

ign. on the quantity control valve registers 40%,
cranking it goes down to zero
the cam/crank sync comes & goes as you're cranking on live data but on the scope it doesn't drift, it's a clean pattern, the cam just sits as i said at about 6 or 7 peaks before & over tdc identical to the one for a sprinter on the pico library, it doesn't fire when it says sync ok, i've load tested the wires to the ecu, but not stripped out the loom yet!
the ecu has been to ecutesting & declared good
fuel rail pressure 320 to 330bar
