Thanks for that. I have indeed cranked for quite some time and tried it with a sniff of starting spray. It trys to start but wont catch.

I have 3 pending codes.

P0193-00 Fuel Rail Pressure Sensor Input High,

P120F-000 Fuel Pressure Regulator Excessive Variation

P1335-00 Crank Not Detected While Starting,

Now if the crank sensor was iffy, would it stop the fuel pressure building in the rails? If the crank sensor was faulty would it fire on easystart?

Yes.

Check the electrical plugs on the HPFP/FRPS and the fuses I mentioned earlier. yµ (idµ - eAµ) ψ=mψ

Well I just tested all the fuses,

Thought sod it and give it even more easy start and it’s running. Bloody thing must of had a shed load of air in the HPFP!

I had done excessively long cranks before but no success. Easy start was the winning factor Smile
