The car was starting and running perfectly but last week took dogs out and upon returning to the car it wouldn't start, cranked over until battery gave up and had to get towed home.
The car has plenty of fuel in the tank and I've replaced the filter, I've disconnected the fuel feed line under the bonnet and there's a short bust when the key is turned so assuming the fuel supply is ok upto that point. I've connected a scanner to the car and it's maximum pressure is showing 970psi and upon cracking that slowly drops before peaking again around 700psi? I believe this should be around 5000psi min to start, very strange to have had no prior warning of an issue.
Any help much appreciated

you should get more than a spurt when you put the ignition on when you take the pipe from the tank off the main pump . it should gush out .... there is 5 bar pressure in there from the tank pump .
Yes the fuel pump is driven directly from the CEM ....
