So I’ve checked the purple relays again:
Checked with both relays fitted and the fuel pump starts and there is plenty of pressure at the rail but the car did not start.
I removed the fuel pump relay, turned the ignition on and the fuel pump did not start and the car did not start.
I bridged the fuel pump relay terminals (plugs 86 & 87 on the relay) and the fuel pump started but the car did not start.
Carried out the same procedure for the other relay and fuel pump started during each test, the car turned over on each test but the car did not start.
I checked the fault codes during each part of the test and here are the screens:
Ignition on and fault code refresh
Refresh list after cranking
Turn ignition off and back on then refresh list
Fault codes were the same regardless of the status of the relays.
Still no luck, anymore suggestions please
