Ok this weekend has been first time off work with family for some time so not had a lot of time to spend on truck.
Only thing I did was video engine from cold.
but didn't upload as don't sound half as bad on video.
There's no air in fuel system.at least priming pump was rock hard.
Can't be bothered on bank holiday weekend do the jobs I can do until running issues are resolved.
All connectors and wires have been checked cleaned and all looked good.
Need eml off before I go any further.
As said done paper clip.diagnostic pc etc.
Last hope of getting eml off is disconnect battery to try and reboot ecu.
And can go from there.
