I did see a you tube vid on a focus that had a bad ground in the bay and once cleaned it was fine. Symptoms are identical to mine so fingers crossed Quote Link to comment Share on other sites More sharing options...
Mita Posted March 12, 2017 Author Share Posted March 12, 2017 I've also been advised to disconnect one sensor at a time and see if I get my mileage back or the engine cranks. Will try this too carefully. Would rule out a rouge sensor causing the PCM to shut down? Quote Link to comment Share on other sites More sharing options...
G B L Posted March 12, 2017 Share Posted March 12, 2017 When you clean up the Grounds. Check and see if the scan tool Read Gets info from the Pcm. You will get to the bottom of this I am sure . It might take 40,000 Euros but you will not need them soon anyway! Mita 1 Quote Link to comment Share on other sites More sharing options...

Mita Posted March 14, 2017 Author Share Posted March 14, 2017 (edited) UPDATE ! I thought it would be good to post the latest for all interested parties. Been trying to juggle looking at the van around work hence the slow update. I re installed the PCM this morning. I then cleaned up several grounds that were awful. Confident this was my issue I put it all back together, turned the key and ..... NOTHING!! :( So I tried each sensor by unplugging individually but again no joy. So next I decided to have a proper look inside and underneath the engine fuse box. I noticed one of the cables by the moulded plug had a green powder on it. Knowing copper turns green when it oxidises gave me new hope. On closer inspection the cable was split and it was just the insulation holding it there. I traced the cable back to the fuse board (it was black and orange) and would you believe it was for the power up relay (R8) . Unfortunately the cable broke right at the moulded plug. So I cut back the loom slightly and crimped a plug in to the cable. I then ran a new cable from there in to the fuseboard and cut the black and orange cable from the relay. I then crimped in a plug there and connected. So effectively I've by passed the moulded plug and made my own . Put it all back together and it's started! Hopefully this thread will prove useful in the future for others. Many thanks for all the help from everyone who posted .
