Hi, 

A 2017 Transit Custom was towed into the garage 2 days ago, reported problems of not starting and when it was going was very sluggish and the three day it was towed in, the dash lights all went out and it stopped in the middle of a roundabout. Tried to start it ourselves, got it going with the booster, was missing and barely firing. Later on decided to try and move it into the lifts and wouldn't start, so had to push it. Changed alternator because the battery was so low voltage and wasn't charging, tried starting it with the booster to get it to charge, wouldn't start. We hadn't seen this van before and the front of the engine is covered in oil. Just keeps turning over, jumped the van off another van and still wouldn't go, put the smallest amount of brake cleaner into the air filter to try and liven it, finally went. Sounded awful and I had my foot flat to the floor on the accelerator wudnt Rev over 900 revs, absolutely no life in it, then it just died, hasn't started since. 

Anyone have any ideas what might b wrong with it. 

Thanks 

Yes, it's probably been driven and driven and driven and not serviced and thrashed and now it's dead
