.my ford focus diesel 1.8 tdci 2009 ran perfectly. One morning it refused to start. Sprayed easy start thro intake manifold, still won't start. Checked fuses ok What could possibly be the problem

SOURCE: Ford Focus 2003 TDCi Not Starting!

check the diesel filter.it will be clogged,i am sure.Replace it.

SOURCE: engine turns over fine , car will not start.

well the first part of your question i was all ready to tell you to put a new fuel pump in, now not so sure, there is a relay for fuel pump, can you hear pump cycle and relay click? relay under hood you will have to listen close they don't run long maybe a couple secounds, if you don't relay bad. if you do pump could be bad, do fuel pressure test pump could be weak. don't think sunroof and turn signals are related, but stranger things have happend.

SOURCE: 2000 Hyundai accent, ran ok , next morning would not start.

check ignition module in the distributor

SOURCE: Shut 05 Ford f350 diesel off wont start

dies the truck restart once it cools off? it is very common for th 6.0 to have high pressure oil issues on a hot soak. they will run till the cows come home but once shut off they can not build up enough pressure by cranking speed alone to start truck until it cools down and the seals become rigid enough to bridge the gaps they are sealing in the first please. if this is the case. it may be the STC fitting ojn the back of the high pressure oil pump (intake and turbos must be removed to check) or possibly the branch tube o rings have worn. the branch tubes are located under the valve covers and supply the fuel injectors the oil they need to perform their "power stroke"...

SOURCE: ford fusion 1.4 tdci will not start unless the hand pump is used

HAVE YOU CHECKED THE FUEL LINES WHERE THE FUEL PRIMING PUMP IS CONNECTED FOR ANY CHAFFING THEY ARE COMMON FOR CHAFFING BESIDE THE FUEL FILTER WHICH WOULD EXPLAIN WHY FUEL IS RETURNING TO FUEL TANK.
