Watch this video from 32mins in near the end, Mike turns the internal cog.

Timing may be out. Chain might be out a little.

Try disconnecting fuel line at FPR and see if you get diesel there.

Could be ecu problem. Check the socket for oil, injector harness can leak oil back.

Is the fuel pump running, filter ok and system bled, fuel pressure regulator ok, TD5 engines require a really good battery to spin them over fast enough, is the battery up to the job.

Grip the bottom of the front of the base cushion and pull up sharply, then slide forward and lift it out, refit by sliding the two rear lugs into location holes and press down on the front of seat base to snap back into place. No tools required, the battery box cover has a latch at the front...

They are more than scratches, more like gouges and looks like major damage as far (as turbo blades are concerned), a turbo specialist would throw that cartridge in the scrap bin, you may get away with running it for a while but I would think the bearing will suffer damage before too long. If it...

Did you put the damaged turbine cartridge back in, turbine blades are very finely balanced and any damage will cause serious trouble if you continue to run it like that, I would not risk driving it like that. They can spin at upto 200,000 rpm.

The first thing I would check are the air hoses to the turbo and to and from the intercooler and the intercooler itself for leaks.

Next time it happens, take off the fuel filler cap and listen for air being sucked in, the vent may be blocked and causing a vacuum preventing fuel from being pulled out, try starting with the filler cap removed, (worth a try)

Earth fault, its always an earth fault

What model, engine, year for correct wiring diagrams.

Wrong key, does the key have "fuel" stamped on it.?. The fuel cap has its own individual key.

I would not put Continental tyres on my push bike, they are all rubbish and wear out very quickly, utter rubbish, my new Volvo XC90 had them on when I bought it, I could not wait to get rid of them. My Defender has General grabber TR tyres and they are a good all rounder.

Have you got plastic covers on the seat recliner handle, they are usually missing and result in snagged clothing. https://www.ebay.co.uk/itm/223519375640

As long as you lubricate the seals with brake fluid and a bit of grease on the piston and spring they should last as long as any expensive one's

"How much" I replaced my 2004 TD5 clutch 90 master cylinder about 6 years ago for around £12, had no problems with it, prices have gone up a bit but £15 gets one, loads on ebay, this link is just one of many. https://www.ebay.co.uk/itm/290969684513 One of Mike's video's,

I refitted my EGR and Cat as the exhaust was embarrassingly smelly for normal road use and school run etc, not smokey just smelly, it is very much improved, cleaner and sweeter smelling and honestly there is hardly any difference in performance.
