Enjoy the old stuff while you can still get the parts - I'm not sure anything modern in properly-engineered anymore. Or if it is, it is let down by the complex FREDs.

The in-tank pump was replaced and that fixed the fault code on the pump circuit but I then got another non-start situation. That turned out to be a pinched injector wire (careless by engine rebuilder) shorting and blowing the injector fuse. Took a bit of tracking down and was frustrating as I had fuel pressure, spark, compression, etc. Further good news is that a good breaker I have used a couple of times has a pair of lw mileage cats for me so they will be fitted by a local independent. That will necessitate removing the whole exhaust from the manifolds back so not a job to do on your back under axle stands. One or two other smallish jobs to do but at least I am independently mobile again.

I watched a wheeler dealers where Ed diagnosed an injector fault on a Range Rover. He put the injector in question in a plastic bottle and turned her over... Less of a fire hazard with diesel I guess :)
