Thanks to the folks who gave me advice about replacing fuel injectors. I replaced the one that I suspected was leaky last night, and it solved the problem with the '95 Disco cranking too long when hot. Involved but fairly straightforward job with just a gotcha or two.

How did you diagnose which one it was??? And does anyone know if any aftermarket or alternative injectors will fit that dont cost a fortune??

I went through a whole string of diagnostic things to convince myself that it WAS a leaky injector that caused the hard cranking thing, but finding which one was easy... I pulled all the plugs, and they all looked fine except one. #5 was sooty, including soot near the insulator tip. This is a definite sign of a leaky injector. The tips should be clean, with a light brown tinge that becomes more distinct with age.

There are a number of co.s rebuilding injectors, but I couldn't find one that did LR. Some have said they can be cleaned ultrasonically, like jewelery...but that presumes pulling them, sending them out, and having the truck out of commission in the meantime. I got mine from Rover City, 800-274-4830 for $95 each (got 2). Some web sites list as high as $350 each, even though I believe LR dealers only get $150 to $180. I don't think there are any aftermarket ones.

I reused the o-rings (pulled out the left bank, leaving the right ones in)... the new ones of course had new o-rings. Put silicone grease on them before re-insert. The main thing to be careful of is to ease the injectors back into the rail one after the other, going back and forth, as they will tend to angle, which could gouge an o-ring. It was a bit of a b***ch to get them all the way in...pounded *gently* on the rail with a copper mallet. E-mail if any questions.
