Ok, well I have a 96 Land Rover Discovery, which by all means is a great car thus far. Currently I have had problems when the outdoor temps drop below 36F or so. The car turning over sounds like it is trying to throw a rod and is hard starting. I can let idle to warm up and once on the road when you brake at a stop sign it will die.
Restarting is even worse as it will chug and chug and after giving it gas it will eventually turn over.
I have replaced the fuel filter, plugs, plug wires and what not to no avail. I had another prognosis that it could be something to do with vacuum lines. My now understanding is that maybe I have a bunk fuel pump an electrical short, or even possibly bad injectors. The cars around 109K on it with around 20k on the rebuilt 4.0 V8.
I will appreciate any input what so ever.

>>>> http://www.autozone.com/...artTypeResultSet.htm <<<< Click on that. This shows both a cam interupter sensor and a crank sensor which would have everything to do with timing which I think is the problem a guess for sure but if timing was way advanced it would react trying to start and could stall. Also could make sounds with the starter fighting an engine that fires way before TDC.

It's a guess. The cam thing is over $200 and crank sensor about $75. Get a full code reading and see if that helps even if no light is on. The tune-up items aren't a total waste but tossing lots of parts isn't the best fix.

Vacuum leaks wouldn't be much of an issue at cranking to just started time but they are worth looking for. It's the fact that it makes a noise that concerns me,

Re: 96 Discovery Problems	Sign In

Thanks Tom! I never really think of simple things such as timing. I usually blame everything on some electrical or computational item. One more thing to note is that after first initial starts and once it gets going, I don't have the problem anymore. It is definately a first thing in the morning situation, even after 5-6 hours of cooling down in the fridgid northern Nevada climate I turns over like a charm. Really embarassing when you are getting off the freeway and your car dies on the way down. I will look into some more thanks for the link!
