Driving on a highway at around 70mph, and it was very lethargic.. barely stayed at 65 mph.. got to the first light and the truck turned off at at about 10mph... coasted to a stop and tried to start it.. first 2 times i could hear the starter spinning, but now its completely dead.. battery's still at full power but the starter just makes a click. I haven't had the chance to diagnose it any further.. just curious as to what some of your experts have to suggest for me when i start trouble shooting it tommorow, thanks..

let me add a bit.. only reason i think the batters good is because i had my flashers on and my remote still works.. but i guess it could be an alternator issue which caused the truck not to turn over a 3rd time. I've also heard that the coil pack won't respond properly if the alternators on its way out.. so could it be that I just have a shitty alternator?

The flashers and remote will work on a low battery- I wouldn't use that as an indicator of whether the battery is good or not. When my DI sits unused for a month, the remote works and the dome lights work, but the battery goes flat enough that it'l just click.
I think you have a bad alternator and it ran off the battery until the battery dropped below the minimum voltage for the ECU, and now is too dead to start it.

I think Syoung could be correct. I Know that the flashers and remote take almost no juice compared to starting the engine. The clicking starter is a tell-tale sign of a dead battery, the fact that it turn over but didn't start a few times is unsuaual. As far as I know it takes less juice to run the engine, than to turn it over while starting. I too would guess alternator trouble. First thing to check is that all the wires are still conected, I have had a cable rattle off of mine before, if that doesn't fix it, and you have a buddy who owns a spare battery, pop it in and give it a go. If the Rangie starts you know where your troubleshooting should start as well. Most autoparts stores will test alternators for free, it you bring it in to them. Checking the oil and coolent isn't a bad idea as a precautionary measure, but I don't think that's your problem.

well.. it blew the 20a ECU fuse under the bonnet.. popped a new fuse in after checking fluids.. and started it up.. made some horribly clunks.. but it cleared its throat and sort of runs normally.. It popped 3 codes which i have written down, 2 of which are Transmission Control related and 1 which was the Engine Speed Sensor.. those are the generic descriptions keep in mind on my obd2 scanner.. cleared the codes.. let it idle for 10 minutes.. nothing popped back up..

tried driving it a bit and it has some hesitation between 750 and 1000rpm.. and gives off a strange heavy vibration.. after that point in the rev it seems ok.. i didn't drive it out of the parking lot.. but i'm sure it'll act lethargic at anything faster then 30mph.. soo.. whats the deal.. my speedo works.. someone said check the harness around the transmission.. and look for a cracked sensor or anything.. but the truck revs funny in park.. which leads me to believe its more of an engine issue.. or something electrical.. I'm going to drain the oil tommorow and replace the spark plugs.. as they're kind of corroded.. any suggestions based on this new info?

btw.. thanks to everyone who's dropping ideas.. rangerovers.net is useless when it comes to advice :D

well.. i made a post on both boards but the advice is very different.. but i'm looking for advice in general so.. i shouldn't bash rr.net so hard.. I've definately used all the informaiton present there to fix numerous other problems.. just seems like forum troubleshooting is quicker here for some reason.. so i digress and shamefully withdrawl my previous flame

any advice is good advice

ECU fuse under the hood, which is a 20 amp.. I got in today and cleaned out the MAF and stepper motor.. and intake pipe.. just for good looks.. and went to crank it, wouldn't even turn over.. tried a few more times and it blew the ECU fuse again.. So I dunno at this point.. i'm kinda stuck.. probably a sensor most likely a transmission one causing a short in the whole system and completely fucking my day up..
