First off I would like to thank you folks for being part of this invaluable service. I came across it only a few weeks ago and used it to get a big screen t.v. issue resolved.
Today I come to you in need of help with my Rover.
1989 Land Rover Range Rover 3.9 v8 4 door with awd. Automatic transmission.
VIN# salhv1241ka343206
I went down through all the rover questions already asked and found helpful info. on some other things I needed as well. There are only two things I question now. #1 is my temp guage shows overheating but when I check the fluid while it is hot it is flowing as normal with no leaks. Is this a faulty gauge?
#2 This vehicle usually fires right up, but recently it had started not wanting to start it would turn over easily but no fire. Sometimes I would try it a couple of times amd them it will go. Or sometimes I wait several hrs and it will start. And it has died twice since this started but fired up immediately after it had died. Then about a week ago I drove it to get gas and it did it again however I have not been able to get it started since. I was turning over easily but my battery has to be jumped noe to get it to turn over still no spark. I have replaced distrib. Cap cleaned as many conections and grounds as I could see. Replaces coil and capacitor( little round metal thing by coil with wire touching the coil the hanes rovers north calls it a suppressor ibought mine at auto zone they call it a capacitor is that the same thing. I am getting no visible spark from coil. And I tested the air sensor thing on the air breather by bypassing the sensor with paper clips just to give it a unbroken crcut but nothing changed. Any help would be awesome. I am in Spencerville ohio 45887 thanks for your time. By the way I am having the exact same problem with mt 87 nissan pathfinder with in 2 weeks of each other what do you make of that.
Answer -
If you don't have any spark at the plugs you just have to follow it back.
Wires bad? Distributor cap or rotor bad? Coil bad?
If you eliminate those parts you have the distributor and amplifier, and of course the power to them.
One of those must be bad for you to lose spark.
AnswerIf there is no spark at the coil you need to check power to the coil, then check the distributor and ignition amplifier.
There are some tests in the workshop manual, which you can get from Rovers North.
As to the temperature, I'd suggest you be sure your own measurement is right before you go ignoring the gauge. I've heard that story before, from guys with melted motors.
Usually, if the gauge says it's hot, it's hot.
