1998 Land Rover Discovery Questions & Answers
2006 Chevy Impala stuck in park
When you turn ignition on it releases a cable that is attached to the shifter also the shifter has a solenoid attached to it that is released when you step on the brake. Both times that I had the problem of button stuck and cant shift out of park the solenoid was sticking and wouldnt release .
1998 land rover discovery 1 dies in water and wont start.
From what you describe the pump itself is probably OK or it would not run at all.
You obviously still have a water problem in the pump wiring or in the pump itself. Get under the vehicle and trace the wires all the way back to the engine bay, starting at the pump. Dry everything you can reach with a hairdryer (not a heat gun - too much heat). Once you figure it is all dry, spray every connection with electrical parts cleaner.
If this doesn't fix the problem you may have to consider replacing the wires - not as difficult as it sounds.
Voltage at fuel pump
fuel pump voltage should be 12 volts or as near to it. relay has a voltage drop, 5-6 volts means there is a bad connection, faulty earth or a connection wire, could even be the relay,, check the earthing wire follows from the pump or make a new earthing connection. clean the earthing points on the shell from the batter, put some grease over the connection when clean and tightened,
Idle speed is shaking up and down
black exhaust = over fueling
so there is an injector problem either in the seals under the injectors or in an over pressure problem
The sensor that controls the air / fuel mixtures is the heated oxygen (HO2S) that is in the exhaust manifold before the cat converter and that often fails and so the ECM cannot control the injector operation
have the fault codes run before you waste any more money replacing items not connected to the problem
Overheating
I would first get a OBDII scanner (you can get a Bluetooth one on ebay for 15$) run that and look at your error codes. It sounds to me like you have a short that is causing your gauge to malfunction. There is nothing that would directly correlate the headlights or the e-brake with the temp other than the headlights causing a short that is the same when you pull the e-brake and the brake lights are causing the same type of problem in the wire harness.
Speedo does not work , any thoughts would be welcome
The 1998 TDI uses an electronic speedo. Assuming all the other gauges on the dash are working, then it is not a blown fuse. In this case it is either the pick up from the gearbox, the speedo itself or the wiring in between. The easiest way to check is by substitution of the speedo or the pick up one at a time. If this fixes it then the wiring is OK. If it doesn't fix it, then go looking for a wiring fault. Given the age, the wiring behind the dash can fail either by open circuit or shorting, so I usually just run new wires if I get a fault in one.
