2002 GX Nissan Patrol , Mystery

[Adebayor Bloomfield]

Hi Everyone, I am new to this Forum. The Mystery is, This vehicle has done 300.000 KM it has presented a real problem, it has a new starter, new glow plugs , new heavy duty battery, On a cold morning it will not start the click of the relay is heard ,the glow plug light is on and when it turns over it turns very slow like the battery is almost flat. roll it down hill and instant start then turn around ,park and turn off and it will start and run all day perfectly,does anyone know if the relay can appear to operate but not be sending current to the glow plugs and why the starter turns over slowly all on a cold morning, a jump start makes no difference. Or maybe is it better to sell it via sca.auction and save tons of time?

This sounds like a strange problem you're experiencing with your vehicle. It could potentially be an issue with the glow plug relay or the wiring connected to it. The relay is responsible for sending power to the glow plugs, so if it's not functioning properly, the glow plugs may not be receiving the necessary power to heat up and start the engine.

It is also possible that the issue is with the starter motor, which may be having trouble turning over on a cold morning. This could be caused by a variety of factors, such as a weak battery or a problem with the starter solenoid.

It would be best to have the vehicle inspected by a professional mechanic, they will be able to run diagnostics and diagnose the problem more accurately. It's also recommended to check the wiring and connections to the starter, battery, and glow plugs, as well as the starter motor itself, to make sure they are all in good working condition.

It's worth mentioning that sometimes, the problem could be related to the engine oil viscosity in cold temperatures, that can make it harder for the starter motor to turn over. Make sure to use the recommended oil viscosity for your vehicle and the temperatures in your area, and check the oil level as well.

It's also important to note that the Nissan Patrol is known for its durability and longevity, even with high mileage, so it's possible that with the right diagnosis and repairs, your vehicle will be back on the road running smoothly.
