My Mercedes-benz GL550 08 Not Starting When The Engine Get Hot. by abidemidare: 8:02pm On Dec 25, 2020
Compliments of the season. Mercedes-Benz GL550 08 not starting when the engine get hot, but start once the engine get cool like 2hours. I have changed kick starter like 5 times, battery like 3 times, it really giving me sleepless night, now my mechanic is saying I should change the alternator. Please house, what could be the problem.

Thank u all

Run a thorough detailed diagnosis that car, but I'm leaning towards a failing pump or coolant temperature sensor.

There should be a code stored, it will show up with a good scanner, if your coolant sensor reads high when not starting, check again when it starts and that will be a proof of concept.another culprit is ignition coil

Change your mechanic



Run a scan on that car instead of throwing expensive parts at it like an angry housewife. The only person benefitting from that trial and error is your mechanic

fuel pump. Also check your temperature to make sure car isn't overheating.

Check the grounding wires for the kickstarter. Check the termination point and the wire itself. Check the relays as well.

Did the rewire do a compression test?
How did he arrive at that decision?

Crank sensor

A crank sensor is an electronic device used in an internal combustion engine, both petrol and diesel, to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters.


Your engine is good ... Change crank sensor abeg

Re: My Mercedes-benz GL550 08 Not Starting When The Engine Get Hot. by IkpuMmadu: 8:45pm On Jan 02, 2021

There are two things

1. Crank sensor
2. Fuel supply system (fuel pump ) but that should be. Remote one..... Do change your crank sensor first

Problems with the Crankshaft Position Sensor (CPS) on Mercedes-Benz cars are fairly common. If you have been experiencing stalling or no start conditions, a failed crankshaft position sensor is often the problem. Your CPS may have failed if the engine cranks but it will not start. At first, you may experience no start conditions intermittently. As the crankshaft position sensor fails completely, the car will no longer start or will die when you are driving. Starting problems are initially random, but more frequent when the engine is hot. Other symptoms of a failed crankshaft position sensor are poor acceleration, engine vibrations, poor throttle response, bad fuel economy, hesitation, engine stalls. The engine starts if you let it cool down. If you are stuck on a parking lot and the car will not start, let the car cool down at least 30 minutes and then try again.

You can still call Yemi +2349045410788 he is good also...

Tell him you are suspecting crank position sensor , I hope you have all the parts you removed in your car ....

Crank position sensor is a common benz problem and it's not expensive not even up to 6k...

It's behind the engine near the kick
