SOURCE: 1993 mercedes sl300 convertable

Hi,
The early 300 SL suffered from dodgy HT leads and spark plugs if not regularly maintained, the problem with Mercedes Benz though is that the cars have so many features that it is almost impossible to diagnose without seeing the car. Some things to try (in this order) are : - Spark plugs, Ht leads, remove and clean Distributer Cap, replacement of HFM sensor (common fault), if none of these help then faults have been known in throttle valves and fuel pumps/filters

Happy fault finding

SOURCE: my mercedes e300 (1989) starts and runs ok but then cuts out.

I had a similar problem with my 1986 300e , which got progressively worse until the car was no longer driveable, I changed out the fuel pump relay and the problem went away.

I had the same problem, took to a benz dealer, it was the fuel pump relay, cost for repair $200.

05 c240 turns over won't start


most likely you have a bad crank sensor or fuel problem you need to check fuel pressure ,if you have enough pressure ,most likely you need crank position sensor,if you don`t have fuel pressure ,it might be your fuel pump relay or the pump, i would start with the relay first very unexpensive. you can also hear the pump if it`s working by cranking the engine and listening rear of the car for a humming sound .
good luck

Car won't start


You will have to pinpoint what the engine is missing...
- Spark
- Fuel
- Compression

All three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the engine to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should.

Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition. Be extremely careful when doing these tests.

Were to start troubleshooting on a 2001 Mercedes Benz ML 430 cranks but will not start


First try to squirt some starter fluid in air intake, then try and start , if fires and runs for a split second then dies, most likely possible fuel pump bad. Thanks mike. Please let me know on results of starter fluid, then we go from there.

I HAVE A 2001 MODEL WRX EJ20 WITH AN INTERMITANT SPARK FAULT,PROBLEM STARTS WITHIN APPROX 30 SECONDS AFTER START UP,FEELS LIKE A MISSFIRE,IF I TAKE ONE OF THE COILPACKS OUT YOU CAN SEE THE SPARK GET WEAKER...


From all the things you have said and done are you sure that it is spark related and not possibly fuel related. Change the fuel filter and check the fuel pressure.
