SOURCE: mercedes E300 turbodiesel, 1999, is poor to start

Yes sir , you have a failing valve, soon it will snap in two....please have your head checked. You can do this yourself by placing a long-handed screwdriver , business end down to each cylinder while pressing your ear to the handle(while engine is running)...you will notice a definite difference when you hit which cylinder has the bad valve. Also makes sure the egr valve is clean and your exhaust recycle valve is not stuck.( located in the crossover pipe)

SOURCE: 4g93 gdi engine starts wont rev above 3000

Hey have you tried disconnecting and re connecting the battery? my mitsi carisma startd doing that so i rang up dealer and aparently they do it when the computer thinks there is something wrong with the engine, so it enters slow mode (or turtle mode or something) so that minimal damage is done while you drive it slowly to yr mechanic. Could be complettly wrong tho. Good luck.

SOURCE: I have a 2004 Mercedes

Hello
A common cause of this problem is a defective fuel pump check valve, hook up a fuel pressure gauge to the fuel rail test port and verify there are no leaks, start the engine and let it run until the fuel pressure is steady, then shut it off the fuel pressure should remain within 5 PSI of the running reading, if not then the fuel pumps built in check valve is defective. The reason this causes hard starting is the fuel drains out of the line due to the defective check valve, when you start you get air to the injectors for a second, this causes rough running and a stall in some cases, 2nd restart in most cases is ok. Do the leak down test and let me know the test results.

Mercedes Benz 2002 - C240 - wont start.


Most parts stores will have a fuel pressure tester available. This is the best place to start, as presence of fuel at schrader valve does not tell you if pressure is correct. Hate to say it, but without proper test equipment you will have bad luck trying to troubleshoot newer cars. For spark, use a timing light, or a cheap inductive spark checker pen. I got my last one for less than $5.

Fuel problems


First start with the basics check fuses relating to fuel and or injectors make sure there is voltage next look into your crank sensor usually if it fails the computer doesn't know you are trying to start the vehicle because the signal the sensor is supposed to give out to the computer is not there due to a faulty sensor once the computer senses the signal from the crank sensor then the computer will send a command to the injectors to start pulsating gas let me know how this turns out for you.

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
