Question about 1994 Mercedes-Benz E-Class

1 Answer

The car is not starting, the engine is turning weakly

The car stopped on the way in a traffic jam. After the driver tried to start the car, it was not starting. On continuous trials, the battery went down. A new battery was used, the cable that went from the battery to the kick starter started getting hot. At that, the kick starter was repaired. It was turning the engine but not fast.
There were little spark in the plugs when tested. The feul pump was tested and it's okay. The brain box was tested ans it was okay. The injector was tested and it was okay. The coil is okay.
What could be the problem??

I Is the engine wire harness original? or has it already been replaced?
if its original, this may sound crazy unless you already know that MB has a big problem with the wires under the hood.
But your car may need a new engine wire harness.
They start to crumble leaving the wires bare in places to short together and cause all kinds of crazy things.
Your car is at the perfct age to start experiancing this problem.
Unfortunetly the best way to cure this is to replace the harness.
A harness costs about $900 new, plus labor.
To check the harness, I unwrap the wires in several places on top of the engine by the injectors, and for the ignition coils and a few other places, I then bend the wires around a little, and look for cracking or crumbling. If you see ANY cracks in the insulation, that is not good .
To replace the harness is acually easier than it looks. it takes one to two hours, even less if you done one before.
There is a high percentage of the MB that I have seen, have this harness problem..

Good luck, and I hope this info helps

How to save fuel and make your vehicle last longer, too


Improving fuel economy is easy - just take it easy. It willmake your vehicle last longer, too. Here are some specific tips on how to savemoney on both fuel and repairs.
  • Keep your tires inflated at the correct pressure. Under-inflation causes tire wear and wastes fuel.
  • Do not carry unneeded weight in your vehicle. Excess weight puts a heavier load on the engine, causing greater fuel consumption.
  • Avoid lengthy warm-up idling. Once the engine is running smoothly, begin driving - but gently. Remember, however, that on cold winder days this may take a little longer.
  • Keep automatic transmission selector lever into "D" when engine breaking is not required. Driver with the selector lever in "4" will reduce the fuel economy. (This is referring to vehicles with Automatic drive)
  • Accelerate slowly and smoothly. Avoid jackrabbit starts. Get into the high gear as quickly as possible.
  • Avoid long engine idling. If your have a long wait and you are not in traffic, it is better to turn off the engine and start again later.
  • Avoid engine lugging or over-reversing. Use a gear position suitable for the road on which you are traveling.
  • Avoid continuous speeding up and slowing down. Stop-and-go driving wastes fuel.
  • Avoid unnecessary stopping and braking. Maintain a steady pace. Try to time the traffic signals so you only need to stop as little as possible or take advantage of through streets to avoid traffic lights. Keep a proper distance from other vehicle to avoid sudden breaking. This will also reduce wear on your breaks.
  • Avoid heaving traffic or traffic jams whenever possible.
  • Do not rest your foot on the clutch or break pedal. This causes premature wear, overheating and poor fuel economy.
  • Maintain a moderate speed on high ways. The faster you drive, the greater the fuel consumption. By reducing your speed, you will cut down on fuel consumption.
  • Keep the front wheels in proper alignment. Avoid hitting the curb and slow on rough roads. Improper alignment not only causes faster tire wear, but also puts an extra load on the engine, which, in turn, wastes fuel.
  • Keep the bottom of your vehicle free from mud, etc. This not only lessens weight but also helps prevent corrosion.
  • Keep your vehicle tuned-up and in top shape. A dirty air cleaner, carburetor out of adjustment, improper valve clearance, dirty plugs, dirty oil and grease, breaks not adjusted, etc. all lower engine performance and contribute to poor fuel economy. For longer life of all parts and lower operating costs, keep all maintenance work on schedule, and if you often drive under severe conditions, see that your vehicle receives more frequent maintenance.
Good luck.

Attempted to jump start my 2001 3.5 rl acura and


10gage cables?
does engine turn by hand? if not,its seized.
the starter can pull 500 amps. (if cold) its called a series wound motor.
and the harder the engine turns, the more amps and HP from this
electric motor. id turn it by hand, if you can turn the engine crank
by hand than try real jumper cable (they cost more) and if they
fail the starter is jammed, or is shorted.
starters can be dead, shorted, open, weak, or jammed.
if the engine spins, take the starter to any autostore, they test it for free.

My Hyundai Matrix car is not starting. When I turn the key to start the car it tumbles but won't turn on. I know that it is not the battery because we took the same battery and installed it into


got same symptoms with my hyundai matrix. Engine just stalled when car is not in motion (i.e traffic light, traffic jam), plus a cylinder misfire. I went online for some search (this site included). Then went for OBDII diagnostic.

Its the Crank Position Sensor/Crank Sensor/ CKP Sensor or whatever it is called. Had that replaced, and she's been back to well behaved since.

What can make my car do this? Cause I need to go to the mechanic but I don't want to get cheated cause I am a girl who doesnt know anything about cars. I was going over the New Orleans bridge last night,...


There is an electronic problem, that is why the engine light comes on and goes in to limp mode.
Your local dealership (Dodge) could pin point the problem with a diagnostic check, and should not cost you anything.

Car just stops running while driving in traffic,will start up aft


Could be a lot of things. Most common would be the fuel filter plugged or weak fuel pump. It could be a faulty air control valve, or idle control system, emissions or engine control system components faulty. Faulty or incorrectly gapped spark plugs or bad plug wires. Vacuum leak at the intake manifold or broken, cracked or loose vacuum hoses. It's sort of hit and miss, unless you take it somewhere where they can check it out with a scanner, but if you don't have an engine light coming on, that won't help much either. Good luck!

Problems when starts..


Turn your key on for 10 seconds but do not start the engine. That will give the fuel pump time to built pressure. After the 10 seconds try starting the engine. If it starts right away you may have a weak pump or dirty filter.
