The Symptoms tell me it is a head gasket. A leaky or bad head gasket would cause all of the problems that you mentioned.

Burning water causes White Smoke, Burning Oil causes Black Smoke. The oil and water are mixing with the gas in the cylinders and causing it to run bad. Pull out the dipstick and look at the oil on it. Does it look like good oil? Or does it look watery and or foamy or grey colored. Open up the radiator and look inside, do you see oil?

This seems almost text book to me... I would have someone local to you to have a look at it to be sure.

Hi ddansvob-

Most of the codes for Mercedes C320's can be cleared (at least temporarily) by disconnecting the negative terminal of the battery and leaving it disconnected for at least 1 minute. I would give it several minutes just to be sure.

There is also a reset procedure that you can use that involves disconnecting the battery, turning the ignition to position 1 several times and then reconnecting the battery. That procedure can be found with a google search.

Possibly the easiest way though is to visit an Autozone or other similar store that has an OBDII scanner that they will use for free on your car, and have them reset the codes. If there is an actual issue with a sensor, etc. though, the code will come back up after the car has been started a time or two. If that is the case, you are going to have to troubleshoot the actual cause of the code, involving finding a Mercedes shop that will help you with identifying what sensor(s) are causing that code to show up.

If your mechanic used non-OEM parts/battery, that is very likely to be the source of your problem. Assuming that they didn't do that (which would be unusual for any mechanic to do), you are likely looking at replacing a voltage sensor or part of the voltage regulating/distribution system. If you get to that, you are REALLY going to need an experienced Mercedes mechanic.

Good luck!

How long after the Injection pump repair did this start happening? If not long ago, I'd go back to the repair man or ?Dealer?. Was the overhaul Manufacture recall? It's highly unusual for injection pump failure on a fairly recent Auto.

There is a possibility that the old motor was not burning properly and you have carbon build up on the O2 sensers. A poorly functioning O2 senser will not allow the Fuel/Air mixture to work as you give it gas under load. You could have multiple O2 sensers too.

1991 geo storm gsi,Was going down the road fine and all of a sudden It cut off and cannot restart it what could be the possible problem or cuses.

same answer for all cars made 1920 to now.
never restarted ,ever ? gee , a little hint...?
1: lost engine compression hot, (gee forgot to do the 60k serviice/)
2: lost spark , yes, check spark at all 4 cyl. if bad check coil spark.
3: lost fuel or too much fuel called flooding.

one removes a spark plug, it drips of fuel , say all 4.
crank motor at WOT, wide open throttle to clear flooding.
if the spark is good and the spark tips are dry, then try test fuel
if car starts and dies. then you lost injection.

easy huh> with the above you know exactly why it fails.
compression bad

1991 i think is TBI single injection engine, i can look it up but
no i wont. we need to do the tests first to get there.

My car always jeck after running for more than 45 minutes. when it rest and get cooled, it runs perfectly but when it becomes a little bit hotter than it starts jecking sometimes the engines goes off and...

You will need to check on the two major areas of suspicion.
1. Check the fuel pump as on heat some pumps can bring in low pressure and irregular injections.
try and calibrate the pump to confirm with heat simulated .
2. Check the HT spark on the plugs, check the spark when the engine is hot , check the HT coils and the plugs and most important the ignition system.
The poor performance of the fuel and spark setting- timing -can reduce performance and thus increase the fuel consumption.

I have a audi a3 2000 w reg 1.9tdi the problem is its hard to start in the morning when i get it started it runs perfect then if i try to start it hot the problem is the same takes a few goes to fire up ....

i think the problem is the injector pump ,this isnt common rail as yet for this age vehicle and when its starting its not throwing the auto start mechanism into play which makes it over inject fuel ,remember the old transit with the inline injector pump,lift bonnet pull throttle and push button in ,then it would go first time .well its the smae thing buts done electricaly ,only solution is to put car into a bosch injection specialist and have the pump overhauled ,lots of cash though,or use a can of brake and clutch cleaner --- and thin pipe into teh air intake and spray some of the cleaner into the air intake ,brake and clutch isnt as harsh as easy start andf their is a nozzle on the can so the pipe pushes onto that ,just like the old perkins diesels in the transits in the 60s only it was a plunger on the dash in them days .

2000 GMC Jimmy 4.3L CSEFI won't crank. Fuel pressure is 50psi and should be between 55 to 60psi. Fuel filter 1yr old and fuel pump is probably stock & needs replaced but never had problem before...

Check your starter and check your connections to make sure they are clean and tight. The low fuel pressure won't cause a no crank. Too low could cause a no start but not a no crank. I've had starters be bad right out of the box. But if that starter motor isn't turning either the starter motor is bad or the solenoid attached or the wiring to it is at fault.

My car will start just fine, and I'll drive to the store and I'll try starting my car for about 5 minutes and finally it will start.

what you have is fuel injection won't start hot. usually this means that your injector system is not sealing off fuel when you shut car off. after you shut it off the fuel continues to flow for a little while, fuel pump is shut off but there is still pressure in system and it flows around bad seals. if you let it sit for several hours the fuel evaporates out of the cylinders or runs down into the oil pan. but if you try to start it hot it is the same as trying to start a flooded engine, pretty much that's what it is. believe it or not, the fastest way to clear a flood in fuel injected cars is to hold the accelerator pedal to the floor while you crank the starter. the long term fix is that your fuel injection system needs overhauled. hope that helps
