The firing order for a Chevy s10 depends on which engine you have. 1.9L engine the firing order is: 1-3-4-2 . Distributor rotates counterclockwise. 2.0L engine the firing order is: 1-3-4-2 . Distributor rotates clockwise. 2.5L engine the firing order is: 1-3-4-2 . Distributor rotates clockwise. 2.8L engine the firing order is: 1-2-3-4-5-6 .

SOURCE: mercedes 300te radio code

You need to pull the radio from the dash and get the serial number of the radio which is on a label at the back.

Mercedes do not make stereos themselves but use various different manufacturers for their radios.

Once you have all the information from the label post it up and we can see if your radio is one that can be decoded by serial.

SOURCE: I have 250000 miles on

If you have replaced the timing chain please disregard my answer, I'm risking my rating because I want to help you for free.
If the timing chain has not been changed that the problem might be an overstretched timing chain.

As timing chain accumulate mileage, chain stretch, sprockets wear out, and set the valves off timing. Most chains go up to 100000 miles or more, but not always. As a rule when there is more than about half inch of play between the gears on a V6 or V8, it is the time for a new timing chain and sprockets.
It is not unusual for a timing chain to accumulate 200000miles, but I remember a car, with broken timing chain, with only 160000miles on it, the valves were bent and a hole was put on the piston.

Signs of worn out timing chains are:
Rough idle.
Sluggish performance and poor economy.
Sudden engine performance change including the inability to start the engine.
Intermittent backfire through the intake manifold.
Inconsistent ignition timing or a clattering noise coming from the front of the engine.
It is a good idea to replace the water pump (coolant pump), and the thermostat while replacing the timing chain.
The cost of the replace of timing chain is at least +$1300, but if is to bad, we pull out engine and replace both guides. In this case might cost more.
Please do not be mad with me. I'm a certified dealer, and I'm trying to give you the necessary information to help you to deal with the problem.

Check the crankshaft sensor again. It may have come loose, or the electrical connection may be loose. If there was physical damage to the old crankshaft sensor, the new one may have become damaged also. If everything is ok with the new sensor, scan the computer for fresh trouble codes.

Can be that the oil pressure sensor has a loose connection at the terminal or that the pressure switch is faulty.
You will have to check this out, replace if faulty.
Hope the oil filter was also changed as you have not mentioned.

Car won't start, battery is fine. No indication of any problems, returning from funeral car won't turn. All lights, radio everything else works fine.


May be neutral safety switch, put into neutral and try to start. If that works have switch replaced its on the transmission. Even if it starts that way it wont take long before the car wont turn over in that position.

Could be, but I would check your engine wiring harness as MB was forced by the US to use a biodegradable insulation on the wiring and with heat starts to crack and fall apart. Also check voltage regulator on the alternator and your coil.

1995 Mercedes S 320 won't start. battery is fine


I know on the L.H. (previous fuel injection system) models there was a module called a base module that worked as a big overvoltage relay and powered up all the control units for the engine and drivetrain,they had 4 to 6 10amp. fuses in the top and theywould blow fuses and sometimes fail themselves causing no start conditions. I beleive yours is an H.F.M. system. I used to do roadside and i'm also a mercedes benz tech. The first thing I would try would be to put the car in nuetral and see if it starts. the nuetral safety switches of that era are problomatic. next I would check my brake light fuse in the engine compartment fuse box. That fuse also powers the starter relay-even though it doesn't state that on the fuse schematic. Also to answer your question about a lockout relay-yes there is but they rarely cause a problem. I hope I have been helpful
