The firing order for an '83 Mercedes-Benz V-8 is 1-5-4-8-6-3-7-2. And, here's some more information. If you are wondering which physical plug corresponds to the number 1, look at the engine's banks (it's a V-8, so there will be two banks for four cylinders). As you stand there -- you should be at the front looking toward the windshield -- the left-hand bank of cylinders are 1 to 4 (1,2,3,4) and the right-hand bank is 5 to 8 (5,6,7,8). I hope this helps.
when you say not firing have you removed the plug and checked for spark across the plug points. If you haven't done that then do so as misfiring can also be from faulty injector( blocked tip or faulty electronics)
Generally speaking it can be a spark, fuel, or compression-vac leak problem. So the spark plug, coil, fuel injector, vac leak, or internal engine problem would do it.
P0300 Random Misfire Detected P0301 Cylinder 1 Misfire Detected P0302 Cylinder 2 Misfire Detected P0303 Cylinder 3 Misfire Detected according to this fault codes first mark ignition coils 3 ---------------- 6 2 ---------------- 5 1 ---------------- 4 RB-------------LB this right banks and left bank, please remove Ignition coils with lids and spark plugs from right bank and swap with left bank, if fault code change as P 0304 Cylinder 4 Misfire Detected P 0305 Cylinder 5 Misfire Detected P 0306 Cylinder 6 Misfire Detected You can Identify it's a faulty ignition system then next swap ignition lids from ignition coils be careful each coils have two lids one short and other long bit deference and when you remove and fix it to the car keep in mind correct order because each coil two different fire for two spark plugs don't mix up, if you mix it can create the fault code.if you detect any fault ignition coils or spark plugs or lids replace that and also whether god or bad recommend to replace spark plugs, find the right that's most important thing, if this way couldn't found the any ignition fault next step is check fuel presser, when the engine running fuel presser must be around 4.5 bar without engine running must be 4 to 6 bar if the fuel presser too low need to check two different things one is fuel pump other is fuel injectors, in this case you can swap injectors from right bank to left bank and find is the injectors leaking, if not leaking faulty fuel pump.is this information helped you? if yes please leave a comment,
most older mercedes benz firing orders are written on valve cover. I beleive it will tell you on one of the rear intake manifold runners. the way a benz engine cylinders are marked they read-1 2 3 4 on the l(passanger side) and 5 6 7 8 on the r(drivers side) unstead of 1 3 5 7 and 2 4 6 8. maybe this will help you good luck getting the plug sires back into the plastic troughs.
