Question about 1996 Mercedes-Benz C-Class
I took it to mna shop and they fried my wireing harness i have ffixed all the melted wireing in doing so i nhad to dis connect every thing i tried to start it but it didnt fire
Normally just disconnecting the wiring won't require the modules to need to be programmed, its more than likely the shorting that occurred when the wiring harness melted that has damaged one or more of them, I would advise sending all three modules away to a automotive electronic repair shop for testing and repair.

You may also have issues with your air flow meter.Generaly though this symptom is usualy a fuel pressure problem.This test may or may not work depending on wether the fuel rail is the problem or the pump.Squeeze the fuel return line at the back of the fuel rail and if engine improves the fuel pressure regulator on the fuel rail may be faulty.If no improvement its likely the pump.The best and most accurate test would be to use an inline fuel pressure tester.Can you hear the pump pumping up to pressure when you turn the ignition on?Usualy though the pumps fail but can be heard running but unable to maintain pressure.

The electrics in the Mercedes are notoriously flaky. A failing alternator would cause a low voltage condition that would cause the battery to run down but would not likely damage any of the computer modules. Have you REPLACED the fuses that protect the various fuel and ignition modules? Not just visually inspected, but REPLACED them? When I ran my Mercedes 123 series cars, I replaced all the fuses on Day One, regardless of how good they looked. Bosch fuses are known to corrode and cause intermittent problems similar to yours. If a fuse is overheating or the contacts are not good, a few minutes of driving could cause a problem that imitates expensive module failure. It happened with my Mercedes and my Volvos that used Bosch fuses.

there are relays under the screwed down portion of that box. One or 2 strip fuses are outside of the box for the Aux fans and blower motor which it says on the fuse card.
