A few things! Did this just start happening or has it been a gradual development (the motor would start stalling, not wanting to go under heavy acceleration)? First thing you want to do is check the fuse. Maybe the fuse went. You can locate the fuse in your Merc's owners guide. It probably isn't in your fuse under the steering wheel -- Mine is the engine compartment power distribution fuse box and it is a square off-white color. If that is good, check the relay in the interior fuse box right behind the kick-panel. It is the one all the way to the back -- Relay one. Check that relay. If both those pass your inspection, now you want to see if the fuel pump is working. Turn the ignition to the 'on' position but do not crank it so the engine starts -- Just allow all your dash gauges to turn on. Make sure the door is open and keep your head out the door to listen to the rear of the car where the fuel tank is located. If you hear a high pitched electric noise that turns off after about 3-4 seconds, that is good! It means your fuel pump is working fine. It can be is an old fuel filter that is clogged. That is a relatively cheap and easy thing to do. It could also be a clogged or broken line. One more thing... Did it happen after the car stopped rapidly or accelerated rapidly? Ford made a feature that would turn the fuel pump off if the car detected rapid acceleration or deceleration (So fuel wouldn't reach the engine and find ignition in case of a crash). Luckily there is a reset button if this is the case located in the trunk. Luckily, the fuel system isn't terribly expensive to work on or fix.
