Black smoke - over fuelling. Commonly caused by leaking injectors, dead oxygen sensor, faulty coolant temperature sensor, faulty MAF.

Scan and post the codes

How to Diagnose Vehicle Fuel Problems

If the engine turns over but doesn’t start running, the first question you need to answer is whether your fuel tank is empty. Even if your fuel gauge says that you still have some fuel, the gauge may be on the blink. When did you last fill the tank?

Sometimes the problem is too much fuel. If you open the hood and find that everything is covered with gasoline, don’t try to start the engine! Gasoline is too flammable to monkey around with. Just hoist that white flag and get help.

If you’re not out of fuel and your vehicle lost power before it died, fuel is probably not getting to the engine. Here are some additional reasons that specific types of vehicles may not be getting enough fuel.

Gasoline- and diesel-powered vehicles: If you have a modern vehicle with a multiport or sequential fuel injection system, either the fuel pump isn’t pumping fuel or the ECU isn't triggering the fuel injectors. In either case, a professional will have to troubleshoot it.

Ethanol, methanol, and flex-fuel vehicles: The potential problems are the same whether the vehicle is running on pure gasoline or on gasoline mixed with alcohol: Either you’re out of fuel or the fuel pump or fuel injectors aren’t working properly. In any case, there isn’t much you can do but call for help and be patient until it arrives.

Electric vehicles: If an electric vehicle suddenly stops running, the battery that drives it (the big one, not the little guy under the hood) has run out of juice. Either you’ve driven too long without recharging it or the system is malfunctioning. Dashboard malfunction indicator lights should alert you to this problem before the vehicle stops completely.

To add to what Autobays said, I am certain your knock sensor is also out. Do a scan and report back. Your fix lies in the scan result.

PALLY, get a good electrician, he wil rectify it for u.....major culprits are 02 sensor and MAF sensor. In my case I serviced injectors, changed plugs, plus plug wire all to no avail until my Electician traced d airflow and fixed it well. I wish u luck bro, keep us posted
