Next time you try to start it, turn the key to RUN (not start)for 2-secs. Then turn to OFF. Repeat 3 times. Then try starting. If it fires right up, that's a sign of a leaking check valve in the fuel pump. Turning the key to RUN 3 times triggers the fuel pump to go into "prime" mode to rebuild fuel rail pressure. When fuel pressure is back up to spec, it fires right up.
fuel and fire, charge the battery, turn on ignition and listen for the fuel pump to pressurize the fuel lines. If you ran out of gas you may have fried the fuel pump.
Is the check engine light on when the engine is running ? Someone will need to check for spark on all cylinders and fuel pressure. You might try spraying carb cleaner or starting fluid into the throttle body to boost fuel supply and see if it helps. If it does that would tell you its a fuel problem.
black smoke is flooding( uncontrolled injector operation
run the fault codes to determine the problem area ( ECM , fuel pressure , faulty injector control, MAF/VAF sensors or failed heated oxygen sensors
Hi Shansa,
I would suggest you take the vehicle for a diagnostic scan. That will determine and pin point the problem. I would think that if the vehicle is fitted with the constant injection type of system, the problem could be flooding. If that is the case it will be better for a new fuel distributor to be fitted. If someone has tried to adjust the unit, it needs to be taken to a technician to reset the delivery valve setting, if not, its probably showing signs of wear. The symptoms you describe are common to flooding and what would happen if the fuel is wetting the plugs and stopping ignition. The time elapse you relate would give enough time for the fuel to evaporate and then allow the engine to start. Regards Johngee10
Take your car to a garage and get it serviced and tuned. if you have already done so, get a compression test done on your motor to find out how wornout your engine is.
