Put new plugs and new wires in 95-96 Ford Aspire and the engine turns over but it still won't start why?

Answer 1

Remember, it takes 3 things to get an engine to start, air, fuel and spark. Air is always there and shouldn't be a problem, so the problem is either lack of fuel or spark or a problem concerning when the fuel and spark is happening. If you turn the ignition switch to the "ON" position and hear the fuel pump running for a few seconds, it is a good bet the fuel pump is working. if you remove one of the spark plug boots from the plug and lay it back on the top of the spark plug loosely and crank the engine, if you are getting spark, you will hear a snapping or cracking sound when the spark plug should fire. (remember that the coil on an electronic ignition auto might put out up to 30,000 to 50,000 volts! don't touch that spark plug wire! it will shock you. don't ask me how I know this is true!). If both of the above are true, it is time to check the timing of the car with an inductive timing light. An inductive timing light connects to the battery and to the first spark plug wire, while cranking the car, point the timing light at the timing gauge located on or around the crank pulley. There is a slot on the crank pulley and an indicator telling if the timing is before top dead center (BTDC) or after (ATDC) zero degrees is top dead center (TDC) if when you crank the car while pointing the timing light at the indicator, if the slot on the crank pulley seems to stand still when the timing light flashed and the slot is within the area of the indicator, the car is close to being in time. If you don't see the slot on the indicator when using the timing light while cranking, the timing belt must be checked to see if it is broken or it has lost a few teeth from the belt.
