The mere presence of fuel and a spark are not enough to guarantee combustion on their own. The engine needs the fuel to be atomised in the correct stoichiometric ratio with air, and the ignition spark needs to be timed correctly to force the piston down.
What happens if you spark the engine at the wrong time?
But these things generally have to occur at a specific time. If you spark on the exhaust stroke then nothing will happen. Assuming it is a fuel injected engine, if the fuel is injected at the wrong time it will cause manifold wetting, and potentially icing, but also a poor running engine or a no start condition.
What causes the fuel pump to not start?
The fuel pump is running and delivering normal pressure to the engine But, with all that working your engine still will not start.

What causes no power to fuel pump, no spark?
That also cause the no fuel or spark condition, because the engine gets its timing from the signal. The wiring often gets cooked by the exhaust. It’s located down on the bellhousing on the drivers side.
Tried to start it with the pump running and it wouldn’t start. Then realized that the multi function unit probably needed to be plugged in for it to run. Plugged that back in and jumped the fuel pump from the inertia switch and it still wouldn’t start. Then checked the spark. No spark. Checked all the fuses under the hood, all ok.
Why is my car engine not getting spark?
There are lots of reasons why you might not be getting spark. If it’s an old car, it might be your points. If it’s an old motorcycle, it could be your ignitor. You could also have a bad distributor, a bad coil pack, or even bad crankshaft and camshaft position sensors.

A more expensive form of engine stoppage is a ‘blow up’, or mechanical failure. This usually only happens after a total loss of oil pressure or after extreme overheating, both of which the car’s instruments or warning lights will warn you of in time to save the engine by switching it off.
What happens when the engine stops dead in a car?
If the engine stops dead, the chances are that the fuse (if one is fitted) protecting the ignition coil has blown. If the ignition light will not come on but most of the electrics work this is almost certainly the problem.
What happens when you shut down an engine?
Water can work its way into the cylinders several ways. With the engine shut down, wave action can force water into the exhaust discharge and up the hose until it fills the muffler. Once that happens the hose will begin to fill and the water level will start to rise on the exhaust hose leading from the engine to the muffler.

Why does my car not start without starting fluid?
This was the crank position sensor. Now the car will not start without starting fluid. When starting fluid is used, the car will start and then run fine. Once you shut it off then try to start it, same thing. The fuel pump turns on when key is in on position. Holding pedal down to try and clear flood does nothing.
