The other mech told me to check for ground wires under my car and I looked and could not see any that were broke.
I just cant see that stoping me from at least getting it to start for at least a sec or two by spraying fuel down the intake.
So I have spark and can hear the fuel pump and I know that dont mean its good so I sprayed fuel in the intake and it still dont want to even try to run at all.
THANKS KEN

For an engine to run, you need three things to happen inside the engine, compression, fuel and ignition, without any one of these components the engine will not run. Follow the repair guide below:

Engine Configuration with Camshaft Operation

Compression - Engine compression caused by crankshaft rotation and a piston moving up and down inside the engine block. If the timing belt or timing chain fails it will cause the camshaft to become out of correlation with the crankshaft or allow the camshaft to stop rotating. Either of these conditions will cause the engine to lose compression and sometimes cause internal engine damage.

Fuel Delivery System - The fuel system includes: fuel pump, fuel injectors, pressure regulator, fuel filter and pressure lines. This system is used to supply fuel under pressure to the fuel injection system, the lack of fuel pressure or volume will cause the fuel delivery system to fail and the engine to stall or not start.

Ignition Spark Delivery System - The ignition system components include: spark plugs, spark plug wires, crankshaft angle sensor, camshaft angle sensor, ignition coil, ignition module, knock sensor and ECM (engine control module). The engine relies on the ignition spark to be delivered to the combustion camber at the correct time. If the ignition spark stops or is delivered at the wrong time the engine will not run or run poorly
