Answer
Hello Enis,
First, make sure there is spark to the plug wires.
Next, see if you can hear the fuel pump in the fuel tank running. It should run for two seconds when the key is turned to run, then for as long as the engine is cranking, or running.

If the pump runs, then I would check the fuel pressure.
Throttle body injection needs 13 PSI, and CPFI injection needs more...like about 45 PSI, but I'm not sure exactly.
