My check engine light would come on and turn off. I had it checked and they told me to start with checking the fuel cap. Finally, I filled up my gas and drove 7 miles and parked. Tried start the car did not start. Check fusses are ok. Sounded like it was about to start but it didnt

Lets do below for a start to determine if its fuel or spark related issue and get back with some results

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, cap and rotor, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
