Test for spark. Remove a cable or plug whichever applies and put in near a ground. If u have spark it will arc it to the ground ...... just make sure u arent touching anything groundish just in case it has a bad coil/ wire the one u choose to test for spark. Personal experience it will tingle quite a bit lol. For fuel use the test port. Use a small object to depress the schrader valve to see if there is fuel in the rail. Once no more fuel comes out turn the key to on w/o starting the car and check to see if u have fuel. Anything else besides those 2 can be timing or a crank or cam sensor gone bad.
