Your car needs air fuel and spark to fire. If the fuel pump is priming, that's not the problem. Check your ignition fuse.. it might be blown. Did you try giving it a little throttle while it was turning over? Then check spark plugs.. no spark = no run. Worn out plugs = barely starts, runs like ****.

Not necessarily true. Bad regulator (or broken vacuum line to the regulator) would allow the pump to prime but not let the fuel past the regulator.

you dont need two people. get an inline spark tester. it plugs into a wire and plugs onto the plug, or cap. then you just crank, and it lights up if there is spark

If it has spark then put a fuel pressure gauge on the rail and check pressure if there's a blockage somewhere pressure will be slow to build if at all even though you hear the pump run doesn't mean all is well with the fuel system check the regulator... pull the vaccum line make sure no leaks are there and check for injector pulse with a noid light
