I would first check the fuel pressure. It could be leaking residual fuel pressure. The way to test this is to connect a gauge to the test port(probably schrader valve on fuel rail) and turn ignition on(engine off) and this will operate the fuel pump a few seconds. Observe the max pressure on the gauge. Depending on the type of fuel system it has it should be:
the pressure should then hold steady after it reaches max pressure. (Residual pressure). If it does not hold your fuel pump check valve (at end of return line), fuel pressure regulator, fuel lines or fuel injector may be leaking. This could cause a hard start or no start.
At regular parts stores these gauges are around $40. But to me they are priceless in diagnosing.
