Answers :

Check your fuel pressure to ensure proper pressure to the block, also did you replace the fuel filter.

\015\012
\015\012AIR-make sure you have a clean air filter and your MAF (mass air flow sensor is plugged in) if you pulled your breather to innspect anything, there is a possibility that it came unplugged or you unpluged it and forgot to hook it back up, a car wont start without it being plugged in if equiped
\015\012
\015\012SPARK-Make sure your car has juice to the plugs, if the plug doesnt fire the car wont run, if you have to pull each plug and ground them to the engine block to see if they arch. If not trace the problem down (if you changed the fuel pump you have some mechanical skill and should be able to troubleshoot a spark issue)

\015\012FUEL-Check for proper pressure, dirty fuel filter(s) and if your system has a return line, make sure your hoses didnt get crossed cause this will damage the engine and regulator.
