Re: HARD TO START
Read the codes with an OBDII code reader. they are available at most part stores..........note: some parts stores will read your codes for free if you can get your vehicle there. once we know the reason for the check engine light we'll be able to go from there Thanks!

fuel filter, air filter, spark plugs, pcv, plug wires this is where you will need to start unless there is a specific engine code in the computer that says differently is the check engine light on if so go to your local autozone and have them do a free diagnostic reading take down codes and then i will be able to answer more specifically
The first thing you need to do is have the computer scanned for trouble codes to narrow down the possible causes. But that would require a code reader or scanner. Have you checked fuel pressure with a gauge ? Are you getting spark to the plugs ? Because of the moan from the pump, there's a good chance the pump has failed.
you are on the right track, start with replacing plug wires, then the plugs. first thing i would check. but when you replace one replace them all so you will not have to change a different one every few months. after checking these please let me know what happened, if more trouble shooting is needed i will help you. please let me know if you got covered or if i need to put a little more my brain power to help your horse power.
As you have probably figured out by now, you will have to treat it as a no start and troubleshoot it when it fails to start. Until you figure out if you are loosing spark or fuel to the injectors when the engine dies you have no direction to go in.
I would first check condition of ignition system, wires, plugs etc, as well as have a fuel pressure test done, or at very least change fuel filter. Old plug wires and plugs tend to break down when under load especially, and a plugged fuel filter can restrict necessary flow of extra fuel for load condition as well. Certainly other things may come in to play here, but that is a good place to start.
To be honest, it could be many things. Simple first, check your air filter and fuel filter. They may be clogged. It could need a tune-up. This is spark plugs/coils, wires, distributor cap. If you have a check engine light on, get it scanned for codes. If not, you will have to try the elimination process. If it has been 70,000+ miles on the plugs and wires, change them. Your starter solenoid may be going bad. It could be fuel injectors leaking. The only way to know 100% is by testing everything and visually inspecting the engine. If you have anymore questions, ask us. We are here to help in anyway. Thanks for choosing FixYa.
What motor is in the 04 Cavalier? If it’s the Eco Tech 4, you need to remove the black cover on top of the engine to access the plugs. Once you remove this cover you will see the coils and the wires for the plug are attached to this cover. Gently remove the plug wires and disconnect the electrical connector from the coils. Set this assembly aside. Using an extension and the correct size spark plug socket. Remove the plugs. With the new plugs check and verify the gap is correct prior to installing the new plugs. One the correct cap has been set, install the new plugs. It is recommend to use a piece of vacuum hose to start the threads on the plugs as to not cross thread the new plugs. One the plugs threads are started use your wrench to tighten the plugs. Do not over tighten as you can strip out the threads. Then reinstall the wires and connect up the coils, reinstall the cover and start the engine. Make sure there is no check engine light and the motor is running correctly.
