I've been having issues with my car starting. I recently bought a new battery, and at the time I was told my old battery was still ok. but i figured I was due and wanted to be safe. I also cleaned off all the corrosion and bought spray to use so i can continue to keep the terminal posts clean. However, i am still having issues. Everything seems to be fine, it just wont turn over. sometimes, after being left alone for awhile, it will start. I am at my wits end. I dont know if it could be the starter, plugs or what? any suggestions would be great. thanks

"Turn Over" - by that you mean engine doesn't crank? Later will? How good are the cable connections at the battery. Clean or not the chintzy bands don't take corrosion well at all and about can't be cleaned up as there isn't much left to them.
Check those out and follow both to check the other ends of battery cables. Weakest one is the best you are going to get,

You need to see if you have power to the small trigger wire of the starter solenoid when it won't start but the key is in the start position. If not there are a few things that can cause that and it gives us a direction to go it. Does moving the shifter a bit make it turn over?

no, moving the shifter has no impact. Im thinking it is the starter, just dont want to replace a part that doesnt need it. seriously debating buying a newer vehicle, but i've had this car for years and generally runs great.

There is a standard series of tests designed to isolate the cause of any "crank, no start" which i will give you. Hondas have a lot of problems with the main relay causing intermittent "no starts".
All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.
Every engine requires spark, fuel and compression to run. That's what we have to look for.
These are the basics that need to be tested and will give us the info required to isolate a cause.
1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.
2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.
3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.
4) If all of these things check good, then you would need to do a complete compression test.
Once you have determined which of these functions has dropped out,
you will know which system is having the problem.
