Chevy  1500 cranks but won't start

I have a 1998 Chevy 1500 truck and it won't start.  It cranks over good and almost tries to start but then doesn't.  I know that is not much to go on but I'm not mechanically inclined so any help would be appreciated.

If it cranks, but doesn't start, the following are GOOD:
1) Starter motor
2) Battery

What MAY NOT be good: (Things to check)
1)  Not getting gas/ bad gas: Check fuel pump; fuel filter (possible clog); clogged injector
2) Check for spark, ignition wires, electronic ignition unit

Get an OBD code reader and see if any codes are in memory... Didi your "check engine" lite come on?

So not likely battery (otherwise would not crank well).
Could be spark plugs but not likely (tries to start).

So, Fuel Pump, low gas, Carburetor issue, possibly water in the fuel system. It seems most likely a fuel issue.

Any idea where I would check for spark plugs or clogged fuel injector on a 1998 chevy 1500?

There is more than one reason for that light (at least on modern vehicles).  Fuel pump may not be able to pull fuel which also may cause this light.

Fuel injectors would have to be pulled to check. Spark plugs would all have to be suspect, so would all fuel injectors.

You should probably see if you can get the vehicle to a mechanic.
As I said in original post... Get (or borrow) an OBD code reader... It will (most likely) tell you what issues have presented in the past... That's a good place to start the investigation!

When I press down the gas pedal on the truck for about a minute straight and then tried to start it it started. I had to crank it for about 45 seconds before it turned over and started. Before I try it I looked at the battery gauge and it looked Like it was less than a half an hour after it started it went past half quite a bit. Not sure if this has anything to do with it or not. Since I got it started that way is there anyway to know what the problem was?

Cranking for a minute will drain any battery but the battery is likely fine.

I suggest you look at the causes above.
