I believe it has a fuel pump reset button but I cant locate it. If this is not the case what else could it be?

It does not have a reset button. Will it run on starting fluid?

Truck will not start with starting fluid. Is it possible my alarm has disabled the fuel pump? I have not used the keyless entry remote because ive misplaced it. If this is the case can I disable the alarm?

If it was an alrm problem your truck would start and then stall 2 seconds later and run on starting fluid, so a security problem is not the issue. Have you checked the basics like spark. Check spark at the spark plug, if no spark at the plug, remove coil wire from coil tower and see if you have spark there, if you do than your problem is the coil wire and or the distributor cap and rotor.
