Yes. You can rent or borrow a fuel pump tester from somewhere like Advanced or Autozone. It will come with directions on how to use it.

Checking spark is a matter of twisting and pulling the spark plug boot off the plug and inserting a Phillips screwdriver into the boot all the way. Hold the handle over the screwdriver over a good source of ground on the engine and have someone try and start it. You should see AND hear the spark. Nice bright blueish white color and audible.
