T100 Fuel Pump Question

I have a 1995 T100 SR5 that I have been chasing a starting issue.. I have read one way to tell if the issue is with the fuel pump check valve is to turn the key on (without starting) for about 10-15 seconds 3 or 4 times and then try.. Supposedly this cycles the fuel pump to put pressure in the system.. My question is, should you hear the fuel pump cycle when you do this? I tried this today and mine makes no noise at all! Nothing! When I try to start the truck after doing this it still cranks and cranks.. I thought you should be able to hear the pump when doing this??? Thanks for any help!
