I am also haveing this problem... only it is really getting bad, i can go for 5 or more minutes trying to start and only getting a click sound and no turn over then it will almost start and takes a couple more tries to fully start and run... thought it was low fuel pressure cause was only happening when the tank was below 1/4 but not it does it when tank it full also... i have the ability to change the starter but don't know if that is really the problem and don't have the money to just throw away at a problem till i fix it... already learned that from the check engine light with a code for the front right O2 sensor... ended up buying 2 different sets of front O2 sensors before i got the dang thing fixed... if someone could describe what to look for on the starter relay to figure out if that is good or bad and where else to look before i pull off the dang intake manifold for nothing i would appreciate it... i have acess to a multimeter and all the regular tools i would need for doing work on this truck as i work in the army fixing helicopters so i think i can figure this out with a bit of help...
