cranking fine then nothing

Do the headlights come on? If not or if dim, check the battery cables at each end, where they connect
to the battery, to ground and at the solenoid. Check the fusible link if you still have one. If the
headlights work, it's likely the 10 amp fuse marked ACC second from the bottom left side of fuse block.

Clean the terminals real good.

Happens to me all the time!

Make sure that you have a real good clean ground to your block/frame/body, and that all your connections to your solenoid are good, as well as you battery terminals as mentioned above. If manual transmission, can you pop start it by pushing it?
