Kingdrogba before you go too far the most common no start issues are bad grounds/battery problems and RCM ( Relay Control Module ). I hope you have read the post on Mystery No Start issues in the TSB and How to section of the forum. If you haven't, you really need to start here: Mystry No Start there are a few bad solder joints and with time the contacts on the relays go bad.

Also you should be certain all the connectors in the large block box just inward from your battery are snug and tight. Inside that box is the RCM, PCM and the BCM. Others have corrected the no start issue by simply wiggling and pushing in on the the connectors to those boards.
