    Most likely the crank sensor or wire leading to it. The salt used during the winter here in New England, corroded my wire leading to the crank sensor and it wouldn't start. My brother in law is a mechanic and found it right away. It's located under the truck up near the transmission, but not exactlly sure where. Ask a Nissan mechanic to show you on one. Easy fix if that is the problem.

    Check the "power module" in the main fuse block-passenger fender, behind battery. Right next to PCM, pull off cover. White module with fuses & relays, many plug-ins, 2-easy release tabs-pull up a little to see relays. Check all plug-ins while someone cranks it. Try tapping on it with large screw driver or small hammer while some cranks engine. Then notice it has 2-rows of small black relays-top row has 5-relays, bottom row has 4-relays. Pull relay out of far right hand side-move all other relays one space to the right, with the 1st relay pulled installed all the way to the left-do this with both rows. This has worked with an 06 Frontier, and a 05 Titan with the same symptoms as yours. I discoverd this only after much other diagnostic work including replacing crank and cam sensors-which was not the problem. I believe if the power module has to be replaced, it is pretty easy, but think requires dealer programming ?

    Most likely your IPDM has failed and needs replaced.
