truck will not start or try to turn over

No work done except routine oil change a while ago. Right, no spark.

Best GUESS , without scanner or testing for no-spark (but engine does turn-over/spin), would be crank sensor first , then cam sensor. BOTH are guesses but in this case , checking parts prices on-line and ASSUMING that they are not to difficult to replace(haven't checked that) it may be less expensive than a tow-truck.- - -5cyl. 3.7L engine? I've not had my eyes on one of them yet , so I have no idea what you're getting into! Good luck.
