Cranks, but wont start. replaced battery, fuel pump and ignition coil pack. What else could it be?
It could be bad plugs, plug wires, a bad ground will do this as well. Check to see if it has the three main things.
Spark
Air
Fuel
Anther common problem is the crank shaft speed sensor. It will cause it to not spark and not start.

I agree with Joe check for spark, air, fuel and also compression. The crank sensor is also a great suggestion. For spark you can check or replace the igniter sends the signal to the coil. For air, clogged air filter which unlikely or more possible a gasket leak in the intake manifold or throttle body. For fuel, clogged fuel filter, faulty pressure regulator, leaking injectors and or o rings. Compression, bad head gasket, cracked engine block, leaking piston rings. It could be a valve problem, these are just some ideas as what to look for.
In your case I suspect an electrical problem, a short circuit. I would like to find out more about the electrical side of it. Do you constantly have to charge the battery? Does it get drained over night? When the lights were acting crazy was the blinker switch on or other light switch on? It sounds like you have an electrical problem some where in the steering column.

We checked the timing system and it was fine. For a while, the blinkers would randomly turn on when we weren't using the car. Eventually, they went out and we replaced the fuse and than then the lights on the dash would randomly go on and off. About a month ago, the car would randomly crank and not start but if you waited a couple of minutes it would start. Finally it just stopped starting. The car cranks but wont start. My parents had the same problem and it was the ignition switch, but My husband has friends who are mechanics and they said it couldn't be that so my husband wont check that.
Check the timing system.

My ford Taurus would not crank. It did it yesterday and then after a few minutes it started. Auto Zone tested the battery and the alternator and it was fine. Today when I got back in it, it cranked this morning but when I went to get back in it, it did not crank
new coil,i sprayed starter fluid in breather,it acted like it wanted to start but cranked over but would not start
