I noticed you replace the crankshaft sensor, but not the CAMshaft sensor.
The Ignition module takes the input of both sensors to tell the coil when to energize.
This sensor should come up as an error code when you attach a obd reader.
Even if your light is not on - there may be a code. If it is not your vehicle originally, some people pull the bulb!

hi jasso, I would recommend checking the water pump if you see no flow in the radiator. Make sure when you fill up the cooling system, that you fill it cold, and that the vent screw in the radiator is loose. fill system until fluid comes out the vent screw. tighten the screw, start the car and have someone run at 1500rpm and check for flow.also, make sure that you have your temp setting full hot and blower on middle speed so that you don't trap air in the heater core.

A radiator fan is designed to pull air to pull air through the radiator to help cool it, while blowing the air on back across the engine to try to assist once again at keeping the unit running cool as to not over heat.

like snownbird33 said, first you need to make sure the cooling system is burped. if all the air is'nt removed it will run hot.second make sure your cooling fans are operating, they useually want come on until it reaches around 227 degrees,or the a/c is turned on.third make sure the water pump is'nt leaking if it's a 3.1 liter or 3100 (same engine ) they are bad about the water pump leaking or the blades on the pump are corroded off or propellas are slipping on the shaft.

The check engine light should be on--rent a scanner, read out the codes, and pursue to repairs. The one sensor you didn't mention is the camshaft sensor. It is a hall effect device and depends on a magnet passing to generate triggers. It is combined with the crankshaft sensor and they work in tandem with the CPU to generate firing. Maybe the magnet came off of the camshaft? If you have access to an oscilloscope, you could look for pulses from both sensors where they go into the ignition module--terminal 'G' for the crank, and terminal 'K' for the cam signal.
