Right above the Crankshaft pulley.

When you pull the sensor, you need to make sure the engine is at TDC (top dead center).
The new sensor you buy should come with an alignment tool, you need to put the new sensor in the same place as the old one.

Then, reverse procedure.

Unplug the connecter, clean and check the pins.
Disconnect battery, and let sit for 30 minutes.
Re connect both.
The battery should have reset the computer. then drive it and see what happens.

ok, i took neg batt term off and unpluged crank sensor then let it sit for a little over an hour. in the mean time i pulled every fuse and cleaned it with electrical spray. hooked batt up and sensor and the code was gone. i have drivin about 35mi and still no code. now did this just clear the concern or is it possible that the sensor lost its pick up sense under water and now that it was cycled and dry it can pick up the reading again? it still has a misfire only when i initually give it gas? mabey coil? plugs are new?

If you code hasn't come back, then i wouldn't worry about the sensor.
If you still have a misfire, Start with Spark Plugs and Plug Wires.

If you have a confirmed misfire, i'd start with the easier thing to check. Such as spark plugs and wires. Inspect the wires for any cuts or tears because it may have got wet and shorted.

i took a better look at the wires and found that the inside of the boots were corroded. i cleaned them and put them back on and no more misfire. also cleaned maf sensor and got a code. figured it was an emissions code so i took the neg off and got somethin to eat. started truck and no more code but got it scanned anyway. i got a P0606 ECM internal communication error. dectected internal memory fault, but still no idiot light? truck runs alot better tho

Good job on getting most of the problems fixed.

Check the ECM fuse, if the fuse is fine then try clearing the code. If the code comes back you may have to reprogram or replace the ECM.

checked ALL fuses and cleaned terminals with electrical spray. disconnected computer in firewall, cleaned connector, and visualy checked wires for breaks or problems in harness going to computer. everything is good. i re-wrapped harness and hooked everything up and ran truck. no check engine light but i noticed a slight misfire on low rpms. about 900-1200. still running pretty good tho?

Don't worry about the P0606 code that's just the computer saying it lost power.
