Hi, welcome to Justanswer.com
Your problem could be linked to the water you poured on it. Often they will have problems right away. and dry out and get better. Lets run your OBD onboard diagnostics and see what shows up? Get these and we can get idae what is wrong
Here is general procedure for getting engine codes by using the flash method.
Turn the key from off to on three times within five seconds. Then watch the CHECK ENGINE lamp. When you hit the proper rhythm ( this varies some from vehicle to vehicle and takes a few tries sometimes ), the MIL will stay lit longer than normal, go out and then start flashing.
Count the flashes. There will be short pauses between sets of flashes to indicate you're going to another number. The last set of flashes will always be 5-5, or code 55, which means end of test. All the codes will have two digits to them. You can repeat this as many times as needed to get a feel for how it works. If the PCM or battery has been disconnected within the last month or so, the first code you'll see is 1-2 (code 12) which indicates a recent loss of memory. be careful not to misread numbers so like 1-2 becomes a 3 or 2-3 becomes 3-2. Do this a few times to check and always write them down for future reference
hope this helps.______________PLEASE CLICK ON "ACCEPT" IF I WAS HELPFUL-OR IF YOU NEED FURTHER ASSISTANCE JUST ASK, THANKS
I am sure youo kow what these meen but here they are
12 is battery disconnected recently. Max of about 50 starts (was it?? if tno look into this)
55 is end of test
fuel pump relay you can ussually switch for horn relay and starter relay with ummm not sure but look and it one has the same pin set it should work for it.
lets look at these
The Crankshaft Position Sensor, or CKP sensor provides the PCM with information about engine speed and crankshaft position. It is located near the bellhousing.
The CKP sensor contains a Hall effect device which sends either a 0.0 volt or a 5.0 volt signal to the PCM depending on the position of the distributor shaft.
The PCM uses the CKP sensor signal to determine fuel injection event time among other things. The engine will not run without the CKP sensor signal.

See Figures 3 and 4

Backprobe with a high impedance ohmmeter between the CKP sensor connector middle terminal and battery ground.
Verify that the resistance is less than 5 ohms. If the resistance is not as specified, repair or replace the wiring as necessary and continue the test.
With the ignition ON and the engine OFF, backprobe with a high impedance voltmeter between the sensor connector middle terminal and either of the end terminals.
Verify that a 5 volt or greater signal is present at one of the two terminals. If not as specified, repair or replace the wiring as necessary and continue the test.
With the ignition ON and the engine OFF, backprobe with a high impedance voltmeter between the sensor connector middle terminal and the end terminal that did not have the 5 volt or greater signal.
Crank the engine and verify that the voltage reading alternates between 0.0 and 5.0 volts or verify that the voltage reading is 2.5 volts (averaging voltmeters only).
If the voltage readings are not as specified, the sensor may be faulty.
Removal & Installation
The CKP sensor is located on the transmission bellhousing. Disengage the sensor wiring connector and remove the sensor wiring hold-down clip from the fuel rail.
Remove the sensor mounting bolt and carefully pull the sensor out of the bellhousing.
Installation is the reverse of removal.

Make sure that the ignition is OFF, remove the distributor cap and turn the engine over by hand.
Verify that the distributor shaft turns. If the distributor shaft does not turn, the engine must be checked for proper mechanical operation.
Backprobe with a high impedance ohmmeter between the CMP sensor connector middle terminal and battery ground.
Crank the engine by hand and verify that the voltage reading alternates between 0.0 or 5.0 volts.
Install the distributor cap and crank the engine with starter. Verify that the voltage reading is 2.5 volts (averaging voltmeters only).
Disconnect the negative battery cable and remove the intake air tube if necessary.
Remove the distributor cap and the rotor.
Disengage the CMP sensor wiring connector and carefully lift the sensor out of the distributor.
Carefully place the sensor into the distributor. Make sure that any alignment notches or tabs line up properly.
Install the distributor rotor and cap.
Engage the sensor wiring connector and connect the negative battery cable
