Starter will not crank the engine?

If the water was above the hood, the engine sucked water into it through the intake. First, if I am correct, the starter will no longer turn crank the engine. If that is correct, then you have water in the cylenders. Remove the spark plugs (mark the wires) and crank the engine till all water comes out. Next, change the oil because it is most likely contaminated with water too. Remember, water doesn't compress like air, so there is a change you bent a connecting rod or caused other internal damage to the engine. You will know once we get the water out of the engine.

Once the water is out, spray some penetrating oil into each cylender to help prevent rusting. Allow the plugs to stay out for at least over night so any water can evaporate. If you have a compressor, try to blow out any water that still may be in there.

Next, check to make sure you are getting spark to the plugs. Since you already have them out, you may want to just replace them. If you have spark, replace the plugs and keep your fingers crossed. If the engine starts and there is no knocking or ticking, you save it. If there is knocking and rough idle, chances are there is internal engine damage.

Please note that I am basing my response on the fact that the engine was covered under water while it was running which would have caused it to take in water. If the starter is turning the engine over and it won't start, let me know. Don't forget to change the oil before running it.

If you have no power going to solenoid and can jump it to start check neutral switch in CJ's drawing or the relay may be bad which you can quickly check by swapping another relay from PDC.

Don't crank it anymore until you remove the plugs. The cylenders are full of water and it will cause internal damage if you try to force it. Basically, you have hydrostatic lock. Remove the plugs and crank it. You will see water will come out of the cylenders and the engine should crank unless damage has already been done.

Brooke, trust me. Remove the plugs, mark the wires so you can get them back to the correct cylender. If the engine cranks with the plugs out, I am correct.

Let me know what you find.

Then check wire leading from ignition switch for power the switch may be the problem then.

Get your test light and where single arrows are see if you have power with key on in those sockets. then where double arrow is have someone turn the key to start and see if that has power. it may be corrosion on relay or a PDC problem. I think the click you hear in dash is from the power-train module telling truck to start. you will need the relay out to check this and you can correspond with the the numbers which should be on bottom of relay. if you get power on all positions except where I have not marked it. It may be a fuse box problem or corrosion and it is not making good contact with relay. You may correct this by tweaking that one prong just a tad and cleaning any or all corrosion off as well as using dielectric grease on prongs for better contact. If there still is no power at unmarked position then it is either the fuse box is bad or the wire leading to starter has broken someplace which you can check with an ohm meter. i am also sending on how to check a relay along in link.

It was my actuator pin in my ignition-thank you very much-now I see my fuel tank skid plate is in very bad shape will it pass safety inspection if I put a couple of adjusting straps under my gas tank secured to the frame on each end thanks
