Will not start after rolling in mud hole

Vehicle: 2002 Wrangler Sport w/ 4.0 L and automatic transmission

New to Jeeping. Rolled onto the passenger side in about 18" of muddy water. Got it pulled out pretty quickly, but made the mistake of briefly attempting to start it. Yep . . . not a good idea. A friend explained hydrolocking. The throttle body was full of muddy water. Pulled the plugs and ran the starter while flushing with clean water. Maybe 1/2 cup of muddy water pumped out the spark plug holes. Put the plugs back in and attempted to start. Wouldn't turn over. Pulled plugs again and got a little more water out. Put plugs back in and this time it started and ran for about 10 min while giving it a little gas. As soon as we let off the gas, it cut off and we can't get it started again. The engine is turning over, but will not start. I feel like it's an electrical issue.

We have changed the oil and the plugs. Also opened up the fuse box and dried it out. Verified all the fuses are good. Not sure how to check relays. We can hear the fuel pump running.

Wow. That is a rough initiation to Jeep off-roading!

It is encouraging that it started and ran for a bit after you cleaned everything out.

Have you cleaned out your IAC? Sounds like a lot of things probably need cleaned up, starting with the intake and TB/IAC.

At this point I think us pull the oil pan and spray down crank, bearings and oil pick up tube with parts cleaner. I'd buy cheap oil and flush the engine using the starter- drain it and do it again if the oil smells of cleaner and comes out gummy. The reason is, if you tried starting it and allowed water past the cylinders, you may ha e created a gummy residue that will act like a hydro lock. It does not burn out easily. Relays tend not to be affected much. After flushing, I'd start checking out the ignition system.

Based on Harry's post, I took the TB off and cleaned it and the IAC. Still turning over and sounds like it's on the verge of starting, just won't start.

Hmmm. How long has it been drying out? It needs air, fuel, and spark. I figured if it needed the throttle pushed in to run, the IAC was plugged. Sounds like that helped, but maybe more crap got in in the meantime and fouled your new plugs? Wish I was there to help instead of spitballing here. I'm assuming you changed/cleaned your air filter, or tried starting with it off after you cleaned the IAC?

Did you dry out everything inside the distributor cap rotor All the innards ? Check the plug wires at both ends including the coil wires. Make sure all that is dry!

It's an 02, so it has a coil rail, but the same idea applies. Blast it with WD-40.

It's been drying out since Friday evening. I remove the coil rail, blasted it with WD-40 and then blew it out with the air compressor. Still the same. The engine turns over and sounds like it wants to start . . . it just won't.

It air filter box was full of water. Took out the box and tube going to the intake. Currently, the throttle body is open.

Pull a plug out then ground it to the block. Have a buddy turn the engine over. Look at the plug to see if it sparks.

Clean the crank sensor...it's really easy for mud to get in there and cake on the tip.

Like these guys are saying. I would try new plugs again. After years of snowmobiling and personal watercrafts I know how easy it is to turn a new set of plugs into junk with very little moisture..

It's halftime of the Steeler game, so I'm going to think out loud for a minute and hope it helps. It doesn't look that bad, and was running after. Cleaning the pistons with water is better than nothing, but I'd use WD-40 or kerosene (have used WD many times in swamped 4-wheelers and once in a friends Jeep that was left in a creek up to the windshield for 13 hours, and the dumbass tried to start it repeatedly). I'd pull the plugs, spray WD for a few seconds in each cylinder hole, then turn it over with the plugs out and repeat until it came out clear. Let it dry out (can help with compressed air, but leave a gap between the nozzle and the hole), blast any sensor with mud on it off with WD and let dry. Install NEW plugs and see if it starts. Change all fluids, run some engine flush and change the oil a few times.

I thought about fuel being the issue, but he said it ran for 10 minutes after... So I dunno. It wasn't in deep enough for water to be in it .?. May as well try, it's easy enough.

I don't know for sure. Rhino's are notorious for vacuum locking the fuel pump, but I haven't heard of it in our TJ's. But then again, I have a lot more experience with mud and water than with roll overs. If that's all it takes, it's worth a shot, or using the Schrader valve on the fuel rail.

If it was me after I got all the water out and everything cleaned up I would try a compression text. Don't know if trying to crank it over with water in the cylinders could have bent anything. Everyone says all you need is fuel air and spark but forget abound compression. I am willing to be you have compression if you got it to run for 10 minutes. Just guessing here that's all.

After watching that game, I'd rather be working on your Jeep. Any progress?

No problem removing the gas cap. Should I try taking the plugs out and flushing through the TB with kerosene?

Isn't the evap canister under the hood, on the passenger side in 97-02? Maybe you got mud/water in your fuel lines. There would have been a couple minutes worth of clean gas in the feeder line from the tank to the injectors to explain why it ran for a while. With the pump on, let some gas out of the schrader valve on the fuel rail. Catch it in a clear cup and see if it looks cloudy. Let it sit for a while and water may separate out of it.

spray a little starting fluid in there and see if it fires up, if it does you more than likely are starving for fuel. Not sure but seems like there is a fuel pump reset that shuts off fuel after impact or rollover. someone that knows for sure may answer shortly.

I hate to say it, but I have experienced something that was quite similar. I didn't have a rollover but I did drown the engine. By the time I was done drying out the engine (which took about a day and a half), I was blowing chunks of glowing debris out of the exhaust. everything from the cat back, was glowing red hot and I couldn't get over 25 mph. After cutting the tail pipe in front of the cat, I was able to hit 45 mph and shoot blue flames out of the exhaust. Needless to say, I had to have the insurance step in and took it to the dealership where they kept it for about a week and reported that they saw water where they have never even thought of it being before. If you have the means, I would recommend getting it to a professional so they can go over it with a fine toothed comb. Just my two cents. Good Luck!!

x2--it doesn't look like there is anything there that would cause a roll over.

I think I'm running out of options. Removed the spark plugs again and flushed through the TB with a jug of WD40. Verified that there is fuel pressure at the valve on the fuel rail and verified spark at the plugs. It still turns over and sounds like it wants to start, but doesn't. There is exhaust coming out when we are trying to start it, so I know the system isn't completely clogged. The only thing left that I can think of is that we are not getting compression. I don't really understand it because we had it running Friday night. Flushing it again with WD40 this afternoon. Anyone have any other suggestions?
