Need advice BADLY!!!!!

[ranedoss27]

Long story short...Went off roading, drove into a mud hole that was to deep and sucked water into the intake...truck died and sat for about 15 min. Got it started and ran for about 5 min with my foot on the throttle but would only rev to like 3000 then died out and hasnt started since...checked the oil and it had no water in it...pulled the plugs and cranked it to get out any water out and then replaced the plugs. the engine is getting spark, fuel and will turn over but doesnt sound right. all i can think of, is to replace the oil, filter and do a compression test...maybe its electrical??? any advice would be greatly appreciated!!!!
thanks, dane

My first guess would be a wet electrical part.

Hydrolocked. Engines don't like things that can't be compressed in the cylinder.

I'd almost rule Ignition out if it's a 4L. EDIS is about as water tight as you can get. If it's got a distributor, take the cap off-inspect.

Also, if the stuff got into the engine it would have had to go through the filter. Muddy water turns into what when it dries? Dirt......not good for a filter.

Check simple things first. Then move onto the more involved items.

Thats what im hoping for Big Jim....I figure if it was mechanical it would either start and run or never would have started after the first time it stalled out....then again im also not an expert so i could be entirely wrong...lol

 

[ranedoss27]

yah the filter was the first thing to come off. it was soaked and so clogged that when i first go the engine restarted it warped the shaped of the filter, also the maf sensor seems to be ok too....

Water in the gas tank, filter, oil, block, or etc can cause damage.

If the water was cold, check your block, you might have cracked it (worst case scenario). Could happen, the same thing can happen to pots and pans when cooled very quickly. Even the the iron ones.

I think big jim and kip have it dead on. when the engine cools the sensors are in open loop, some water could be in the wire connectors. when there open it would run.

water in the tank, water is heavier than fuel, so it goes to the pump pick up, but it would run for a breaf sec. there is good fuel in the lines and filter.

and all RVB's fuel filler necks are imfamious for spliting at the tank.

if it was hydro locked it wouldent turn over, and or thrown rod.

so you guys are saying i should rule out a mechanical malfucntion...ie, bent valves, rods, etc...if so thats good...now i just need to figure out if it is an electrical problem and where its at. i checked all the fuses and there good. the only thing is that after the intial stall out, i got the truck running for a few mins. i had my foot to the floor but the truck would only rev to like 3 grand and then i thought it was running better so i took my foot off the throttle and it died and hasnt started since..any thought guys?

pull all the connectors apart and clean with elect cleaner and put them together with dielectric grease and take the grounds apart and sand them metal to metal and troubleshoot from there. Depending how deep and long it sat in water I would change the oil in the gearcases you could possibly pulled water in them as the water cooled them down.

 

[Big Jim M]

In neutral or park your vehicle's computer holds the rpm to a maximum of three grand...or therabouts.
I'd raise the hood and put a fan blowing on the thing for a few days and then see if it will start. If there is water in something you need to dry it out.

You guys are awesome. thanks for all the advice the truck wasnt submerged very long. i drove through a mudhole that was about 75ft long and about 3ft deep. it didnt stall until i came out of the hole and this other truck cut me off and i slammed on my brakes and then the truck stalled. either way, im going to change the oil and filter. Also now when i crank the engine i can really smell fuel under the hood, even if i only crank it for a few seconds but i dont see it leaking from anywhere...does this mean anything?

Flooding? No spark? Just a guess.

 

[ranedoss27]

its got spark....n the smell of a lot of gas could mean flooding

x4 hydrolocked. It doesnt take much. his compression reasoning is right on the money, on top of the fact that water is thinner than oil and washes the cylinder walls. everything lockes up. My mustang took on water and never started again. If you pick it completely apart right now you can prolly save it but once the rust sets in......

 

[ranedoss27]

so i pulled the intake off and it was full of water and mud...not good at all. also i thought if it hydolocked it wouldnt start again? The truck was restarted after the first intial stall out and ran for a few mins under half throttle until i took my foot off the gas and then it stalled out again. what are the chances that maybe the ecu went bad?
