Need help figuring out what was damaged

I had been on the road most of the day. My 92 Jeep had ran nicely up the hill I have to top on my way to work. It ran great all day. It never once got hot. I was going down the highway and suddenly, I lost power. I tried to throttle the accellerator with my foot and got it to a spot where I could pull off and it died there. Looked under hood, the serpentine belt had frayed and had wrapped it'sef around the fan, stopping it and burning out the water pump.

I have replaced the water pump and the belt, but when I tried to start it, it wont start at first. Then when it starts, it dies the second I put my foot on the throttle or if I tap the thottle when it first starts, sometimes it catches and I can rev the motor up to around 1500 to 2000 rpms, but the second it goes under 1500 to 1200 rpms, it slowly dies. Sometimes it revs up all by itself and then dies. It runs like it was running only seconds before it died. (and it only ran bad for less than a minute.) Any idea???

three things come to mind. Tps, crank sensor. And a possible fried alternator. Can you spin the alternator freely by hand ?

92... that should be obdI there is info on here about checking the tps. A failed crank sensor will have similar symptoms.
Dont rule out a bad alternator it still may not be charging jeeps done like low voltage.

Thanks.. I guess my next question is...Can over heating cause either the tps or the crank sensor to go bad.

Heat will cause them to fail but 1 time overheating I would say its unlikely. If you think about it if you shut your car off on a hot day the Underwood temp will continue to rise past operating temp .

That makes sense. Im thinking that whatever happened to the car as it overheated that caused it to go from running excelllent to a sputtering stall is the same thing that is keeping it from running right now. As I mentioned, a piece of the serpentine belt got wrapped around the fan and burnt up the water pump? That's the basic catapult. I am going to test tps, and all the other sensors tomorrow. Thanks ;0)

A few thoughts here.
First simple, are you sure the belt is routed correctly?
Second is if the belt failed that badly it was probably loose for some time. Perhaps you battery isn't up to snuff..
Has the Crank sensor ever been replaced? If not it's way past old enough to do just as maintenance..

Thank you for your thoughts.. to answer your questions: I am sure the bet is routed correctly. I have diagram. The crank sensor has never been replaced. I am planning to replace it and several others on payday. And yes, I guess it could be possible the battery is not up to snuff. I'll try it with another battery that I have available and is fully charged.

Thanks again.

On my 92 it got hot and wouldn't restart and run. Well ok it would start for a few seconds and die. Turned out to be the fuel pump resistor. Its in the drivers side fender. Jump the 2 wires together or just hook them together. See if it runs. $5 part. I keep 3 in my rigs.

I tried to jump the resistor but it still did the same thing but you got me thinking about fuel more seriously so I tried a little starting fluid and it started right up and ran like a champ for a few seconds so as it turns out, it is a fuel delivery problem.

I pulled the filter a while ago, and when I saw what came out of it..it was white and not clear at all. It looked nothing like gas.... the picture below is of a pan (which was clean before I let the gas into it) where I let the gas out of the filter. The white on the bottom and the white splatter on the sides is the gas after it dried. I swiped it with my finger and it's like superfine chalk! The funny thing was I had just checked my filter and emptied my tank last week and didn't see anything like that at all. I'll admit, I didn't drop the tank, I pumped the gas out till it was empty, but still didn't see any thing in the gas I pumped out and I had to pump the last of it into a large pot so I would have seen any wierd stuff that would have came out of the bottom. But I did a bad thing when I filled up last time and I'll never do it again! I filled up at the local casino because they were giving $15.00 to play for a receipt from their convenience store for $25.00 or more and I used the cheapest gas. (I had filled up with premium days before and had no problems. It ran great). So I am thinking that though the obivous part of the problem was the piece of belt that wrapped around my fan and burnt out my water pump, the thing that is happening now is ...bad fuel??? Maybe I need a new filter and I already knew I need a new fuel pump.. so I have dropped the tank and unattched it and am going to clean it out completely. Then I'll buy a new filter and pump and hoses and hopefully that will do the trick. Does anyone know...??? Will bad or watered down gas dry white?? Or if not, what would cause gas to turn white and dry like chalk??? Thanks for all the help already ev1@@

You have an external filter !!! Wish the new ones had that. I have seen gas dry white like that but I can't remember what caused it... go back and buy a gallon of it see if it dries white.

???

I've never seen or heard of gas drying white like that. I HAVE heard of contaminants getting into underground storage tanks, but usually just water.

If they were selling a ton of gas, you might have gotten the dregs from the bottom of their tank. Nothing to do with premium vs. regular, just an empty tank pumped down past where it should have been.

If that stuff is in your tank, it's in your pump and your filter. I'd replace those first, then see what's what.

If it got past the filter, it would probably clog the injectors.

The thing with the belt might just have been coincidence.... It does happen.

But it always bothers me!

I dropped the tank and emptied it and the gas was a little foggy but there was no white residue whatsoever. However, the sock on the pump was off and falling apart, what was left of it was laying on the bottom of the tank. But no white residue there either. I put a little of the gas from the tank in a beater we have and its running fine. Ordered a pump and filter for tomorrow.

I know what you mean! It has to be coincidence and actually a very good one because if it wouldn't have died when it did, the motor would have overheated and more damage would probably have resulted. As it was, it never overheated. It just started to sputter and then died. I actually thought I had spun a bearing because of the noise coming from the engine. I was suprised to find that piece of belt on the fan and the water pump pully was actually bent away from the motor!!! So I guess it's another example of things working out in the end. Though I won't know for sure till I put the new pump and filter in tomorrow.

Read the link and that's exactly how I found it. It dried really fast and felt like chalk when I rubbed my finger on it. I really wonder what causes that??? I doubt it was the sock. Though he did have that same symptom. but the sock turning to white chalk??? I dont know...all of the sock was there.. but it was just in pieces.

As for the gas being on the stove...... I just sat it there to take the pic. lol... good question though ;0)
