    are sure it's not your radiator fan? they will run after your car is turned off until it's cooled down, but 4hrs is way to long. it will drain battery.

To check the radiator fan you can look in the fuse box area and find the fan relay, pull that black relay and if the fan stops thats what it is. if it doesnt then its something else but probably the fan and should be electronically diagnosed, atleast you can check to see if it is that by pulling that fuse according to the diagram on the relay cover underside.

Where is the emergency fuel cutoff switch reset button on a 2005 Hyundai elantra

It doesn't have one ! Do you know what a automotive relay is ? Videos on youtube on how to test a relay ! The relay has a set of contacts inside and a coil of wire to make a electromagnet . If you pull the relay out of it's socket in the under hood fuse relay box you will see 4 or 5 pins ! Two of these pins should have B+ voltage . The other two go to the fuel pump or the PCM - engine computer . On the bottom of the relay are four numbers 30 & 87 these are what is called the load side of the relay . If you were to jump these two spots where the relay plugs into , this would send B+ voltage directly to the fuel pump . You will also see 86 & 85 , this is the control side of the relay . One will have B+ voltage and the other would show open , this is the computer part of the relay control side.
The PCM will turn on the relay for two seconds when the key is first turned on , this is to prime the fuel lines and fuel injectors. Then when cranking the engine over it energize the relay if it see's a crank sensor input ! Does your vehicle have spark ? If not could have a bad crankshaft position sensor !

Where is the fuel pump relay and fuse on a 89 jeep Cherokee? I had the pump replaced six months ago but now I don't hear it come on any more and it wont crank. I just did a tuneup on it and it ran fine for...

the relay is in the small fuse box in the engine bay. relays can burn out and lock up in power flow. if this has happened it can also burn out the pump as there is no fuel being moved as the fuel line is cut of by the valve when engine is not running.

Engine is not getting fuel.

Turn the key to the on position but dont start the car. Get a friend to listen under the car to see if the fuel pump is turning on. It makes a "whirring" noise when functioning properly. Check your fuel pump relay under the hood in the fuse box. If thats not the problem, check your fuel filter and hoses and observe if they need replacing. Hope this helps!

A sudden stop of my car santamo model 1996 due to no fuel to the gasoline engine

look for the fuel cut out switch, normally on these under the hood, or fuel pump , or relay failure, if you stopped suddenly or hit a bump then the cut out, if thats not it find the relays and pull out and put back in in case of a bad connection, then work back, if you switch on the ign you should hear the pump make a noise if its working

Were i can find the fuel pump fuse because no juice on the pump or if any body knows the problems let me know thanks

There is no fuse for your fuel pump. There is the main relay, located under the dash, near the fuse box. It has to be checked electrically to verify that voltage is available to the pump.
Since you say that no juice is going to the pump, I assume that you have had someone listen back there (the pump is in your fuel tank) to see if they hear a whirring noise when you turn the key on without starting the car. If there is a whirring noise, then the pump is running. If there is no whirring noise, either the pump or the main relay is bad.
Hope this helps you a little.

Where is the fuel relay on a 1998 Hyundai Elantra Wagon located

under the driver side dash is the ECM, just above it should be a small cluster of relays. i forget which one is fuel pump, but if you plunk them out one at a time and listen for fuel pump whirring when you put key in the on position you can isolate which one it is.
also, are we totally sure this is a fuel problem?...
