    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.

Revs to 3000 RPM and quits. when try again no spark

Was this a one time thing? Are you able to try at a later time (hour later? day later?) and it does it again? It sounds like a couple of things. When a cold engine starts, it will rev up to get to a safe operating temp, although I've never seen it go that high. It should rev down after a couple minutes to a normal idle speed (650-800 RPM). If it revs up and stays there too long (20-30 seconds), it may shut down because of several things: it cannot see engine speed because the crank sensor has failed, the temperature sensor has failed, or the cam sensor has failed.

The most likely cause is no fuel due to the fuel pump not running. Check the 20A fuse (#16) in the power distribution box located under the hood on the drivers side front. If it's good, check the fuel pump relay (#30) in the same box. Place your finger lightly on the relay and have someone just turn the ignition on (not start). The relay should click and you will feel it. If the fuse and relay are good, then check the the fuel pump shut-off switch (also called inertia switch).

Did you or someone else hit the curb really hard or run through a big pothole right before the car stopped working? If so, you may have tripped this switch. It is designed to kill the fuel pump in the event of an accident, but any significant bump can trip it, especially if it's worn. It takes a bit of force to trip it, but when it does, you will never be able to start the car again until this switch is reset. It is located in the trunk on the passenger side behind the paneling. If you look at it, there will be red button on top. It should be down inside the switch body (you can still see and touch it, though). However, even if it is down, the contacts get old and might prevent the fuel pump from coming on. Smack the switch with a wooden handle. It should cycle and the red button pops up. Now press this button down firmly. Turn the ignition ON and OFF about 3-4 times (do not attempt to start during these exercises). Each time, listen for a whining or whirring sound. Now try to start it. If this solves your problem, you need to replace the fuel pump cutoff switch (inertia switch). If you did not hear any sound and the car did not start, then you might be looking at bigger issues. Although sensors are simple little things, the work needed to replace them is crazy. But a failed sensor should throw a check engine light.

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?...
