Question about 1994 Jeep Grand Cherokee

1 Answer

Our jeep isn't getting enough fuel to keep running. I'm not sure if it's the fuel pump or the filter. I've checked the fuse and it's fine. Wondering if the fuel pump is inside the tank, and also where is the fuel filter is located

    I had one of these.. after replacing the fuel pump, filter and numerous sensors we found by reading the manual that it was the security alarm system that had to be reset. It should tell you in the manual how to do it if in fact yours has a system.

Filter should be on the left side frame rail back near the tank . If not, then it's on top of the pump/sending unit on tank.

listen at your fuel tank to see if you can hear the fuel pump running
if it isn't check your fuses as well as your relay if these seem to be ok then it's probably the fuel pump

My fuel pump on my 99 cougar v6 only runs for a half second then shuts off I've replaced the filter , the pressure regulator valve , the pump and it still does the same thing . could I have a ecm prob

Generally, the computer only runs the pump long enough to start the engine and build oil pressure. After that, the oil pressure switch keeps the pump on, most of the time by supplying a ground to the fuel pump relay. This is a built in safety thing, when the engine isn't running, the fuel pump shuts off. Most public libraries have Chilton's manuals, or you could pick up a Hayne's manual at a store like Autozone. These books can help you locate the relay and oil pressure switch, as well as provide wire colors for your specific vehicle.

88 dodge truck ram 50 2.6 L engine. Changed spark plugs , oil, fuel filter underneath near rear tire. the problem is when im starting or warming up vehicle it runs fine but once i get going or...

There are 2 fuel filters on the Ram 50's. One bolted to the frame under the bed/box (near the rear tire) and one in the engine compartment on the fuel line going to the fuel pump.
Although, it sounds like the choke isn't functioning properly. Once the truck has reached operating temperature remove the air filter and check to see if the choke is completely open. If that is functioning correctly i would check the timing. Which should be at 7* BTDC, although from personal experience with my own ram 50 (an '84 with a modified 2.6) I've found they run much better with the timing set to 9* BTDC.
As the 2.6's get higher mileage, the timing chain stretches and the guides (a poly/plastic guide glued to an aluminum bar) wear and allow slack in the timing chain, throwing the original settings out of wack. You can compensate for it by adjusting the timing, but in the long run (if it fixes the problem) i'd recommend installing a new chain & guides.

My 1999 Jeep Cherokee classic runs but cuts off and I've replaced the fuel pump three times.It runs good for a while then cuts off.I was wondering what else could it be ?

Have you tried to replace the fuel filter.....sometimes this inexpensive item is often overlooked! It is possible you have some debris in it that gets in the way intermittently and cuts off the flow! If you found this answer helpful please vote so! Thanks

It seems I'm getting too much gas,my plugs are fouled out. The truck runs fine for 5 min when it's cold, then it will foul out if I don't keep giving it gas.

Sounds like your actually not getting enough gas, then your fouling your plugs because something isn't firing right. When your vehicle is cold it uses more gas to run smoother, then when it warms up it is leaning the fuel out and you have to keep giving it gas because it wants to die from not getting enough fuel. Whens the last time you've done a full tune up? or timing adjustment? check easy things first like air filter, plug wires....I'm sorry but I think it's going to be something a bit more difficult, atleast first start with your air filter.

Is the fuel pump located inside the tank on a 1989?

dont go replacing everything...thats gonna get expensive real quick...especially that fuel pump. yep...the pump is inside the tank. stand out side your truck,and turn the key over,but not enough to start it. you should haer a whirring sound lasting about 2-3 secs. come from the back of the truck. this is the fuel pump powering up. if you dont hear it...then the pump is bad. if you do hear it, have a friend turn the key while you look at the carb/injectors to see if fuel is spraying thruthem,if it isnt....then you have a clogged fuel filter. BUT...b4 you do any of this...check your fuel pump relay and fuse to make sure they are good. a 10 cent fuse beats a 200 dollar pump any day.
keep me posted!!
