Re: 1998 jeep cherokee 4.0
Dunno why but Jeeps (we own several) seem to love to develop bad battery connections; when that happens with us, I take my trusty Chinese (cheap ****) battery terminal cleaner and scrub the clamps inside and out.

check the battery for full charge, you should have a minimum of 12.4 volts, once its charged ( I'd have a parts store do a LOAD test on it ) start the vehicle, and check the posts again, it should be giving you a reading of 13.5 to 14.5 volts,, if not, and you've cleaned all the contacts you have a bad alternator
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!!
Check your fuel pump ,fuel lines,.One of the most overlooked starting causes is fuel delivery. Find the
fuel rail to the injectors. Assuming you don't have a fuel pressure gauge, remove the dust cap on the fitting on the fuel rail and press
the center pin in the valve to see if there's a good amount of pressure
for a very brief second. There will be no continuous pressure unless
the engine is running or is being cranked over. Have somebody crank it
for you for a second to see if high pressure is present.
first look at the fuel cutoff switch usually located in the inside
stowage compartment of the vehicle. See if the reset button clicks when
you press it. Next check the fuel pump fuse and relay, and finally the
pump itself could be bad.
there isnt one. if the fuel pump does not run, ck the ASD and FUEL PUMP RELAYS. Turn the key on and listen real close to the fuel tank, see if you can hear it come on the 2 seconds, Sometimes you can rap on the tank with a mallet or board when cranking, and this will knock it loose, it that gets it running you will need to replace the fuel pump.
Disconnect and replace fuel filter.With filter disconnected have someone momentarily turn key to on position to see is fuel pump is working.Make sure you have lots of rags,a drain pan and safety goggles on
