You probably blew a fuse.
Look under the hood for the fuse box and check the BIG fuses.

01 Jeep grand Cherokee I have crank but no start no gauges no power at fuel pump. All fuses good under dash & hood . Turn key to on, 1st warning light low fuel. 2nd key w/ line 3rd check engine help

you used voltmeter at the pump?> or just didnt here it run
do say this...please. details, matter....
it told you low fuel is it? is the fuel gauge near "E"
why not state that first.?
dead gauges, be 1st right, smacks of gross power loss.
right>? not clear to me what no gauges means.
but the voltmeter is #1 no?

did you tests fuse that look ok. fuse that look ok can be bad.
no gauges, means all dead, no movement,
well the fuel gauge must work , does it, does it match reality?
cranks but never runs. good input there.

does not run for the jeep 3 seconds.? (ASD rules)
no 12vdc power to pump, when cranking,?
01 grand WJ jeep usa.
is the skim lamp off, the cluster lamp for SKIM security is first.
it must go out after key turn on, or it will never run, ever.
I can help.
WJ jeep
this jeep has a voltage gauge, it must read 12v keyon
if not power is lost, or battery low.
if cranks that tells me the fues blew.
skim cuts spark and fuel, not cranking btw.
2002 cluster
see that lamp 12, if stuck on car will never start but will crank.
the lamp falses if skim is not working or stays on for ******* key.
IF You can not scan a modern jeep then it can near impossible to diagnose (a hard cold fact)
IF the ASD fails to work, the PCM tells you every time
all 8 ways for it to fail.
but that takes a scan tool (any modern scanner works,)

04 jeep grand cherokee. Blinkers, heater and ac, high and low cooling fans....all quit working at once. checked fuses and relays under hood, inside fuse box good, repaced ignition switch, checked

checked means what, gandering at them
checking real is measuring them, with an OHM meter
fuse that look bad are in fact bad, but look ok can in fact have hair line cracks humans cant see, for sure old folks.
what works and what not is the TOP CLUE here,
1:heater blower dead, blower key word
2: ac DEAD sure it is with #1 PCM logic does that.
3:blinker something , dead, stuck on, one works 3 dont what?
4: high low cooling fans, underhood or dash?
5: does car drive, omg, does it? and not stated !!!!!
6: does car drive at night, headlamps work.
7: air bag on , driving? when? it will just key on, as do all warnings as s self test.
8: anything else work or not work , radio, wipers, and all things.?
9: does engine crank ,ok fast, sounds strong?
10: are head lamps dim.????
11: did you skip things that are dead in your report.?

ID bet you never scanned it , right.

what does GOOFED mean.???? sounds scary that.,!means hacking to me.... why say this.? with no photos show if damage. you cant fix modern cars lacking a scan tool.
I can do magic with my tools but you cant.
i have a full lab. (lab scopes and things you've never seen)
but a scan tool is dirt cheap and is a MUST.
IF the cars power distribution system fails
even a $10 voltmeter can find this, got one?

lets see. the list
1: fuses good, not the gandered at way.
2: battery lugs ok, not corroded.

tell more, get more, lots more,

My radio works on my 2004 jeep grand Cherokee but the time and station don't light up do I need to replace the radio

any thing can be fixed.! (my job that, before retired)
the question (only) is time and money?
if the labor is more than a new upgraded radio.
why fix old.?
is the dash dimmer working, and all other lights on dash bright
the the radio has issues. (stock) if not stock the wires are bad behind radio. the dial wire.
does the radio work? and dial right, can you see the stations, with a flash light, ? then the back light is burned out.
if VFD display or LCD dead , big time $$$ fix.

on mine , 04 i put a new , media only head end.
am/fm , USB , flashcard, aux in, radio
and have micro usb there, very tiny with 4000 songs.
no more discs and radio head is very tiny.

2000 jeep grand cherokee will not start and battery guage is dead

if the other light is ok and the fuel gauge is only dead, may be you have no more fuel, try to refill fuel, if the battery is also dead replace new battery.

Everything has stopped working in my 1993 jeep grand cherokee limited edition. the door locks do not work. my compass/temp gauge has stopped working. the signal lights no longer work. my heat/and air no...

does the car start? if it doesnt...then your battery is dead. see if it"ll jump start at least for awhile, if it does and dies again...your alternator could be bad and not charging the battery.

Check all fuses in fuse panel at dash & also under hood at power distribution box, usually near battery.
