Get a DTC reader with live data option. Watch the live data while cranking and see if your values change. If they don't, it's either a blown ECM fuse or a bad ECM.
If the values are changing, spray carb cleaner into the throttle body while cranking to ensure fuel delivery. If it starts check piwer to the fuel pump. If power is good to the pump, I'd replace the fuel pump assembly with a jeep pump.
If it still won't start, check your spark. If there is no spark, I'd replace the crank sensor. At this point all the basics are there. The only other concerns would be internal. Low or no compression or timing

Is it out of gas? Try spraying starting fluid into the throttle body and see if it starts then. If so, you have a fuel delivery problem. If not, you have an electrical problem (no spark).

    No it had plenty of gas and I added 5 gallons when gauges quit working. None of the gauges move when key is on but engine cranks over. I also checked for error codes and nothing comes up.

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?

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
http://jeepdied.com/cluster2002GC.JPG
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.
we SCAN ALL CARS NOW.
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,)

2001 Jeep Grand Cherokee - Security Key Flashing/ Wont Crank after dead battery


A flashing key symbol normally means an invalid key. Do you have an other key to try? That all the gauges stay at 0 seems to point to a PCI data bus problem. Was the jeep parked outside or at least standing in the rain? Many times water ingress in connector C200 up in the passengers footwell area is the problem. The connector must be removed, cleaned/dried and reconnected. Ofcourse the source of the water ingress must be found, which many times comes from the windshield.

Change the crank sensor the cam sensor and the pcm and the 2001 jeep grand cherokee still is having an issue staying started and the gauges going crazy as well as the windows not working


I cant explain the windows but the stalling can be the wiring harness at the under the hood . you did not mention engine size but i know on in line 6 the harness goes around the rear of valve cover if you move it around it will stall if bad.

Jeep stalls gauges don't work windows and locks and radio don't work


when you state it wouldn't crank, do you mean the starter won't engage or that it just spins over and doesn't start? if no gauges or no starter engagement, then check the battery, battery connections,and the starter for excessive amperage draw. if the starter spins and the engine won't start, then check crankshaft position sensor first. the crank sensor is a more common failure than the distributor or any of the other things you mentioned.

More than likely needs a crank sensor, Try cranking with the crank sensor disconnected, you should not get the dashes in the cluster. The crank sensors take out the communication system of the vehicle

2004 jeep grand cherokee will not start, dash light blink , gauges move back and forth. Battery seem to be ok.


It takes very little voltage and amperage to operate dash gauges. You cannot rely on "seems" when it comes to the battery. A good battery should have standing voltage of at least 12v and be able to "snap back" from a fifteen second 200 amp load. Under load, the voltage should not drop lower than 9.5 volts. Have the battery charged and load tested before going anywhere else with this. then make sure connections are clean and tight. After you get it started, if battery was good, check starter draw and charging system operation. If it does not start, check power flow from key through neutral safety switch and starter relay to starter.
