2003 jeep grand cherokee will not turn over

When the key is turned the instrument cluster lights up and gauges come on. You can hear the electric fuel pump cycle on-off, but that's it. Starter doesn't make a noise at all. Battery is under 3 years old and seems fine. Not sure what direction to start looking? Computer module, neutral safety switch, starter, ignition switch.

Constant 12-volt power is applied through 40 A FUSE 8 in the power distribution center (PDC) to the engine starter motor relay and through 40A fuse 14 to the ignition switch. If the park/neutral position switch is connected to ground, turning the ignition switch to START causes 12 volts to pass through 10A fuse 31 in the junction block and the engine starter motor relay coil to close the relay and apply 12 volts to the starter. Any of the parts mentioned could be open or defective.

have same problem, ratan9 solution is pretty junk and I dont know why waste time posting it. After talking to local shop, to "test" the neutral safety switch, try to start in neutral, try to move shifter "farther" into park and turn key, listen to any clicks possible. If moving to neutral starts it you've got a bad switch. All the searching i've done it's either the safety switch, the ignition switch or a short in the harness somewhere

SOURCE: 2002 pontiac montana will not

Did you got the ignition switch checked.If ignition switch itself is getting short, then it will not let the car to start.Also get the voltage at starter relay checked.If the starter relay is short, then it will not let the car to start.------------- Test the voltage at starter.If there is proper voltage to starter this will confirm, whether the relay is issue or not.----------- To test the starter try this procedure.
--------- Measure the voltage at the starter solenoid. Place the red probe on the positive battery terminal on the starter solenoid and place the negative probe on chassis ground. Have someone turn the key switch to "START" while you measure the voltage.The voltage should be approximately 12.6 volts. If the voltage is correct, there is a problem with the starter. Remove the negative battery post and check the connections on the starter.But if voltage is very low and less that 12 volts, this indicates its faulty solenoid.If you follow the wire from starter solenoid, it will reach the starter relay.That starter relay is a 12 volt part.If there is no voltage to starter or solenoid then its faulty starter relay.----------
The ignition switch is also a 12 volt part.Check the voltage at ignition switch wiring harness, there should be 12 volt.If not the switch is the issue.-------Also try wiggling the key in ignition key lock cylinder , many a times the lock cylinder gets shorted or out of line or bit loose internally.--------- Getting this possibilities checked will point towards the faulty component causing the problem.-------- This will help.Thanks.Helpmech.

SOURCE: 95 jeep cherokee country 6 cyl auto. wont crank all the time

Sounds like a bad starter, why did you replace the crank position sensor? If the engine will not turn over at all and it sparks with trying to jump the solenoid with a screw driver it seem as though the starter is bad. First you solve the solenoid problem when you jumped the solenoid with a screw driver sending fire to the starter. Check the cable connections to the starter if they are good replace the starter this should fix your problem.

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,)

1996 jeep grand Cherokee starting problem. Turn ignition switch on - no fuel gauge, volt meter and no primary coil voltage. Move switch on and off multiple times then gauges work and it will start.

The most likely fault is a bad ignition switch. The electrical portion of your ignition switch has probably failed...well, only part time failure, jiggling the switch on and off will cause it to make contact again. Everything you say that doesn't work, should be working just by turning the key to on.
Are you looking beyond the switch for something not triggering? Don't make it too complicated: switch on, and the pcm should be powered up (along with dash gauges being on and the check engine light is on.) That means you should now see that voltage at the ASD relay, as it is now "on" and power is going to the coil and to the injection system. Your switch is the only thing tying everything together. If it doesn't work, nothing else works. This sure sounds like the electrical portion of the switch, not the lock cylinder portion, but examine carefully. Some ignitions have a metal rod from the lock cylinder to the electrical portion where the rod moves a sliding bar across different electrical contacts. Sometimes this mechanical linkage can foul up and cause switch problems.

2001 jeep grand cherokee,pulled dash out to change blender doors, put it back together, now shows gas gauge empty, and lights up, and key with circle cross on, won't start.

You will need to remove the cluster and make sure you plugged in all the connector to the cluster, the antitheft system runs throught the cluster also and you said fuel gauge doesnt work so i would have to say theres a bad connection or you forgot to plug a connector in. good day.

I have a 2003 Jeep Grand Cherokee laredo, 6 cylinder 4.0 that will not turn over, but cranks. The check gauges light and check engine light are both on. Using the key/odometer on/off I only get, "done." I...

You need to first determine if the problem is with spark or fuel system. Check for spark at plugs, same at coil. You can spray carb cleaner into the throttle body while cranking the engine and see if it starts. If it does, then the problem is in the fuel system.You can use a digital multi meter to do individual component tests as listed in haynes or chiltons manuals and to check voltages where necessary. Check all the fuses inside and outside as well as fuel and auto shut down relay. Most common failure is the crank position sensor, but if you replace it without testing likely it won't be that. When you turn the key, you should be able to hear the fuel pump running. Wish I could give you more but I don't have enough info and testing is far better than guessing!!
Good luck

2001 Jeep Grand Cherokee won't Turnover

Jeep 2001 Grand Cherokee turns over but never starts. Doesn't run for 2 seconds and turn off. Immobilization indicator does light, flash once and remain on. All analog gauges on instrument panel are not functioning. Everything else electrically works in vehicle.
