I have zero power.

121,000 miles on the car.

Inspect and test all the fusible links and also the ignition switch

Where is the fusible link located and Does the vehicle have a auxillary fuse?

You need a repair manual you got a long way to go or just bring it in and have it fix-

How much does it cost to be repaired?

Dunno it varies with location both parts/labor

Can this be done without seeing a mechanic? Where is the fuse link located? I am in Columbia, Maryland.

My jeep doesnt start right away. I have to turn it at least twice. Got starter tested, thats not it. spark plug tightened, worked for about 5 minutes then back to not starting right away. when the spark plug was tightened the check engine light went off but problem starting persisted. i heard it could be the fuel pump. anything else it could be? what step should i take now to avoid wasting money on the wrong problem.

Hello –

To better assist you is your model Freedom, Laredo, Limited, Overland. Also please provide your engine size in liter and the 8th digit of your VIN.

Please go to Auto Zone (AZ) or O’Reilly’s (OR) and for FREE they can pull the codes to the car. Most important: Once they check your codes, if they find something and you don’t get it fixed and need to get back with us, please make sure you tell us exactly what the code was, number and all. Example, if the code was E0568 O2 Sensor bad. Then make sure you give us all of that. While there for FREE also they can bring their tester out and check your battery and alternator.

We need to figure out if it is electrical or fuel related. Pull a plug wire off of the spark plug and insert something into the end of it and have someone try to start the car and have the metal object really close to a piece of metal on the engine and see if you are getting a good strong popping blue spark. Try several plugs. Don’t have your hands on any part of the metal!!! If there is no spark, then it is electrical.

If you are getting good spark then spray some starting fluid in the throttle body and try to start it and see if it tries to start then.

04 grand Cherokee won't start. Just replaced governor pressure relay and solenoid due to 1756 code. Also replaced spark plugs. Ran great for a day. Now won't start and no codes. Thinking might be MAP sensor?

If its cranking over and will not start check the fuel pressure if its within specs and injector pulses and spark.

Checked fuel. Ok. What is the best way to check spark with coil rail?

Use a spark tester-ST-125

Disconnect the plugwire on the sparkplug and ground it and have helper crank engine over and look for a snapping blue spark

Is this a DIS or COP ignition system?

It was the crankshaft sensor got a new one started right up!

Good job!

My 04 Jeep Grand Cherokee won't start one day, before breaking down, I had problem with the Jeep starting. I have replaced the starter and still won't start. I noticed that the positive battery cable became hot, checked all the fuses and relay switches, all OK. I disconnected the ignition wire harness and still the positive battery cable became hot. Their is a short, but I can't pin point it. I connected the jumper-cable directly to the starter, battery positive to positive starter terminal and battery negative to engine block, this started the vehicle and the positive battery cable didn't heat up, but once I turned off the vehicle it heated up and won't start. What would I need to check next?

Sounds like a bad ground try checking ground cable. And any body ground that comes off ground. Replace if in doubt.

Cop

Don't have help with testing coil rail right now. Any other thing I can test?

Also tested all fuses. Will the governor pressure sensor or solenoid not allow the car to start. These are the first two things after it wouldn't start the first time.

When you turn the key to the on position without cranking the engine over can you hear the fuel pump run in the tank for 5 seconds?

Engine Mechanical problem
2004 Jeep Cherokee 6 cyl Four Wheel Drive Automatic

Initial engine light, eventually flashing, and running like very, bad fuel. After two, independent management systerm diagonoses in two states; nobody finds a CAUSE for a # 3 misfire. Mileage is +/- 87,000. The car never actually stalls, and never fails to start; but after driving awhile, it runs VERY ROUGH! Replaced plugs, filters, plug boots, fuel injector and sleeve, and ignition coil. After these changes, auto ran perfectly for over one month.
i am elderly woman who fears being stranded again on I-69 or elsewhere. I see some similar descriptions, for older models, on your site. And they were always referred to service shop for diagnosis. I have done that twice @ almost $1,000.
Please help. jt

did you go with cheap spark plugs and plug wires? or oem quality.

same goes for the ignition coil

and only number 3 is coming up? not a random missfire code just for 3 that is correct?

Ok will do thanks for your time

Don't know what brand plugs/wires were used, but they charged ME $4.19 each. The coil was $195.00--is that cheap?

The last service notes say:
"EEC Tests codes 203 and 303 #3 cylinder misfire. Recheck plugs and coil assy installed previouslyl.
Swapped #2 and #3 plugs; and misfiire stays in #3. Check online NAPAFIX hotline. Several possibilities."
No fix.
jt

Ok tested coil pack. Is it possible the whole rail went bad?

that p0203 code was extremely HELPFUL! that is a code for a a circuit malfunction with the fuel injector on that cylinder. so we know its fuel related now. If you WANT you can take a noid light they are relativly cheap and hook up in #3 connector for injector and crank car. light should flash. put in a diff cylinder to compare it. flashing should be the same. so do you have the pulse? if not its going to be wire related to the injector. and your going to have to check for +12v on one side key on. if thats there and a voltage drop test is performed and the voltage drop is within specs power wire is good and then your going to have to start looking at groudn wire then computer.

2004 Jeep Grand Cheorkee SE.
When I try to start the vehicle, absolutely nothing happens. The engine does not even begin to turn over. However, if I sit and try to start the vehicle multiple times(minimum 20 times), it eventually starts in the manner in which it should.
The weird symptom that may give some indication as to what the problem is what the gauges are doing prior to attempting to start the vehicle. The gauges will spike up to about 25% (ie, 30-40 mph on the speedomoter) and then immediately go back down. All gauges do this and are in sepuence.
The only other note is that while the vehicle is in this "no start" mode,...is that all electrical functions do not work. Radio, door locks, windows, etc all do not function.
The vehicle has done this to me 3 times, but on all occasions has eventually started up with persistance. However, I would like to fix this asap.
Thanks in advance.

sounds like either a relay problem or something to do with the alternator. but what you can do is once you get it started go to your nearest autozone or other car parts store chain and have it put on the scan tool for free. and you should get your trouble codes and get back to me

Wow...thanks for the quick response. Ok...I will do that. Thanks again.

Drove the jeep to work acted fine check engine light was on. Went to lucnch light was still on, went back to work the parked it. Came back out after work it would not start. I can hear the fuel pump turn on and the engine cranks but will not turn over. So far ive replaced the spark plugs because the were way overdue any suggestions

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis,finding out what's going on.

Started doing my own trouble shooting Read up on a couple of Forms then i checked the basics Made sure i had fuel in the fuel bar which i did then i did a spark check by shoving a screwdriver in my coil pack and having a buddy turn the key felt no shock found out that the Crank Postion Sensor controlled voltage to it so i replaced the CPS and vola it works now

It crank but it won't start and all gages are down

Check for injector pulse, if none replace crankshaft sensor, if it has a pulse, check fuel pressure. Thanks for using 2CarPros
