SOURCE: 1997 Jeep Grand Cherokee cranks but won't start

Same thing happened to me at about 140k. It was the fuel pump. Best way to test if your pump is failing and loosing pressure is to see if the car will start immediately after it has been running, or turn the key to the alt position for a few minutes before starting. If your engine fires faster after it has been running or the key has been in the alt position you will probably need a new fuel pump. Great news is with a very deep socket to get the tank straps off its a 30 minute job to replace the pump/filter assembly.

The egr valve is located on the front of the right cylinder head. It has a tube attached to it and going to the intake manifold.It has failed and is why your jeep is running rough and hesitating. Replace it and it will fix your driveabllity issues. Disconnect the battery for 2 min to clear the code.

SOURCE: I'm experieince intermittent starting . One day the jeep will crank & start, the next day when I attempt to start it I get nothing.

Its the starter solenoid. Remove 2 bolts and the lead wire and pull the starter out. most local parts stores can test the starter for you, but if the problem is intermittent it might not show up during their test.

On my jeep, after pulling the starter, I disassembled the solenoid. The actual failure of the solenoid was the electrical contact. I cleaned off the corrosion and have had no problems for 40,000 miles.

my guess, is you have the remote engine start option.

name what it does exactly. (wont even attempt to crank? over?)
btw, this system is a risky system.
and has many safety features to protect the public.
did you read the operators guide on this? yet?
lost it?
here it is for free, read the Remote start pages..
it shows, how to diagnose simple issues.
door lock failure? or not in park, or ?
there are many failures (simple) that can kill this feature dead.
for good cause.

My 2005 PT Cruiser shows error codes P0508, P0688, and P0522. Sometimes it runs well, and other times it runs rough then dies and won't start back.


this obd2 trouble code table can help u understand the meaning of code.
po522, the possible solution:
The most likely cause is a faulty oil pressure sensor/switch.
for p0688, you can Check all the ECM fuses, if the fuses are OK try replacing the ASD relay.

I gat 3 cods P0129, P0685 and P0688 and then cam the "enable" I don't start the engine. What is the problem? Can you help me?


P0129-This Relates to Pressure for Barometric is too Low
P0685-This Relates to Open circuit for PCM/ECM Power Relay Control
P0688-This Relates to Circuit for PCM/ECM Power Relay Sense
I am not 100% sure that these are correct as I had to go through Chrysler settings to find this model.
I would check the airflow sensor first on the ducting from air cleaner to engine.
Check the spark plugs to ensure that they haven't fouled.
I hope this helps you,or get back to me with your results for further diagnosis.

2007 JEEP GRAND CHEROKEE WON'T START , LIGHTS ON DASH AND RADIO COMES ON , BUT WON'T TURN OVER, READS TRANSMISSION HIGH TEMPERATURE , JUST BOUGHT A BRAND NEW BATTERY FOR IT


I have found the solution to this problem. I have replaced a total of 3 starter motors and has gone away for various periods of time. Further diagnosed when concern happened again starter
would work again after starter ignition feed wire wiggled. I found corrosion build up in connector at ignition feed wire. I replaced connector on wire to starter solenoid and concern has not returned.

The headlights on my 2005 grand cherokee flicker


Solution implys a diagnosis and no one can give an accurate diagnosis from the information you provided. I can however give a ist of possible tests to eliinate some possibilities. Check your battery voltage with a Digital Multimeter, next check the charging voltage, if you are unsure how to perform either of these tests check with a local autoparts store, they will try to sell you a battery so they have the equipment to check on hand. if this does not give any more information then try to clean and re connect grounds. let me know the outcome
