i would also change the fuel pressure regulator on the fuel rail could be allowing to much pressure on the fuel rail
Good luck to the rest of you out there.
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.
good luck
With all the troubles its had I have changed every sensor in this thing.. plus the coil.. cap... rotor.. wires..the PCM...breakers,,hoses..lines.. etc. We have checked the fuel flow coming from the pump and it seems to be a good stream. But I havent pressure tested it. But I am wondering if the fuel pump is starting to get old and breaking down under a load and causing this problem.
Any help would be appreciated.
It Pi$$es me when it runs like crap. but.. when it runs ok.. its a sweet little ride.
"Jerk Every Electrical Part.. Gobbles Cash. "
Thats worth every penny and then some !!
Any Ideas???
Thanks!
Now I am not sure what I am looking at could it be the starter or :confuse: to me it sounds like the starter is engaging but there is nothing for it turn can the teeth be wearing on the starter or what its engaging with. Is it going to be a big job
Its a 2003 model with only 60,000 miles
All help is appreciated.
Thanks,

The symptoms you are experiencing sound very much like the ones on my JGC. The mechanic found the weak battery when trying to diagnose the problem. The battery died as he was trying to start it. He suggested replacing the battery (which I did) but his diagnosis was a vacuum leak in the intake manifold. As I didn't have the money to have the intake manifold pulled and the gaskets replaced at the time, we agreed that I would drive it until I could afford the work. But you know, I haven't had a problem since the battery was replaced. Strange, but when you realize that you are driving a computer on wheels, it sort of makes sense.

when i turned the key on position the volt instrument cluster show at 9volts and the check gauges lamp is on,the driver seat
stop to go front and back the only thing that work on the driver seat is the pump on the back, (when i tern the key to the stop
possition after for 10 minute 0r 15 the driver seat work again.),
the passenger seat work ok, but both dosent have heat,when i press the heat buttons the light is on the buttons but the heater
of both seats do not work.
when i turn the key to the start possition the Jeep start but when i press the gas the mashine not work normal make convulsion(spasm)
(broum broum).I think maybe the problem was the battary is not full and i went slow slow for a small drive,after for one killometer
the mashine stop to work with out to press the gas.After i check with voltmetter the battery,i realised that was overcharging from
the generator (was 15volt and when i press the gas the volt make up 16-17v).i thing that the problem was the generator,then
i chaing the generator and the battery but the same problem.i check all the fuses is ok! i check also the connecions to the power
train control module and all the others.
With your experience can you please tell me if i can check somthing else
thank
Hope this helps.

If you haven't yet figured out the problem, answer these questions and then we can go from there. By the way, instead of buying a code reader that will only read and clear trouble codes, go to Auto Zone or Advance Auto Parts and they'll scan your truck for trouble codes for free. Write down what the reader says for future reference. After you do all of this, post what you find out and maybe some of us can help. Let me know if you have any questions.
After all that I checked from the original post here, I finally gave in and bought an Optima red top battery from Costco. Cost about $130.00 but seems to be working now and the 2 day battery drain is gone. I had a Walmart battery that I replaced 3 times before going to the Optima. Seems to have fixed it. Hope this helps for others that have the same problem.
