#924 of 1888 oil pressure gauge
Jun 12, 2007 (12:57 pm)
hi... i have a 2000 jeep wrangler. my problem is that the oil pressure gauge basically drops down to zero when the engine is idol. before its warm the gauge acts fairly normal but when warm it only goes up a little above zero until i'm idol then it plunges and the check gauges light comes on. this is obviously a pressure problem but the jeep seems to run fine and its been going on for more than a year. i'm just worried it's gonna crap out without warning. has anyone heard of this problem and have any solutions before i take it somewhere. thanks.

If your oil pressure was really that low your engine would have seized by now. Most likely you have a faulty oil pressure sensor.
However, as you've continued to run your Jeep when it was indicating a terminal problem, is there really much point in fixing the gauge issue? Having an accurate gauge is only useful if you're going to take notice of it.

#927 of 1888 Jeep Won't Start
Jun 13, 2007 (12:09 pm)
I post a problem concerning the Catalytic Converter. At the time money was a bit tight and couldn't afford the shop. Now I have the money but the jeep won't start to get the jeep to the shop. Its been sitting for 3 months and boy those 3 months added more problems. The jeep won't start at all!! Charged the battery, nothing. Put in a working battery from a different car, nothing. Check the fuses, ok. Took a spark plug loose to see a spark, which I don't. Could it be the fuel pump? If, so, how can I actually tell its the fuel pump? Can it be the gas filter? I'm thinking maybe its the module? Any ideas would be appreciated!! Thanks for the input.

You say that the jeep will not start.
Does the starter engage and spin the crank?
You also are wondering if it is the fuel pump.
Are you getting fuel at the injectors?
If you have no spark that is where I would start.
Do you really not have spark or can you just not see it.
If you are trying to look at spark in the daylight it's pretty hard to see.
If you have a friend dumb enough have him hold the spark plug while you crank the engine over.
Have a cold beer handy because if you are getting spark you will need a peace offering.
It is also a good thing to be faster or bigger than this x-friend.
Just as a guess I think the most likely problem starting up one of these fine JEEPs after a 3 month hibernation would be the fuel.
I would try priming the vehicle.
Try pouring a little fuel down the throat and crank the engine over.
If it starts then a lack of fuel is the problem.
You might have to do this several times.
Remember gasoline is dangerous.
Use only a little and use common sense.
It can hurt you as bad as a friend that you just subjected to electrical shock.

Go for the simple solutions. It's been sitting 3 months. What can happen in 3 months of storage?
Dead battery? Checked
Does it turn over?
Spark? No? Check the wiring from the battery. Rodents sometimes eat through or if your battery had issues, the acid could eat through em. Trust me on this one.
Do you have gas? If so, how much was in there? Check the schrader valve on the driver side and see how much gas, if any comes out.
But it sounds more electrical than anything. With no spark, I'd suspect: Battery, wires, distributor, starter. If your Jeep as a distributor, open it up and check for broken parts in the cap.
#931 of 1888 bad gas mpg on Jeep Wrangler

I have a Jeep 2004 Wrangler Unlimited, 4.0 engine,

genuine gas hog
So what mpg are you getting? How are you calculating it, and have you checked the accuracy of your odometer?
Best mileage will be obtained by a combination of vehicle condition and driving technique.
Clean air filter, clean and correctly gapped plugs, properly inflated tires, brakes that aren't dragging, synthetic lubricants, etc., etc.
Aftermarket accessories like bumpers, tire carriers, winches, roof racks etc., all contribute to poorer mpg through added weight and wind resistance.
You don't have to drive slowly everywhere, but heavy braking and acceleration will hurt. Good driving technique includes anticipating traffic and stop lights. Keep rolling at all costs, and keep top speed below 60mph. Use A/C and electrical accessories sparingly.
So again, what mpg makes you consider your '02 a gas hog?

I think the the 06's only came with a 12 month, 12K warranty since it was the last year of the TJ.
