Question about 2001 Jeep Wrangler

3 Answers

4.0. What caused it to shut off at 65 mph?

Now it will crank, but won't fire. The TV cable is extremely loose. Could this be the cause?

    Read this about the P0500 code. It has its own issues, but no start is not one of them.

Cranks and will not start
sure
http://jeepdied.com/no-start.html

no not TV.
got spark?
no starts have 50 causes.
best is to DIGANOSIS.
i can recommend good books on topic, they are expensive, have them all. ($100 a pop)
but $15 books don't have these skill sets articulated.
ASE books do, too. Great books. login and read.?

TV cables are set loose, !!!
on purpose, but you never said how loose is loose.
most are set with 1/2' (10mm) play,
so that there is no chance of getting dangerous fast idle speeds, and jeep getting fined, $1.2 billion like toyota for this condition.

it must be loose.
if trans TV was too loose(OVER SPEC)?
then the TRANS will shift later.
and has nothing to do with no starts ever .

but if the TV itself was stuck open 100% or near
this activates, UNFLOOD mode, killing all injection. (the throttle body internal TV)
I program ECU's so know the ecu inner workings.
but am retired. I like to help the most difficult cases., I'd so for 55 years.

Most likely not. Go to this link. They give a very good description of what can cause the no-start condition and how to methodically narrow down the options so as to save time and money.

    VEHICLE SPEED SENSOR (SPEED CONTROL

    DESCRIPTION
    The Vehicle Speed Sensor (VSS) is mounted to an
    adapter near the transmission output shaft. The sensor
    is driven through the adapter by a speedometer
    pinion gear.
    OPERATION
    The VSS is a pulse generator. The VSS pulse signal
    to the speedometer/odometer is monitored by the
    PCM speed control circuitry to determine vehicle
    speed and to maintain speed control set speed.

SOURCE: 1989 wrangler 2.5L won't turn off with new switch

Hi there:Bad installing or a problem with the connections. The most likely problem is a bad ignition switch. To find out for sure, remove the plastic covers over the steering column and remove the 2 screws holding the ignition switch in place. Make sure the mechanism coming from the key is turning the ignition switch. If the mechanism works fine, replace the ignition switch.

I would suggest removing the ignition switch and checking the mechanism in the column to make sure it is actually turning the ignition switch off.


You could have a wiring problem, you will have to follow all the wiring from the ignition switch down the column and into the harness, there is sure to be a short in the wiring harness, that is if as you said you replaced the ignition switch for a new one.

To test this, remove the plastics around the steering column and pull out the wiring plug to the ignition switch, if the ignition turns off you have another faulty ignition switch if it stays on wiring harness has shorted out.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

SOURCE: I have a 2001 Ford F-350 and when I go to start it , it doesn't fire up right away it cranks cranks cranks then fires up ? What is the causing this ?

If this is a Diesel, the glowplug timer is bad or the glowplugs are bad. For either Diesel or a Gasoline unit the fuel should be available at startup.

Slightly different problems for fuel delivery for each system but pressure can be read with proper tools to let someone diagnose this and eliminate or confirm whether the engine is fuel starved. Then repaired to solve lack of fuel pressure.

I have a 96 geo prisim 1.6 ltr 3 speed automatic, and it won't shift till 35 and then at 65 mph very hard. What could be causing the problem and What can I do to fix the problem?


There are several things that could cause this. One you could fix is the throttle cable that goes to the transmission. Called the TV cable. If it is not connected to the throttle linkage, it will cause this problem.

Car won't crank check for fuel and no fuel put gas in and check the fuses everything seams good check for power going to the fuel pump with the switch on and there is no power to the fuel pump. We


Fuel pump will only have power for 2 seconds unless engine is cranking or running. Most common cause for ur problem is a broken dowel pin in the cam gear causing the timing to be out just enough to shut itdown

What causes ignition modules to go bad in 1991 delta 88


Generally the cause of an electrical component to fail is high heat or extreme voltage load.
Is the coil pack and module getting too hot from the heat of the engine ?
Is it shorting out because of oil or wet surfaces ?
Could you be loosing voltage to the module from the key switch ?
Are you loosing ground signals from the computer ?

91 Geo Storm Gsi running just fine, one day I lost power driving 65, check engine light came on and was flickering, mph arm going up and down but didn't die then. Then it was ok.That happened 2 times...


Most engines don't fair well under extreme heat. It's apparent you might have some electrical issue's. Your rpm's or mph arm going up and down could be faulty speed sensor would cause arm problem. I think you may have more than one problem, the car shutting off is due to engine over-heating. Check cooling system-thermostat, water pump, radiator, engine fans and coolant temp sensor and fan relay's. It could be as simple as blown radiator hose.

Engine shuts down on deceleration


Well 145K is alot of miles, catera's are not that reliable especially after 100K. It sounds like you could have multiple issues but take it to a mechanic asap before it becomes unfixable.
