What causes a Jeep Wrangler Sport not to start without using starter fluid when it runs fine after starting?

In order to determine the problem, we will need more information about your vehicle. Information such as the year, make, and model, would be helpful. However, as a general answer, here are my remarks: A vehicle that is fuel injected, either with a TBI (Throttle Body Injection) or PFI (Port Fuel Injection), relies on several sensors to determine how much fuel needs to be supplied to the engine in order to start. Two very important sensors in particular are the coolant temperature sensor and the air temperature sensor. If a sensor sends a 'warm' signal to your vehicles computer, then the computer will assume the car has been running and not inject much fuel at all. If the sensor was unplugged, then the computer would inject too much fuel. If the vehicle is carbureted, a common reason for cold start failure is the choke which is also known as a choke coil. Since there is no onboard computer to give the car more fuel in cold weather, the solution is to reduce the amount of oxygen that is supplied to the engine. When operational, the bi-metal choke relies on temperature to expand and contract. When it does this, the choke coil linkage pulls or pushes a metal plate, sometimes called a butterfly, covering the air intake of the carburetor. After time the choke coil will lose it thermostatic properties and fail to push or pull the linkage. In short, check your carbureted vehicle when cold. The butterfly over the carburetor should be closed. If your vehicle is fuel injected, you will likely need to test or replace the air and/or collant temperature sensor. -- JJohnson

What causes a starter solenoid to click but the starter doesn't turn?
It could be that there is a bad connection between the starter solenoid and the starter, or that the starter motor itself has failed. Check the wires first. They're cheaper to replace. This also happens when the battery is very low, so it may be worth charging the battery if you haven't already eliminated that possibility.
What is celinoid?
The starter solenoid receives a large electric current from the car battery and a small electric current from the ignition switch. When the ignition switch is turned on, a small electric current is sent to the starter solenoid. This causes the starter solenoid to close a pair of heavy contacts, thus relaying a large electric current to the starter motor, which in turn sets the engine in motion.
What causes a battery to have no cold cranking amps?
All the lights work the voltage is fine and I just replaced the starter. But it registers no CCAs
How a starter solenoid works?
When the car is started, voltage is sent from the battery to the solenoid. The pull-in coil is capable of drawing a lot of current and generating a large magnetic field, and is the primary drain on the battery. This creates the magnetic force that draws the plunger into the core and completes the circuit between the terminals of the battery. The movement of the plunger causes the starter's drive gear to move into mesh with the flywheel ring gear. This is what causes the motor to turn. The hold-in coil generates a much weaker magnetic field and holds the plunger in place. This saves battery power and reserves most of the battery's life for starting the car.
Starter problems when the car is hot?
No, the starter has nothing to do with the engine overheating. Possible causes are.Low of coolantThermostat stuck closedCooling fan not workingBlown head gasket (very serious, stop driving the car)Clogged radiator
What causes sluggish starting car engines?
it could be the starter motor getting lazy
What causes Blown fuses when starting a 2001 chrysler sebring?
A fuse blows when the current in the circuit passes what the fuse is rated at. If you are blowing the ECM/starter fuse, the starter is probably bad.
What causes bad starting?
A battery in poor condition, Dirty battery cable connections, Loose battery cable connections, A worn out starter,

What causes wet floorboards in Jeep Wrangler?
There are several possible causes here: A leaky windshield seal, a leaky top seal, or missing floor plugs. The most likely answer, however, is that it's a Wrangler.

Check the starter, wires to & from & connections to it & the battery.
What causes the starter not to engage periodically on a 1998 ford expedition?
starter motor need overhaul
Why do you have trouble starting the car though d battery and alternator are ok and there are no sounds to be heard upon turning the key however it works based on luck?
Starting FailuresYour question is confusing, "...based on luck?"I suspect that you mean that the problem is intermittent [sometimes it works when you turn the key to the start position, and sometimes it doesn't.IF that's the case I suspect one, or a combination, of the following:A "loose" connection somewhere in the starter/solenoid circuit,A defective starter solenoid,A defective starter,A defective starter/ignition switch.NO ONE can tell you precisely what the cause is without "troubleshooting" the entire starting system, but the above causes can result in the symptoms you describe.You need to have someone who knows what they are doing to troubleshoot your starting system, find and identify the cause(s), and make proper repairs.
