When did the cap and rotor ignition system come out on Jeep Wranglers?
All on their own or combined will make for better performance. During the early years of the Jeep TJ Wranglers, which ran from 1997-2006, the cap and rotor style ignition system would return. It wouldn’t live long into the 2000s, though.
Where are the coils on an ignition coil?
They can be located on the face of the pickup coil or on the outside of the distributor. Step 4: Replace the pickup coil: Install the new pickup coil, making sure the wire connectors and mounting screws are properly tightened. Reinstall the ignition rotor, distributor cap, and plug/coil wires. Note: Follow steps 1-3 from Method 1 first.
How do you replace an ignition pickup coil?
Step 1: Disconnect the battery: Remove the negative terminal on the battery. Step 2: Remove the distributor cap and rotor. Step 3: Remove the ignition pickup coil: Disconnect the electrical wires to the pickup. Step 4: Replace the pickup coil: Install the new pickup coil, making sure the wire connectors and mounting screws are properly tightened.
Can you upgrade ignition system on Jeep Wrangler?
Upgrading the ignition system is incredibly simple. The first and cheapest thing you can do is upgrade the spark plugs. Moving up the list you can swap in an aftermarket ignition coil. For the really brave you can swap out the distributor itself. The reason you would want to do any of this is to get a hotter spark to the cylinder faster.

Where are the pickup coils located on a car?
They are located inside the distributor and function as the trigger for the ignition system to produce spark. The pickup coil monitors the rotation of the distributor and triggers the ignition system at the optimal moment to produce the best timed spark for best engine performance.
Why was the ignition system of a Jeep Wrangler so bad?
The ignition system had its flaws due to its mechanical nature—especially because it was dialed in by the human hand. Understand that many things can affect how the engine runs and what it needs in order to run well. The time of the ignition would be something subjected to adjustment in order to run right.
What is the ECM on a Jeep Wrangler?
But we all know appearance isn’t everything. The TJ’s coil packs return, but the distributor itself fades into Jeep lore. Instead, the distributor is replaced by position sensors that are linked to the Engine Control Unit (ECU), sometimes called an Electronic Control Module (ECM), which can also be upgraded for additional performance.
What is the ECU on a Jeep Wrangler?
Instead, the distributor is replaced by position sensors that are linked to the Engine Control Unit (ECU), sometimes called an Electronic Control Module (ECM), which can also be upgraded for additional performance. This ECU dictates when spark signal is needed.
When do you change the firing order on a Jeep Wrangler?
Though the firing order will never change, spark may be needed just before or after the piston reaches the top dead center (TDC). The TJ’s gear-driven system keeps this firing sequence well fixed, whereas the new JK’s fuel and spark maps allow this sequence to change at any given time.
Where is the distributor on a Jeep Wrangler?
If you were to take a peek under the hood of your YJ Wrangler, you’d be sure to find one of these contraptions buried under the ignition wires. To better understand a distributor, and how it works, let’s briefly talk about the basics. A distributor is a mechanical device that utilizes the engine’s camshaft for operation.

Where does the firing order start on a spark plug?
The firing order starts at the distributor’s number one terminal and continues in clockwise or counterclockwise fashion until reaching the number one terminal again. If the manual gives the firing order as 1, 3, 2, 4 and the rotor moves clockwise, connect cylinder three to the distributor terminal immediately clockwise…

When do you need a spark in a Jeep Wrangler?
The previous gear-driven TJ ignition system dictates when a spark is needed based on camshaft position—a situation that can present issues for optimal ignition timing. Though the firing order will never change, spark may be needed just before or after the piston reaches the top dead center (TDC).
Where are the gears located on a Jeep Wrangler?
As the gear on the camshaft spins, it drives the gear located at the bottom of the shaft on the distributor. This turns a rotor within the system that drags contact points along one another within the distributor cap.
What makes the ignition system on a Jeep Wrangler different?
Though modern Jeep Wrangler ignition systems have much in common with their predecessors, a few things separate each system from each other. Let’s explore each generation’s ignition system, focusing on the differences to help you understand what makes your Jeep Wrangler’s ignition system different from the others.

Is the YJ ignition the same as the JK ignition?
With the advancements in technology and today’s standards, the gap is large between the JK’s and YJ’s ignition system. Though they share the same principles, they wouldn’t even look remotely similar. Coil packs would return for this year, but the distributor itself has faded off into the sunset as a relic of the past.
What’s the problem with the ignition on a Jeep Wrangler?
A Wrangler part to pay special attention to is the ignition switch. The majority of ignition switch complaints for second generation Wranglers are because of age, but you’ll find malfunctioning ignition switches in the third generation, too. The ignition switch is not the slot you push the key into — that’s the lock cylinder.
Where is the ignition switch on a Jeep Wrangler?
The ignition switch is usually found behind the lock cylinder, and it has three central functions: Accessory power: This is the result of turning the key to the first position, which allows you to roll down the windows, turn on the radio and use other electrical accessories.
Are there any problems with my 1987 Jeep Wrangler?
Leaking in the A-pillar is well-known among 1987 Jeep Wrangler issues, and it remains a concern for the other generations. Door leakage is especially common among 2002 Jeep Wrangler problems. Poorly sealed doors create a damp environment that may cause unpleasant odors. If the issue gets bad enough, the moisture might damage electrical systems.
