Troubleshooting And Fixing A Jeep That Dies While Driving But Restarts Afterwards

It’s entirely normal to feel a bit anxious when your Jeep keeps stalling and restarting frequently. The reassuring news is that, most of the time, the reasons behind it are not too serious and can be resolved with quick fixes.

Let’s delve into the common causes of this issue and explore the solutions below.

1. Issue with the crankshaft position sensor

If you check out how others deal with a similar problem in their Jeeps, many mention issues with the crankshaft position sensor.

When this sensor starts acting up, it can lead to your Jeep stalling and restarting off and on until it finally gives out. Once it’s entirely kaput, there’s no spark at the distributor, and your Jeep won’t start. Many people have shared their experiences with crankshaft sensor problems, often without any error codes.

The Jeep Wrangler JK and Sahara seem to get the most complaints about the crankshaft sensor. The good news is that replacing the crankshaft position sensor is quite straightforward.

While aftermarket sensors are usually not too pricey, most experts suggest going for the Mopar crankshaft position sensor, which might set you back around $150.

2. Inadequate fuel pressure

Those with years of Jeep experience often recommend a straightforward method for troubleshooting: measure the fuel pressure using a gauge. Low fuel pressure frequently emerges as the main troublemaker causing engine stalling.

Various components contribute to maintaining proper fuel pressure, but a frequent culprit is a malfunctioning fuel pump. It might go awry due to issues like a faulty fuel pump relay, loose terminals, malfunctioning fuel injectors, or a blown fuse.

While investigating, it’s worth giving the fuel filter a once-over. If it’s accumulated dirt, it could disrupt your Jeep’s normal functions. Sometimes, a simple solution could be changing the fuel filter

3. Faulty or corroded battery cables

The second most frequent troublemaker in this situation revolves around the battery’s connections. When the battery cables in your Jeep become loose or gather dirt over time, they can result in signal loss, causing the system to suddenly shut down.

Once the signal is back on track, your Jeep springs back to life. While it may seem like a simple hiccup, if it becomes a recurring theme, it can take a toll on your vehicle.

Many seasoned Jeep enthusiasts suggest keeping an eye on the battery’s terminals and connections. Make sure they are snugly secured and free from corrosion. If you spot dirt or rust, take them out and give them a thorough cleaning.

4. Connection problems and vacuum leaks

At times, cables and wires decide to play it loose, overheat, or get all corroded. Any of these shenanigans can lead to the engine deciding to take a break.

Take, for instance, a user who shared dealing with a misbehaving wire from the alternator to the battery. This little troublemaker caused the engine to throw a fit and then reboot. Despite trying to swap out other parts, it turned out that a simple wire replacement was the real hero in the end.

While it’s nearly impossible to play detective while cruising, trying to figure out if there’s a wiring or connection hiccup, you can give them a once-over later to see if that does the trick.

Now, if the spark plugs or the ignition switch in your Jeep are feeling a bit lazy, they too can throw a party and shut down the engine.

Another common party crasher is vacuum leaks. It’s not a good idea to keep cruising around if your Jeep is leaking. If you catch any vacuum leaks, it’s wise to get them sorted out pronto.

5. Bad battery or alternator

The sweet spot for a Jeep battery’s lifespan is usually 3 to 5 years, but that depends a lot on how often you use it and how well you take care of it. If your Jeep is your trusty sidekick on many adventures, the battery might wave the white flag earlier than expected.

Now, here’s the plot twist – a bad alternator can join the scene. If the alternator decides to throw in the towel, it can play the Grim Reaper for your battery, leading to the engine giving up the ghost.

Keep in mind that the battery temperature sensor could also be the culprit. If your battery or any of its buddies start feeling the heat, it can trigger the battery temperature sensor to pull the plug on the engine. Swapping out the problematic battery could be the key to putting this issue to rest.

6. Inoperative throttle body or throttle position sensor

A wonky throttle body or a misbehaving throttle position sensor might be the mischief-makers. Surprisingly, just giving the throttle body a good cleaning seemed to do the trick for many.

If that doesn’t sort out the hiccup, it’s detective time—test the throttle position sensor. A faulty sensor can play a prank on your Jeep, making it stall and then act like nothing happened, starting right back up. The good news? You can swap out the sensor yourself. While you’re at it, give the idle screw a once-over and tweak it as needed.

7. Defective ECU

A glitchy Engine Control Unit (ECU) is a frequent headache, especially for the older members of the Jeep family. When the ECU decides to throw a tantrum, it can play the disruptor during the ignition process, abruptly causing the engine to take a break.

And just like that, when it decides to behave again, the engine springs back to life.

The ECU, being the brains of the operation, can also get a bit overheated and stir up trouble. Detecting occasional hiccups in the ECU can be like finding a needle in a haystack.

If you’re scratching your head and can’t pinpoint the issue, the ECU might be the mischief-maker. It’s wise to call in an expert to diagnose and work their magic.

Should you keep driving if your Jeep dies but restart?

Driving a Jeep that keeps stalling and restarting is not the safest bet. However, whether you should continue driving depends on your specific situation.

While the issue may not come with significant risk factors, picture yourself stuck in the middle of the road, unable to kick your Jeep back into action! It’s a scenario best avoided. So, it’s crucial to address the problem pronto to steer clear of getting stranded without a helping hand.

There’s also the potential danger of your Jeep deciding to take a break on busy roads. If it decides to stall at the wrong moment, it can pose a life-threatening situation for you and others on the road.

If, for some reason, you must use your Jeep in this state until you can fix it, try to limit your trips to short distances.

Avoid bustling roads with heavy traffic, stick to the right side, and flick on those emergency lights for added safety.
