Car Won’t Start With Jump: 5 Most Common Reasons Why Your Jump Fails 

What could be more irritating than a car that refuses to start?  Maybe you’re busy, and to make the situation worse, your car won’t start with jump. In today’s post, Driverevolve will discuss the 5 most common reasons why your jump fails and their corresponding fixes.

Car Won’t Start With Jump: 5 Most Common Reasons 

There are several causes why your vehicle will not start after being jump-started. A few of the reasons are listed below. Many, though, are more prevalent than others.

Dead Battery

A faulty battery is the most common underlying reason for your vehicle’s running problem. The battery is the heart of your car, supplying electricity to all components and ensuring that it runs smoothly.

Your car batteries will not last permanently. Based on driving circumstances and environment, prepare to change your car batteries every 3 years. A faulty unit or an electrical short circuit will keep the batteries from charging.

If you’re unsure about your batteries, have checked them. With today’s mobile devices, the inspection service booking process only requires a couple of minutes. Experts and car parts companies will evaluate the starter and recharging mechanisms, fix, and replace your battery if needed.

A Faulty Alternator

Your vehicle battery is insufficient to satisfy all of an automobile’s electrical system’s requirements. The alternator restores electricity to the drained batteries when you start your car. Once the motor works, an alternator supplies electrical impulses to the car’s existing electrical fittings.

A defective alternator will lead to a wholly depleted or shortchanged cell, with decreased capacity and starting performance. If the cell is regularly shortchanged due to a poor or malfunctioning alternator, it will most likely drain rapidly, resulting in sulfation.

A few symptoms of a defective alternator include:

  • The gauges of your vehicle begin to behave strangely.
  • Once the alternator overheats, you sense the stench of burnt rubber or hot wires.
  • You hear a roaring noise just before the alternator cuts out.
  • Your headlamps or dashboard LEDs flicker or fade.

If your alternator is defective, consider a replacement.

Clogged Fuel Filter

All vehicles, irrespective of motor type, have filters that purify the gasoline before it enters the motor. This procedure exposes filters to particle accumulation, leading to a congested fuel filtration system. Consequently, fuel will be unable to enter the motor, resulting in engine malfunction.

Ensure that you brush your fuel filtration system accordingly to guarantee your fuel filters are clean. Most automakers suggest replacing the gasoline filter after 80,000 kilometers or 5 years.

However, most technicians consider this figure too high and advise changing or cleansing it thoroughly after 16,000 kilometers.

The following are some symptoms of a blocked fuel filter:

  • Constant idling or crackling: Your car’s engine will frequently run without issue but will halt whenever you stop. This means that enough gasoline flows through the filters when moving but degrades when the car is idling.
  • Problems with acceleration: If you want to speed up, but your car’s velocity does not change, you must replace your gasoline filter.
  • Engine misfires or poor performance.
  • The emissions of the car release an unpleasant stench.

If one of these symptoms happens, contact an expert to clean or replace your gas filters.

Faulty Ignition Switch

The ignition switch, one of the essential electrical parts available in most vehicles and cars, is typically located behind the ignition lock piston on the steering shaft. These 2 elements function in tandem to fuel and start your vehicle.

If your batteries are in perfect health, but your vehicle won’t start after a few attempts, you might have an issue with the ignition switch. Switching on your headlamps might help you shortlist the underlying cause of the problem.

As the battery powers the display and headlamps, if they are switched on but the vehicle does not run, the potential issue may be a defective ignition switch.

If you see any of the symptoms of a faulty ignition switch, contact an expert to help you put your automobile back in top condition.

Gas Tank Is Empty

Starting your automobile on a depleted petrol tank is not advisable since there is nothing to lube your petrol pump.

In addition, your engine may suck air into the petrol pump with the last gasoline, prohibiting your car from running as this air-fuel combination makes your engine out of whack.

Experts recommend maintaining your petrol tank at least 1⁄4 filled at all times. Supposedly, doing that will help put you out of risky scenarios when you’re short of fuel and far from a petrol station.

FAQs

How Long Does It Take To Jump A Car? 

Jumpstarting your vehicle should only require a couple of minutes once you’ve plugged your wires. In most situations, 5 mins are allotted, and in severe cases, 30 mins. You must run the car for at least 15 mins after restarting the vehicle to recharge the batteries completely.

Car Won’t Jump-start, But Lights Come On: What’s The Matter? 

If your headlamps work, but your vehicle won’t run, it suggests your battery is recharged, but your starter/ignition is defective. 

Car Won’t Start With Jumper Cables Connected: What Should I Do? 

Recharge your batteries and cleanse the access points and cable connections to guarantee a proper connection. If your automobile does not run after being jump-started, consider whether your starter, alternator, or any part in your electrical circuit is defective or not.

How Come When I Try To Jump My Car, It Just Clicks?

A malfunctioning starter engine, starter relay/solenoid, or any electrical malfunction is frequently the culprit behind one loud click while starting (even after attempting to jump-start the car).

Can You Jumpstart A Car With A Bad Alternator? 

Yes.

You can jumpstart your vehicle with a poor alternator if you possess a decent battery. The car will continue to work for a while regardless of how faulty the alternator is. This is because if the alternator fails and does not provide the needed voltage, the vehicle can operate only on the battery.

Wrapping Up 

Hopefully, with the listed 5 most common reasons underlying your jump failures, you can now understand why your car won’t start with jump. However, it’s still advisable that you get your vehicles checked at a reliable auto repair shop and not conduct any risky fixes.
