2012 Nissan Altima Car Won’t Start

2012 Altima Starting Problems

Introduction Purchased a 2012 Altima recently, and encountered a frustrating issue where the car wouldn’t start despite efforts to replace the battery and starter. Seeking advice from the community, especially regarding the peculiar steering wheel behavior.

Electrical Power Delivery Issues If you’re experiencing a situation where your 2012 Nissan Altima won’t start, the problem may lie in delivering electrical power to the starter. This can be attributed to various factors such as wiring, fuses, relays, or corroded connections. Start by checking the continuity at the 250A fusible link connecting the battery to the starter. If this link is damaged, the relays click, but there’s no connection from the motor to the battery.

Dash Lights On, But No Start For those with a 2012 Nissan Altima Coupe using push-start technology, facing a scenario where the dash lights come on but the engine won’t start is not uncommon. This issue, possibly related to a faulty brake switch, manifests as a quick clicking noise and a stiff pedal. Research suggests a potential need for a new brake switch, but it’s advisable to check the current switch’s condition first.

Nissan Altima Won’t Start – Causes and Solutions

Introduction Nissan Altima, a reliable road companion, occasionally faces breakdowns due to interconnected parts. This article explores common causes of Altima starting problems and offers solutions.

Common Causes and Solutions

1. Weak Battery When your Altima’s engine cranks slowly or not at all, a weak or dead 12v battery is likely the culprit. It’s advisable to test the battery voltage using a multimeter and perform a jump start if needed. New batteries may take time to reach full capacity.

2. Corrosion on Battery Corrosion on battery contacts can disrupt current flow, affecting the starting process. Regular inspection is crucial, and if corrosion is present, cleaning the terminals can resolve the issue.

3. Weak Key Fob Battery For push-start models, a weak key fob battery may cause starting problems. The key fob, though, only signals for locking/unlocking. Placing the key fob close to the start/stop button might help start the vehicle. Trying a second key can also rule out key-specific issues.

4. Broken Starter Motor A clicking sound when turning the key indicates a potential issue with the starter motor. While a temporary fix involves hitting the starter motor, a permanent solution may require replacing the starter.

5. Defective Alternator A failed alternator can lead to a drained battery, even if a new battery is installed. While alternators are durable, they can break down, necessitating replacement.

6. Clogged Fuel Filter Over time, a clogged fuel filter can impact engine performance or prevent it from starting. Cleaning isn’t an option; the filter must be replaced.

7. Fuel Pump Failure A malfunctioning fuel pump can result in starting difficulties. Early signs include intermittent engine breakdowns and reduced performance. Replacement is necessary if the pump is faulty.

8. Blown Fuse In rare cases, a blown fuse might be the culprit. Careful examination of essential fuses is required, but handling fuses should be done by professionals.

9. Defective Spark Plugs Non-functional spark plugs can prevent the engine from starting. Loose connections may be fixable, but a failed plug requires replacement by professionals.

10. Rodent Damage Rodent damage, though rare, can lead to various system failures. Inspecting the engine compartment for signs of rodent bites is recommended, and repairs should be conducted by professionals.
