Why Your Car Won’t Start

A no-start condition can be caused by a wide range of issues. Understanding the most common culprits helps you know what to expect when you bring your vehicle in:

Battery problems – Weak, drained, or corroded batteries are the most common cause of a dead car.
Starter issues – A faulty starter motor may click but won’t turn the engine over.
Alternator failure – If your alternator can’t recharge the battery, your car eventually won’t start.
Ignition switch failure – Electrical issues in the ignition system can prevent your car from cranking.
Fuel system problems – Bad fuel pumps, clogged fuel filters, or injectors can leave your car without fuel delivery.
Engine timing or mechanical issues – Serious internal engine problems may also cause a no-start condition.

Because there are so many potential causes, professional no-start diagnostics are the best way to get to the root of the problem.

FAQs About No-Start Diagnostics in Fairfax, VA

Why won’t my car start but the lights work?
This often points to a starter or ignition system issue. Professional car diagnostic testing can confirm the cause.

What should I do if my car won’t start?
First, check for obvious issues like loose cables. If your car won’t start after a jump-start or still cranks slowly, bring it in for diagnostics.

Why does my battery keep dying?
A failing alternator, parasitic electrical drain, or old battery may be to blame. A diagnostic test can identify which one.

How do I know if it’s my alternator or battery?
If your car dies shortly after starting or won’t hold a charge, it may be the alternator. If it struggles to crank but runs fine once started, the battery may be the issue.

Can a bad fuel pump cause a no-start condition?
Yes. If the fuel pump isn’t delivering fuel, your engine won’t run. Testing fuel pressure helps confirm this.

Is it safe to drive with a weak battery?
Not for long. A weak battery often leads to a dead car that won’t restart once turned off.

How much does no-start diagnostics cost?
It depends on the problem, but our team provides upfront pricing before repairs.

Do you service hybrid and European vehicles?
Yes. Our tools and expertise allow us to diagnose all types of vehicles.

Can you fix the problem after the diagnostic test?
Absolutely. Once we identify the issue, we’ll provide repair options and complete the work with your approval.
