My Mazda2 won't start on the first try but starts on the second. What's wrong?

Short answer: First figure out if it's clicking or cranking. One click with no crank points at the battery, the starter or a worn key the immobilizer can't read, so try your spare key and get the battery and starter tested free at a parts store. If it cranks fine but only starts on the second try, check whether fuel pressure is bleeding off overnight before you buy sensors.

Symptom: You turn the key and either hear one click, or the engine cranks without catching. The second or third try starts it.

What to check first

1. Note whether it clicks or cranks. They point to different problems.
2. Try your spare key.
3. Have the battery, starter and alternator tested. Many parts stores do this for free.
4. If it cranks but won't catch, have fuel pressure checked after the car sits overnight.
5. Run your VIN at nhtsa.gov/recalls.

Likely causes

1. Weak battery or starter. A single click and no crank usually means the battery, the starter or its solenoid isn't getting or passing enough current.
2. Key not read by the immobilizer. The Mazda2 has an immobilizer, a chip in the key the car must read before it will run. A damaged key or weak signal can block the first start.
3. Fuel pressure bleeding off overnight. If it cranks normally but only catches on the second try, fuel pressure may be leaking away while parked.

What it usually costs

Battery and starter tests are often free. Owners in these threads had already paid for a battery and a fuel pump that didn't fix it, so test first.

Is it safe to keep driving?

It's not dangerous, but it can strand you. Keep the spare key handy and fix it before a trip.

DIY or shop?

Testing, trying the spare key and a battery swap are DIY. A starter or fuel pressure diagnosis may need a shop.

Recalls, bulletins and complaints in plain words

• Recalls: NHTSA lists 2 recall(s) for the Mazda Mazda2 in these years, and none match this problem. Check your VIN at nhtsa.gov/recalls. If your car is part of a recall, the dealer fixes it for free.
• Plain words: The complaint count below shows how often owners reported problems that mention these words to NHTSA. A count is not proof of a defect.

This counts complaints that mention these words. It is not a defect finding.

What owners report

• In My Mazda 2, auto 1.5, 2011 won't start in first crank, so I but starts in second crank always. on Reddit r/mazda2, a 2011 Mazda2 automatic with about 150,000 km wouldn't start on the first crank but always started on the second. A new fuel pump and filter didn't help. Replies suggested getting the battery, starter and alternator tested free at a parts store, then renting a fuel pressure gauge to check for low pressure or a leak. One reply doubted a mechanic's suggestion to replace the crank and cam sensors, since there was no check-engine light.
• In Car won’t start on first try, hear one clicking noise on Reddit r/mazda2, a Mazda2 owner heard one click and no start on the first try, but it started after two or three tries. A new battery helped for a day. Replies said to check the starter, the solenoid and the ignition switch, and to try the spare key because the immobilizer may not be reading a worn key.

Quick tip

Listen first, buy parts second. A click and a slow crank are two different problems, and knowing which you have saves you money.
