Pulsar 150 BS6 Not Starting: Fixes Riders Miss Often

Riding my bike through Denver taught me that cold air and fuel injectors are a tricky mix. One icy morning, my own ride just would not fire up before work. Dealing with a pulsar 150 bs6 not starting is a stress I know well. I have fixed these bikes for years and found the best shortcuts. Let me help you get back on the road with these simple steps.

Why Your Pulsar 150 BS6 Suddenly Refuses to Start

It is early morning. You have your office shoes on and your helmet is strapped. You press the starter button, but the bike stays silent. My heart used to sink when this happened to me. These new fuel-injected bikes act much differently than the old ones. A small spark of panic is normal, but we can fix this. I will show you how to check your bike step by step.

BS6 Pulsar Starting System Basics (Quick Context)

The BS6 model brought big changes to your ride. The old parts are gone, and new tech is in charge now.

What changed in BS6 Pulsar 150

• Fuel Injection (FI): This replaces the old carburetor for better flow.
• ECU Control: A computer brain now runs the spark and fuel.
• Battery Power: Your battery health is now the most vital part.

Why old Pulsar tricks don’t always work

• There is no choke lever to pull on cold days.
• The kick-start is gone, so you rely on the electric start.
• The ECU will block the engine if it senses a small error.

First Checks Before You Touch Any Tools

Start with the fastest wins first. These take no skill and often solve the issue in seconds.

Kill switch, side stand, and clutch sensor

• Kill Switch: Check if it is half-pressed. This is very common.
• Side Stand: The sensor will cut the power if the stand is down in gear.
• Clutch: Make sure you pull it in all the way. A loose sensor here means a silent bike.

Ignition key and dashboard behavior

• Ensure the handle lock is fully released so the key can turn.
• Listen for the fuel pump buzz when you turn the key to “On.”
• If dash lights flicker and then fade, your power link is weak.

Battery Issues: The Biggest BS6 Pulsar Problem

Modern FI bikes demand a very strong battery to run the pump and the brain.

Signs your battery is weak

• The starter clicks but the engine will not crank over.
• The fuel pump primes very slowly or makes no sound at all.
• The bike starts once but dies at the very next stop sign.

Why Pulsar 150 BS6 batteries drain fast

• Short city rides do not give the stator time to charge the cells.
• Using USB chargers or phone mounts adds extra load.
• Leaving the bike unused for just a few days can drain a weak battery.

What you can safely do at home

• Check that the terminal bolts are tight and snug.
• Look for white powder (corrosion) on the metal bits.
• Use a simple tool to test the voltage if you have one.

Engine Cranks But Doesn’t Start

This is very frustrating. The engine turns, but it just won’t fire up.

Fuel injection problems

• A fuel pump relay might fail and stop the gas flow.
• Bad fuel can clog the tiny injector hole.
• If you don’t hear a prime sound, the pump is not getting power.

Spark and ignition issues

• A worn spark plug cannot light the fuel air mix.
• The ignition coil can get weak when it gets hot or wet.
• If you smell gas but hear no fire, the spark is missing.

Completely Dead: No Crank, No Sound

Silence feels much worse than a cough. It means the electric path is broken.

Starter relay and motor

• If you hear a single “click,” the relay is trying but the motor is stuck.
• Sometimes the motor works when hot but fails on a cold morning.
• Overheating in heavy traffic can cause the starter to stall.

Fuse box and wiring faults

• Check the main fuse near the battery tray.
• Look for a loose ground wire that might be shaking.
• If you smell burnt wires, stop testing and turn the key off.

Sensors and ECU Confusion (BS6-Specific)

Modern problems need modern thinking. Sensors now tell the bike when to run.

Sensors that block starting

• Side Stand Sensor: A bit of mud can make it think the stand is down.
• Crank Position Sensor: If this fails, the brain does not know the engine is turning.
• Throttle Sensor: If this is confused, the fuel mix will be wrong.

Weather, Roads, and Timing Matter

The context of the fail tells half the story.

• Cold Mornings: Thick oil makes it hard for a weak battery to crank.
• Rainy Evenings: Water can get into wire plugs and cause shorts.
• Hot Rides: Heat can cause “vapor lock” in some fuel lines. I once had a bike restart near a tea stall after it cooled for ten minutes.

Why BS6 Pulsars Hate Low Fuel

The fuel gauge can lie to you sometimes.

• The fuel pump needs gas to stay cool and keep pressure high.
• Reserve fuel is not like the old days; the pump needs a certain level.
• The bike may stall even if the dash shows “one bar” left.

Safe DIY Checks You Can Try

Use your senses before you reach for a spanner.

• Listen: Do you hear the fuel pump buzz and the relay click?
• Look: Check for loose wire plugs or fuel leaks.
• Smell: Sniff for raw gas or burning plastic.
• Feel: Touch the relay to see if it feels too warm.

When to Stop and Visit the Service Center

Knowing your limits builds trust with your bike.

• If the bike has repeated no-start issues every week.
• If the Check Engine Light stays on while you ride.
• If the injector needs a pro cleaning.
• If you need a tool to read the ECU error codes.

How to Explain the Problem Clearly to the Mechanic

This saves you time and money. Tell the pro:

• The exact time and weather when it failed.
• If you heard a click, a buzz, or just total silence.
• The fuel level and if you just added an accessory.

Preventing Future Pulsar 150 BS6 Starting Issues

Small habits make a big difference for your ride.

• Start the bike at least once a week if you do not ride.
• Plan to replace the battery every two or three years.
• Only use high-quality fuel from a trusted pump.
• Keep your wire plugs clean and dry after a wash.

Tools Worth Keeping Handy

You don’t need a shop. Just keep these few things.

• A basic multimeter to check the battery.
• A spark plug wrench for quick cleans.
• A small roll of electrical tape.
• An emergency help number saved in your phone.

Final Recommendation

Fixing a pulsar 150 bs6 not starting is usually about power or a simple sensor. In my experience, a tight battery bolt fixes many “dead” bikes. Stay calm and check the kill switch first. You will be back on the road in no time.
