Fuel Pump Removal and Installation Guide for Perodua Alza 2010

There are several steps you can follow to make removing the existing fuel pump safer and easier before installing a new one.

Step 1: Relieve Fuel Pressure (Important Safety Step)

First, remove the EFI fuel fuse to stop the fuel pump from operating and to prevent pressure buildup in the fuel hose.
Then, crank the engine 1–2 times to release any remaining fuel pressure inside the hose.

This step is important because it helps prevent fuel from spraying out when you disconnect the fuel lines later.

---

Step 2: Access the Fuel Pump

The fuel pump is located underneath the rear left passenger seat.

1. Remove the left rear seat.

2. Unscrew the seatbelt bolt on the left passenger side.

3. Slightly lift the rear seat to detach the carpet from the seat clips.

4. Pull the carpet aside to expose the fuel pump access panel.

Tools Required

• 14mm socket spanner (or impact wrench) – for seat bolts

• 17mm socket spanner (or impact wrench) – for seatbelt bolt

• 6mm socket or Phillips screwdriver – for fuel pump screws/bolts

Extra Tip

Using an impact wrench can significantly speed up the process, especially when dealing with tight or old bolts.

Old Perodua Alza 2010 - Check Engine Light, No Power, and Difficulty to Start Engine

🚗 When Your Perodua Alza Loses Power… It Might Not Be What You Think

Have you ever experienced your Perodua Alza 2010 suddenly showing the check engine light, losing power when accelerating, and becoming difficult to start after shutting it off?

😓 It’s a frustrating situation — and your mind immediately starts racing.

You might assume that something serious has failed, and begin suspecting parts like:

🔧 Crankshaft Position Sensor
🔧 Camshaft Position Sensor
🔧 Fuel Injectors
🔧 Spark Plugs
🔧 Ignition Coils
🔧 Fuel Pump
🔧 Relays
🔧 IAC (Idle Air Control Valve)

So you start checking… and checking… and checking.

⏳ Hours go by. Maybe even days.

But everything seems fine.

At this point, you might convince yourself:
“Something must be faulty… I just haven’t found it yet.”

And that’s when costly replacements start becoming very tempting.

💡 The Unexpected Discovery

I learned this the hard way.

After spending days troubleshooting and overthinking the issue, the real cause turned out to be something incredibly simple:

👉 A clogged fuel pump filter

Yes — that’s it.

No expensive sensors.
No major component failure.
Just a blockage affecting fuel flow.

---

🧪 How I Found Out (Without Opening Anything)

Here’s the interesting part.

I didn’t even remove the fuel pump to inspect it.

Instead, I tried a simple and affordable solution:

🛢️ Mr. DIY Aeropak Petrol Fuel System Cleaner

After pouring it into the fuel tank, something amazing happened:

✅ Check engine light disappeared
✅ Engine power returned
✅ Car started normally again

And the best part?

💰 It only cost around RM7.00

---

🤯 The Lesson Learned

Sometimes, we tend to:

❌ Overthink the problem
❌ Assume the worst-case scenario
❌ Spend time and money replacing parts blindly

When in reality, the issue might be something small and easily fixable.

It’s honestly frustrating to realize that after all the effort, the solution was so simple… and so cheap.

---

✅ Final Advice

Next time you experience:

⚠️ Check engine light
⚠️ Loss of power
⚠️ Difficulty starting

Before jumping into expensive repairs…

👉 Try a simple fuel system cleaner first.

It might just save you:

💸 Money
⏱️ Time
😵 Stress

Sometimes, the smallest fix makes the biggest difference.

MotoLube 5w50 Engine Oil Review After First Time Use

🚗 First Time Trying MotoLube 5W30 – Surprisingly Impressive!

So I recently tried MotoLube 5W30 brewed by Yokohama Malaysia, and let me tell you—this budget-friendly oil took me by surprise.

🔧 The Discovery

I picked up a bottle from SK Hardware 6th Mile Kuching for only RM98—yes, only RM98! At first, I wasn’t expecting much. I’ve been using Perodua’s standard engine oil on my old Alza for quite some time. It gets the job done, but never really impressed me.

⚙️ The First Drive

After the oil change, I immediately felt the difference. The engine felt noticeably lighter, almost identical to how it feels with Shell Helix HX7 5W30. Throttle response improved, and it even felt like I gained a bit more torque. For a car like mine, that’s a big deal.

💡 Performance vs. Price

Based on experience, MotoLube performed nearly on par with Shell Helix HX7. What shocked me was that it outperformed Perodua’s own engine oil, and yet cost less—at least at the time. And here’s the kicker:

Fuel consumption dropped from 12L/100km to 9.9L/100km.
That’s a huge win in terms of fuel economy for my Alza.

😮 The Price Hike

Naturally, I went back to grab another bottle a week or two later. But to my dismay, the price had shot up to nearly RM135—almost matching the Shell Helix price. Yeah, I was a bit disappointed. But honestly? I get it.

If I were MotoLube, I’d raise the price too. They clearly know they’ve made something good.

---

🔚 Final Thoughts

If you can still find MotoLube 5W30 at a good price, don’t hesitate—grab it. It gives premium oil performance at a budget price (well, it did). It made my engine smoother, lighter, and more fuel-efficient, and that’s everything I want in a good engine oil.

Let’s just hope SK Hardware does another promo soon. 😅
