Good day everyone here. For months now I've been having problems with my 2010 toyota corolla. The car hard starts. If I'm lucky it starts after the first crank in the morning but it takes too long, dragging before it starts. Other times the first crank would be unsuccessful and the second or third one does the trick and sometimes I need to step on the gas pedal for it to pick up.

Vehicle has been scanned and brought up some codes about misfire, timing and oxygen sensor.

Things I've done based on recommendations: serviced the injectors, changed spark plugs x2, changed fuel pump x3, timing change job done and yes the timing chain wasn't properly set, changed coils.

Yesterday was the worst, had to spend the whole day at the mechanic watching them work on the timing. I want to believe these guys are not sure what the problem is, I need help 🤲🏾

Thank you.

Thank you so much sir, it was the MAF sensor. Working fine now. I have learnt my lessons. Thank you much

RyanAutomotive:
Good evening sir,

Thank you for providing a clear description of your situation. Based on your explanation — a 2008 Honda Accord that starts briefly after an engine wash, then jerks and stalls, repeating the behavior on every start — this is not normal and is typically caused by electrical or sensor-related issues, especially following water exposure.

⸻

🔧 Professional Diagnostic Insight

1️⃣ Moisture Affecting Engine Sensors & Electrical Connections (Most Likely Cause)
An engine wash can introduce water into critical components, especially on older vehicles. Sensors and connectors commonly affected include:
• Mass Air Flow (MAF) Sensor – water can disrupt airflow reading, causing misfires or stalling.
• Throttle Position Sensor (TPS) – if wet, it may send erratic signals to the ECU.
• Crankshaft / Camshaft Position Sensors – moisture can cause incorrect timing signals, leading to engine shutdown.
• Ignition Coils & Spark Plug Connections – water intrusion can short the coil circuits, causing immediate stalling after start.

⸻

2️⃣ Check Engine Electrical Grounds and ECU Connections
Water may have seeped into wiring harnesses or connectors, especially around the engine bay or near the fuse box. Poor grounding can:
• Trigger ECU to cut fuel temporarily for protection
• Cause the engine to crank but not stay running

⸻

3️⃣ Fuel Delivery Issues (Less Likely, but Worth Verifying)
While mostly electrical after an engine wash, confirm:
• Fuel pump is operating consistently
• Fuel filter is not partially blocked (less likely sudden onset, but check if symptoms persist)

⸻

4️⃣ Engine Immobilizer or Security System Trigger
Some Hondas have a security feature that can cut fuel or ignition if the system detects abnormal electrical signals — this can happen if water touches immobilizer components or wiring.

⸻

⚙️ Ryan Automotive Workshop – Professional Take

A 2008 Accord should never stall repeatedly immediately after starting unless a critical sensor or connection is malfunctioning. Randomly attempting to start the engine without inspection may:
• Flood the engine
• Cause ECU misbehavior
• Damage ignition coils or catalytic converter

We always recommend a scan-first approach immediately after water exposure to identify active and pending fault codes before attempting further starts.

⸻

✅ Professional Summary & Next Steps

Immediate actions for proper diagnosis:
• ✔️ Perform OBD2 scan for active error codes
• ✔️ Inspect all engine bay connectors and sensors for moisture, corrosion, or loose contacts
• ✔️ Dry or replace affected sensors/connectors if necessary
• ✔️ Check ignition coils and spark plug connections for water intrusion
• ✔️ Verify fuel delivery consistency
• ✔️ Test immobilizer and ECU signals for abnormal behavior

Do not continue repeated starting attempts, as this can worsen the issue.

U are just wasting money alaye. Your engine na stubborn engine. See how mekanic just dey scam u like zombie. The issues lies with fuel pump wiring and fuse. Tell the rewire to check all the fuses and fuel pump wiring. If not u go kill the starter... u owe me 5k for this expo. Been thr with this same car 2 years back, either your fuel pump return hose is not connected r the o rubber inside the casing has blocked fuel flow.. stepping on the gas pedal would flood your cylinders and foul spark plugs with petrol and cause backfires and stalling. Your fuel pump wiring and fuse is the culprit. Its a rewire work and not meko. When una go ever geh sense.

Ur 2012 camry blinks R light wen n reverse is related to transaxle range sensor switch problem....clean the switch connector with spray or have it replaced

Check ur VVT timing sensor for lose of connector connection or being faulty, replace as appropriate

I use 2005 Toyota Corolla I noticed that it could not start because current is not transmitting from ignition to the key starter but the electrician could start it with a construction in the engine side, what is the issues ?

One won't know the issue unless they physically inspect and diagnose it.

Good day sir,

Thank you for the clear explanation.
Vehicle: Toyota Corolla 2005

What you described is a very common starting-system fault on older Toyota models, and it confirms that the engine and starter motor are okay.

Let’s explain it properly.

⸻

🔧 Professional Diagnostic Insight — Toyota Corolla 2005 (No Crank From Key)

Symptom Summary:

• Car does not start with ignition key
• No current reaching the starter from the key
• Electrician can start the car by bridging/jumping connections in the engine bay

This tells us one thing clearly:

➡️ The fault is between the ignition switch and the starter control circuit, not the engine itself.

⸻

⚠️ Most Likely Causes (From Experience)

1️⃣ Faulty Ignition Switch (Very Common)
• Internal ignition contacts worn out
• Key turns, but START signal is not sent
• Very common on older Corollas

This is the number one cause.

⸻

2️⃣ Bad Starter Relay
• Relay not closing when key is turned
• Starter works when jumped manually
• Relay may be weak, burnt, or intermittent

⸻

3️⃣ Neutral Safety Switch / Clutch Switch Issue

(Depending on transmission type)
• Automatic: Neutral / Park switch not sending signal
• Manual: Clutch pedal switch faulty or misaligned

The ECU blocks starter signal for safety.

⸻

4️⃣ Broken or Weak Ignition Wiring
• Cut, spliced, or burnt wires under the steering column
• Previous electrical work often causes this
• Voltage drops before reaching starter

⸻

5️⃣ Immobilizer / Key Reader Issue (Less Common)
• Immobilizer not recognizing key
• Starter signal blocked electronically
• Usually comes with a dashboard warning light

⸻

🚫 What It Is NOT
• Not battery failure
• Not starter motor failure
• Not engine problem

Jump-starting from the engine bay proves this.

⸻

⚙️ Ryan Automotive Workshop — Professional Take

Bypassing the system to start the car is not a fix.
It increases risk of:
• Electrical damage
• Fire hazard
• Sudden no-start situations

The correct repair is to restore the starter control circuit, not bypass it.

⸻

📌 What We Recommend (Next Steps)

Bring the vehicle in for:
✔️ Ignition switch test
✔️ Starter relay inspection
✔️ Neutral / clutch safety switch check
✔️ Wiring continuity and voltage-drop test

Once tested, we’ll tell you exactly which component is faulty and fix only that — no guesswork.

Hello everyone,

I have been having some issues with my Lexus rx330 AWD.

So if the car is parked for long like over night or for like 8hrs or more, it is difficult getting it to move.
Like in the morning if I engage drive the car won't move. I have to raise the engine speed for sometime before it will slowly begin move forward. Though once it moves it behaves normal if I disengage and re-engage the drive. The hesitation is no more.

This issues only happens with the drive gear, reverse works fine no matter when I use it.

I was suspecting a failing transmission pump but if this were the case the reverse gear will also be affected.

The transmission fluid level is okay and it doesn't smell burnt or look dark.

I recently did a filter cleaning like 6months ago.

I am seriously suspecting one of the solenoid valves that engages the forward gear or a blocked valve body.

Any suggestions?

My Corolla 06 usually delay when the gear is engage only in the morning or when the car is parked for atleast 5 hours. I scanned it and I got P0500, something related VSS fault /speed sensor. Pls who do I call? Rewire or mechanic!
I have also watched some YouTube video and I noticed the sensor is attached to the gearbox

You need to scan the transmission. The code will give a diagnosis for repair

That code has nothing to do with your issues. That code can just cause your speedo and odometer not to read again. The scan that was done only scanned engine related codes.

You need a high-end scanner to scan the transmission to pin point issues within it.

Your clutch bands and or pressure control solenoid is going out. You may also wish to check your trans filter.

Internal wear on the transmission components may cause this, but change the VSS and trans filter with fluid, If it still continues, and code still exists, plan to change transmission

Get a bigger scanner and scan the car for transmission code.
Get ready to replace the transmission, don't even think of repairing it tho

Hi all,
I drive a honda civic 2007 and i noticed my car temperature rises when i drive long distance and i had it checked the radiator was washed and cleaned as it should be done to clear any blockage in the passages, now it has reduced and does not over heat but when i get to my destination i check to see the water level in the radiator its almost dried up which means its still leaking somewhere and i do not see water droplets on the ground to confirm leakage and my mechanic checked if the top gasket is bad and he said its very ok. kindly advise on how to go about this please
