1993 Toyota Camry No Spark

[DAZR]

Hi everyone.

Darryl from Shepparton here.

This is my first time posting here.

I have a friends 1993 Toyota Camry SDV10, 2.2L 5S-FE. It has been sitting for approx 4 years.

I am trying to get it running so she can sell it, as she is under a bit of finacial strain.

It turns over, but no spark. Will not fire even on Start Ya *****.

I have replaced the Distributor Cap, Rotor, Spark Plugs and Ignition Coil. Did not fix the issue.

I have checked all fuses, they are ok.

Is there any relays that I need to look at, and the last thing I was going to replace, is the Ignitor on the mudguard. Do these go bad?

I am scratching my head as what else it could be.

Thanks heaps for any suggestions.

Hi Darryl, I am going to take a guess that you ay have a bad crank angle sensor mate. The ignitors rarely go bad on those engines and the engine itself is known to be pretty bullet proof. If the car has been sat for too long, the it's usually the small things that tend to go bad.

You mentioned that it wouldn't even start with that spray, which would indicate no spark despite it getting fuel vapor to get it started.

If you want to learn how to test one, search it up on YouTube University and there are plenty of videos to choose from. if it tests bad, then replace it, and I reckon it will fire right up provided the injectors aren't stuck.

Let us know how you go mate.

Here's a snippet as to why the crank angle sensor is important in a no start situation..

The Toyota Camry SDV10 with the 2.2L 5S-FE engine has a crank angle sensor, also known as a crankshaft position sensor. This sensor is crucial for the engine management system to determine the crankshaft's position and speed, which is then used to control fuel injection and ignition timing. 

 

The crank angle sensor is typically located near the harmonic balancer and the crankshaft, often on the passenger side of the engine block. It sends signals to the Engine Control Module (ECM) to synchronize engine functions. 

 

Here's why it's important:

• Fuel Injection:

  The sensor's signal helps the ECM determine the precise moment to inject fuel into the cylinders. 

   
• Ignition Timing:

  The sensor also provides information for the ECM to time the spark plug ignition, ensuring proper combustion. 

   
• Engine Speed:

  The sensor monitors the crankshaft's rotational speed, which is vital for many engine control functions. 

   

A faulty crank angle sensor can lead to various issues, including:

• Check Engine Light:

  A common symptom of a faulty sensor is the activation of the check engine light. 

   
• Engine Starting Problems:

  The engine may refuse to start or stall due to incorrect fuel injection or ignition timing. 

   
• Rough or Misfiring Engine:

  The engine may run roughly or misfire if the sensor is not providing accurate information.
