Immobiliser, Ecu, Key Coding, Car Cranks But Does Not Fire

[hassan]

Ford Galaxy 2.3 LX 2002 Model Petrol on an 02 Plate, 90,000 Miles

This is a really strange and somehow unusual story. 3 weeks ago I parked this car after returning from office. It was Wednesday evening. On the following week on Monday I started it and surprise, it refused to start. Engine spins, starter motor spins the engine but it does not fires up.

 

Called RAC as usual, he said it fuel pump

Checked the Forum, which suggested that it might be infamous Relay 30

Called a diagnostic guy, he checked it and found no error (Yes absolutely No Error Code) so he said it could be Immobiliser problem.

The lights on DOOR was first few seconds solid red, and when tried to start, it was blinking so He tried to re-programme key but failed , message read

Hi Hassan,

 

Not sure if this will help but I had the same issue with my 2002 TDi Sharan, I was convinced it was the immobiliser BUT it turned out to be the CAM sensor, I just happened to disconnect it and the car started although it took a few more turns than usual to start.

 

I have now replaced the CAM sensor and it starts nay bother, I know you mentioned that there were no error codes it's something you could try easy just by unplugging the sensor and try to start it.

 

On my Sharan there are two sensor connectors at the front of the engine block just behind a ball shape thingy, you will find two one is black and the other a gray connector, the CAM sensor is the one that leads to towards the timing chain cover towards the top.

 

Give it a shot just in case.

 

Regards

Hi Tona955:

Honestly speaking I am tired of this car. I have been dring and owning cars for the pat 30 years bu Have never seen an automobile which is so complecate, difficlt and un-willing to strart.

 

Today I changed its Relay 30 which seem to be a common problem with these cars. It was hell of a battle to open the fron panel and replace the relay but somehow I managed to do it. Then started and buzzzzzzzz did not start again and now I am tired of spending money on this and getting rid of it, It was better to buy a Honda or Mitsubishi MPV which faaaaaarrrr more trustworthy and easy to repair

 

All of you have fun with these galaxies
