[CavemaN1010]

HI

Not often on here but im a man in desperte need my 2005 import has been up to now very reliable but i go to start it after work and it just keeps turning over but not fireing, had the RAC man out and he could not connect to the cars computor, so i have a couple of questions

 

1... never noticed before but when you turn on the ignition does the cooloing fans kick in straight away as they are at the mo

2... can you normally hear the fuel pump pressurise as you turn on the ignition as the RAC man seemed to think you could

3... he sprayed easy start up the air filter and it still didnt try to start so could that mean its not fuel related

 

I know its probably impossible to diagnose like this but im after ideas or if i get really lucky someone may have come accross this problem before either way any help will greatly recieved

 

thanks

Mike

Answer to question 2 is Yes

Answer to question 1 however i don't think i have ever noticed then spinning up straight away

 

Have you checked battery is still in good order, recently in the cold weather people have been suffering bad batteries, me included

1 - no they should be temp related i.e linked to a sensor

 

2 - you should hear the pump prime as the ignition turns on

 

3 - no necessarily not fuel related, maybe not enough getting through to ignite and no fuel

 

possibles - fuel pump, fuel pump fuse, fuel pump relay, cam/crank position sensor, immobiliser fault that is cutting the fuel/ignition

 

food for thought, you need to read the codes really, sorry it's not much help

I thought I had an issue with my engine fan a month or so ago - it seemed to be running all the time, even on start up. After posting a question on here about it I was advised that it may have been where my AC was on as this will start the engine fan up regardless of actual engine temperature. I turned off the AC and this resolved the engine fan issue.

thanks for the help .. i did make sure the a/c was off and pulled the fuse for the fan next to the battery and one went off but one stayed on ...... couldnt hear the fuel pump prime so the "possibles - fuel pump, fuel pump fuse, fuel pump relay, cam/crank position sensor, immobiliser fault that is cutting the fuel/ignition" seem worth a look at and i wish i could have got the codes but the RAC mans diagostic comp would not connect with the car .......... does an import still connect to uk diagnostic units or is a different unit needed, i dont know too much about the to be honest

If you want I'm happy for you to borrow mine to read your codes, but might be more convenient for you to get one as I'm based on London.

Is the noise on start up not the throttle body rather than the pump?
