Hello all,
First time posting and I am very hopeful that someone here might be able to help as my car is driving me mad now. About 2 months ago my car started having difficulty starting. it is an 07 accord cTDI. This could happen at any time, cold or warm, but it seemed to be worse when warm. It might start first time or it may take 20+ goes. When the key is turned to the 2nd position (before starting), if the glow plug light comes on then the car will start. It will then run as normal. If that light does not come on then you will get a message on the dash saying "VSA check system". The car will crank over but will not fire.
Things we have changed to try and sort this out:
1. New battery (this was first thought)
2. New fuel filter
3. New key transponder in the car.
4. New fuel rail pressure relief valve
5. New fuel pump solenoid.
All this as well as taking all the electrical connectors we can find apart and cleaning them. We have even checked the fuel filter inside the tank.
The problem remains.
The car has been to a couple of garages and they do not agree as to what the problem is. Honda have tried to sell me a new ECU (£1200) and another garage say that is not the problem but that all of the injectors have gone bad (£800).
After more research on the internet we are starting to think that it is a problem with the main relay on the car. There seems to be a lot of people who have had problems with the soldering going bad on the circuit boards. The issue is that we cannot find it. All the diagrams are related to cars from the USA and it does not seem to be an exact mirror of the UK cars. Does anyone have an idea of where this main relay is? Does anyone have any other ideas as to what may be causing these issues?
Thank you in advance for your ideas
