Hi,

I am sorry that you have not been helped yet. I just came online and saw your question.

Ok, by temperature control valve, do you mean the control valve on the heater hose or do you mean the engine coolant temperature sensor. Bit confused on which you are referrring to.

sorry its the heater control valve that has four hoses connected to it.
Customer reply replied 2 years ago
I changed the valve due to the heater not working. I was told that the valve was probably stuck shut so I have replaced it with a brand new valve. I topped up the coolant and went to start the car so coolant would circulate through the new valve but the car would not start. No problems starting it previously. Not sure if this has any bearing but the car is normally parked on a flat road. When doing the work I parked the car on our drive which is on a slight incline.

Hi,

That repair should not affect it as far as starting. have you tried some starting fluid to see if it will crank and run for a couple of seconds with it

No not tried that yet. I've just fitted new plugs, more to eliminate the plugs more than anything else. Still no joy. The old plugs look dry
UK Auto Mechanic: Eric, Automotive Repair Shop Manager replied 2 years ago

Hi,

Ok, try to start with the starting fluid. If it does start for a few seconds, then we have a fuel issue - either no signal from the computer to the injectors, fuel gage incorrect and too low on fuel, or fuel pump not delivering enough fuel pressure to start

Managed to get some easy start. I've sprayed it up the inlet and tried to start the engine 4 times. No joy. I've had jump leads connected from my car too so that there is plenty of battery power. It turns over well, its really trying but just won't fire up.

HI,

Is the security light on the dash staying on constantly or blinking?

Ask Your Own UK Car Question
Customer reply replied 2 years ago
It is blinking with no key. When the ignition is on it stays on for two seconds then goes out completely
UK Auto Mechanic: Eric, Automotive Repair Shop Manager replied 2 years ago

HI,

Ok, try disconnecting the battery cables for 10 minutes and then reconnect and try to crank it

Customer reply replied 2 years ago
Left the battery disconnected for 15 minutes, reconnected it, still cranking but not starting
UK Auto Mechanic: Eric, Automotive Repair Shop Manager replied 2 years ago

HI

Ok, I am going to opt out at this point as I am stumped. I will open it back up to other experts to see if any know what the issue is

Ok thanks for trying. I could do with getting this sorting asap as I can't even get the car to a garage.

I have a Ford Focus 1.8tdci 2009. I'm having trouble starting the car. I put the key in the ignition and the red immobiliser flashes rapidly and the car won't start, won't even try to start. I have used the spare key but doesn't make any difference. It ran briefly last night for 10 minutes parked on my driveway. The engine management light came on with a message 'acceleration reduced'. When I turned the car off, it refused to start again with either key. I haven't been able to drive the car for the last few days because of this. Any ideas what the problem might be? … read more
