Can someone tell me what is that mean?
ford focus ‘08
engine system fault.

 

If it stays on, suggest you have your vehicle checked for fault codes.

Of you can get near an Autozone, they will check for codes at no charge to you.

At this time we have no idea of what caused that warning to come on. Once you obtain some idea of why, with the code in the vehicle computer, then a decision can be made to follow up, if necessary. Until we have some idea of what it is trying to tell us , best to wait and see what the code(s) might be.There are times some warnings come up that are triggered by unrelated parts of the vehicle.

 

The truth is
i was cleaning the fuel injectors,
once i put them back this fault start to show up.
no crank no sound no nothing…
ive tried to replace the battery by new one but unfortunately is the same thing

 

Don't get upset, but this is why I ask so many questions before offering any suggestions. So you know this is coming,lol,
Why did you feel the need to remove the injectors ?
Did you remove any wires that came from the battery and went to a ground connection on the engine or firewall?

No crank, no sound , tells us the computer may not be recognizing the key now. Please recheck all your work, maybe you overlooked a ground connection in the process of assembly. Yes/No ?

 

Ok so I removed them because there was a fuel leaking from that area,
i just pulled the minus from the battery to do the work,
got about 4 injectors,clean them
don’t touch nothing that don’t need to be touched,
and then I reconnect the battery the problem started.

 

Right now we don't know if we have a fuel or ign problem..
One way to tell is remove one or two spark plugs and see if they are wet with gasoline or dry.
If wet, we have an ign problem, if dry, we have a fuel supply problem.
Let us know what you find and we can go from there. OK.

Did you install new injector "O" rings ?

 

hey there, sounds like a tricky situation. i'm not an expert, but maybe double-check all the connections you touched during the cleaning? sometimes a loose wire can cause weird issues like this.

 

For sure you absolutely right about that,
I double checked everything,
Although i did not touched no wire accept the injectors wire for the cleaning process.
it seems like i need a big boost to start the car and my booster (13apm)didn’t enough.
thank you all,I appreciate that.

 

no I didn’t replace the o ring they look good but maybe I should’ve

 

You said there was a fuel leaking from that area so you removed and cleaned them but you didn't replace the o-rings.
You remove and clean when you know they are clogged up. You replace the o-rings when they are leaking. When they are not clogged up you have multiport injection system, you can simply use the solution cleaner to do the work.
