Two days ago i clean the injectors, i have a mystique 2.5 but its the same than a contour, after clean the injectors i try to start my car and didnt respond. It cranks but dont start the engine. The only that i did was clean the injectors, the battery its ok. Does anybody have any suggestions
 
and how did you clean the injectors? Took them out? Put cleaner in the gas tank? Cleaner in the vacume line?

Exactly what I wanted to know, and was going to ask, but then the internet crapped out. :D

Did you, by any chance, introduce cleaner into the cylinders?
 
I remove the injectors from the cylinders, obvious I disconnect some sensors but i conect it again everything and check everyone conector nothing happens

Welcome.

If you took out the ignition coil, make sure the ground strap is reinstalled.

Does the engine sound like it is turning very fast? If it is (you may have cylinder "washout", and lost compression), push the gas pedal all the way down (this closes the injectors) and crank. If that doesn't work, remove two spark plugs, put one teaspoon of oil in each cylinder, reinstall spark plugs and try cranking again. The oil helps the cylinder regain compression again.
 
apparently the injectors are not working. The fuel pump its ok, there is spark in the cylinder, i make test to the injectors and they are ok (the coil its 15 ohms). And i have check engine, The way that i clean the injectors was with carbon clean and air pressure (obvious that i activate the coil a lot of times)
 
Are your spark plug tubes wet at all after trying to start? Do they smell of gas at all? You may not be getting any fuel any. Is your fuel pump turning on? Did you check the fuses for fuel related issues?
 
Where is the fuses for fuel related issues
Once I had a similar problem my car did not start and the mechanic said to me that there is buttom of the safety. It is down in the driver side next to the pedals (there is a hole). This button this pressed (in my car), the cuestion is: does this button must be pressed?
 
The Fuel Safety switch inside the car (by your feet) must be pressed IN for the car to work. If the button pops OUT the car is not getting fuel.


When you turn the key to "on" the first time, do you hear the fuel pump prime? (a buzzing, whirring sound for about one second)? If you do, your fuel pump is working.
 
i check the fuel safety switch and it is pressed. The gas pump is working very well, but the injectors do not activate
 
Did you completely remove the FUEL RAIL when you took the injectors out? Or did you leave the fuel rail attached to the fuel line? If you removed it, check to see that it is fully seated at the quick connect . If it is not you should be seeing some fuel leakage at that spot.
 
the fuel rail it's fuel plenty and it don't have leak's. the injectors do not expel the fuel, some interlock that i have to check?
 
turn the key on and let the pump prime your fuel pressure, then check fuel pressure at the Schrader Valve (looks like a tire air valve) on the fuel rail. You can borrow a fuel pressure gauge from a parts store to check this.

Make sure you are getting fuel pressure (simply hearing the pump is not enough proof, really)
 
Here's my guess of what happend: the fuel reail and part of the fuel line got drained when the injectors were pulled. So maybe it took a considerable amount of cranking to get the line primed. Perhaps he didn't crank the engine long enough to get the fuel back into the rail.

Either way, the procedure stated above of how the injectors were cleaned (carbon remover and compressed air) is something I never heard of. I would be interested to see if it did anything.
