does anyone know how to install fuel injectors in here or any website giving information on guide of all the instructions

 

theyre somewhat precise. I suggest taking it to a shop unless you are very mechanical. There is alot more disassembly than it looks and alot of risks if you mess up.

 

is there a real damage pontential in installing the injectors becuase i heard its easy to do just takes time

 

It's very easy, but this has nothing to do with site feedback or suggestions. Moving to the newbie forum.

I know how to do it, but you'll probably leak fuel everywhere because I dont' know how to depressurize the fuel rail.

1. unclip the injectors (the wiring has plugs to each one)

2. unbolt the fuel rail (2 bolts)

3. pull the whole rail back an out (should take a tiny bit of muscle, but be gentle because you won't have a lot of room to work with the fuel lines still attached)

4. pull out the injectors from the rail.

5. put in the new injectors, put the rail back in place, bolt it back and plug the wiring harnesses back in.

Sharing what kind of car you have helps too, prettyboy. I can only assume it's that easy on the Evolution as wel.

If anyone can share how to depressurize the rail I'd appreciate the info for the future and I'm sure prettyboy could use it too.

 

If it takes more than an hour on a Lancer you should never touch a car again.

No real harm unless you somehow manage to damage an injector or spray fuel everywhere.

 

depressurize the fuel rail by removing the back seat and the little panel underneath. disconnect the wiring harness to the fuel pump(the only electrical looking thing there). start the engine and let it die naturally. you can try cranking it 1 or 2 more times to make sure there's no more fuel in the rail. there will still be some left so have a few rags. then unscrew your fuel cap. and voila! depressurized fuel system.

and a link for those of you concerned just cuz i dont own an evo.

Isn't that a little um...dangerous for your engine letting it run out of fuel? Or will it just die quickly rather than gradually lean?

Mine seemed to have very little pressure in the rail and I did not depressurize. From what I've read that means I'm taking out the fuel pump too because I may have a bad check valve.

 

no, its good. learned it in class, read it in books. it's safe. gas just stops being delivered. spark and no gas won't do you any harm. if you don't want to go through all that, just take off the fuel cap. there'll be more gas in the system, but will stop pouring out sooner than if you didn't.

 

where is the fuel rail located and does higher injectors in cc terms affect the cars performance in category of runing lean or richer

 

Thats exactly how i got taught to do it by the Ford Technician..

 

the fuel rail is the long pipe that the injectors sit in, which go into the plenum/intake manifold, just before the intake sid eof the head.
