Replacing Fuel Injectors 85 Celica	Sign In

Im trying to replace my fuel injectors on a 85 Toyota Celica GT. Problem is there is hardly any room for me to get to them. I tired and got as far as removing the connectors to the injectors and after that I see how reinstalling the connectors would be next to impossible given the extremely tight space. I believe Ill need to remove the Air Intake manifold (im not even quite sure exactly thats what it is) to get to them. Im not quite sure though as the Haynes manual is a bit vague. And removing it looks quite intimidating as there are so many hoses and connectors. I dont wanna get anything mixed up. Most importantly, I dont want to create any work that isnt necessary.

I took a pic of my engine to give you guys a much better idea of what Im talking about....The injectors are on the left side of the engine...The fuel rail is directly under the Air intake housing/manifold. I removed the Air Duct and the accelerator and throttle cable have been removed but thats about as far as i was comfortable to go.

Any advice would be greatly appreciated.

Yes it is recommended to remove the air intake chamber. Here are shortened repair instructions. Good luck. You can label and number each hose and wire to be sure it is connected in the correct spot when you install it.

Disconnect battery ground cable and drain coolant system.
Disconnect air hose and pcv pipe.
Disconnect water hose and all necessary vacuum hoses.
Remove EGR pipe andegr valve.
Remove intake air connector,cold start injector hose and air intake chamber.
Disconnect injector electrical connectors, then disconnect fuel hose and pipe.
Remove fuel delivery pipe and fuel injectors.
Reverse procedure to install and note the following:

Check to insure that insulators are installed in intake manifold injector holes.
Install new O-ring onto injectors.
Apply thin coating of gasoline to injector O-rings.
Install injectors and delivery pipe as an assembly onto intake manifold. Check to insure that injectors can be rotated after they are installed in intake manifold.

Being way2old is why I need help from younger minds
