How do you replace the fuel injectors on 2003 Toyota Echo?

Answer 1

requires the removal of the top engine cover, the spark plug coil "all 4" may need the removal of the air filter housing to have better view and access ALL WAYS COVER THE THROTTLE PENNING use a rag if not have a plastic cap on hand ; **the wire harnes can be muve a side after disconectin the battery first and all the conectors around the injectors AVOID STRETCHING BAY FORCE**

It will need to remove the valve cover (it's better to replace the gasket) if no oil licks are present Previously; It is possible to reused de same seal while this does not present any fracture, any hardness particularly at the exhaust/fire wall side are where the seal's settles in the V.C.G. You will need some rags and brake cleaner to wipe out any oil in the gasket and in the cover IT IS preferable to have the seal & the surface of the head where the seal's settle to be clean and dry.. to reinstall you can use Silicone by applying just a thin coat in both side of the seal and a small amount in the junction areas----- for reinstallation just reverse the process----- Ones valve cover out cover the opening with a clean towel and procced in removing a bolt at the rear right of the engine(where the engine connect to the transmission) fallow the fuel line where connect to a metal pipe begins to bent and usually the connection is cover with plastic bracket you can slide it out (spraying WD-40 first) in Down worth direction ones out just push the sides (usually Square in Gray color)and pull to disconnect place a rag for the fuel that will spill (remove the gas cap & reinstall before restarting engine) using a 12mm socket remove the 2bolts that hold dawn the fuel rail *do not miss the two spacers sitting between rail & head* before removing move the injector side by side to loosen up the injectors then carfuly star pulling the rail ones out cover the hole's to be safe noting fell IN now replace the injector if possible all the seals in the rest if only raplace one injector; to reinstall use caution do not force the injector in the rail (use WD-40 just little be) and to place them in the head place first the spacers fallow by the injection rail all injectors must fit in smooth and with the connector pointing up-worth all in the same high NOW A BAD TIP try not to STAR the engine just turn the ignition on Position II;; secure the injectors (the 2bolts 12mm) ;; connect the fuel line at the other end (connect it and pull it just little to be sure is secure place a rag just in case);; done this connect the battery terminal for 10sec. and disconnect do this three times if no fuel leak-out you are good to go REINSTALL everything in revers-order BUT IF IS any leak appears during the connection of the battery IMMEDIATE disconnect the battery(no need to remove the key) clean the spill of gas and fix the lick reinstall and try the test again if all good NO leak is seen any more you are done with this problem and with-out removing everything to repair the leak of fuel WELL AS I SET reinstall all the components in the back order in witch they were remove and at the very end connect the battery and tight it this time ( if acid is present cleaned with bakingSoda and water use extra water to rains-off all of it) I will post some pic. latter and some diagrams of the repair because just by coincidence I'm going to do a similar job tomorrow.. hope this my help you thank you... ...
