I am going to be replacing my cold start injector soon as that is what I think my problem is. Does any one have any instructions on how to do it? it doesnt look like I have to take off the plenum but the chiltons book says I have to. I dont see how taking off the plenum would help unless I am looking at the wrong part.

Can someone please give me some advice on how to change this part.

 

cij is on your drivers side in between the second and third runner from what i can remember disconnect battery first then there should be a torx bolt holding the cold start injector down. pulling off the plenum will make life easier as removal of the threaded feadline on the rear of fuel rail will be necessary so you wont tear the oring that slips on the end of it but if you want to take the chance just remove that torx bolt pull off the old cij and slip on the new one
