cold start injector

[huntin5L]

I took off the throttle body and couldn't see the cold start for the life of me and couldn't find the information in the tsrm as to where it is located. UGGHHHHH

 

[IJ.]

Right up under the intake.

 

[huntin5L]

So it looks like i don't have to take off the throttle body. Ill have to try to reach for it underneathe with my hand.

 

[huntin5L]

God am i a fuck tard, i got it. That one screw is not gonna be fun nor is the hose that im gonna have to take off when i replace it. Will continue tomorrow

Relax, it's not that difficult. Less difficult than removing the TB. I hope you cleaned that while you had it out

 

[huntin5L]

I didn't lol, i should have. It always sucks working on my car, because I only have a few hours from the time i get off work to the time i go to bed. Im always on a time schedule.

 

[huntin5L]

well i couldn't get it out of where it was sitting, so i just pushed it down is much as i could and cleaned, who know what that will do. I tried taking the nut of at the bottom and gas started to spray everywhere, i think you have to hold down the bottom and loosen the one above it, but hardly any room to work.

well.. its part of the fuel system so its pressurized.. i changed mine one time... its kind of hard to get to.. definately need some skinny arms on this car sometimes... you can get it without taking anything else off though. soak up that gas.

As westonboege pointed out, the fuel system remains pressurizied to avoid vapor formation for a period of time after you shut the engine down. Called rest pressure, it needs to be bled off anytime you're going to open the system. You can do it the hard way (the way you did) or several other ways. One is to pull a vacuum on the FPR using a hand pump (engine off) for about 45 seconds. Another way is to pull the fuel pump resistor or relay connector while the engine is idling and let it starve.

 

[huntin5L]

Yeah i stuck a wrench right above the bottom nut and i pulled verrry hard to loosen it. I believe it was a 12mm i tried. Nada, wouldn't loosen and i didn't want to strip it.

 

[huntin5L]

now that i think about it. I should of relieved the pressure by taking that nut off the bottom, but does that detach from the injector when that nut totally comes out?

 

[huntin5L]

Anybody know?

 

[huntin5L]

i just don't see how the injector detaches from the fuel line.

 

[JustAnotherVictim]

isn't it held in by a bolt?

 

[huntin5L]

well the bottom bolt i unscrewed a bit, but it was spraying fuel everywhere so i tightened it back up. Im not sure if i completely remove it will it detach from the line.

 

[JustAnotherVictim]

I believe you have to remove that one. Take off the gas cap and remove the efi fuse to relieve the fuel pressure, let it sit for awhile and it should help to slow the fuel spray

 

[huntin5L]

hmmm...maybe ill give that a shot, but i think even with the line still on i couldn't push down the injector enough to see the tip of it. It hits the manifold and can't come down any further no matter how i jiggle it.

 

[JustAnotherVictim]

take the line off
you're gonna lose fuel no matter what

 

[Yellow 13]

Hope you dont smoke.

Yea, fuel will come out, but it will dry up and evaporate pretty quickly...You shouldn't mess with that CSI fuel line too much, I barely moved mine, and it broke off completely from the fuel rail... had to replace it, so be gentle with it!

Take off the banjo fitting to the CSI, then take off the two bolts (or maybe they are nuts?) and take out the CSI, while removing the connector at the same time. Should be fine.

Note: You will need a new gasket for it once it's off...
