I am about to buy 3 new injectors from internetautomart and will be putting them in soon. I must have it done in a weekend as this is my 500+ mile a week car. I have read the faq and plan on changing the rail connecting lines as well. Anyone who's done this have any tips so that my car will start right up and wont blow up? Any and all tips/opinions/angry responses appreciated!

also depressurize the system before disconnecting it. Have lots of rags, and dont forget to disconnect the battery.

 

use grease when you install the injectors to avoid nicking the o'rings

 

what kind of grease? I planned on using oil, but I'm open to better suggestions

 

just use a lil coating of vasoline and that should work just fine.

 

Clean the fuel rail seats with a q-tip and acetone to remove any build up that can cut an o-ring.

To remove the injectors use the jaws on a vice and lightly squeeze the injector, then hold the rail next to the injector and rotate the rail to free up the o-ring, then pull........pop pop she goes!

Thanks for all the tips guys! This is going to be my first "fix" on this car I'm doing myself, I hope all goes well. Also according to the sticky there are 3 gaskets I will need, but I was told only the plenum gasket will be needed. Which is it? Also do I need to use gasket sealent (Indian Head, etc) for this gasket? Thanks guys

 

Im a dumb newbie. But what made u buy new injectors. Just replaceing the orginals or did urs just crap the bed. I have a ruff idle, and the performance of my car tends to be inconsistant, should i look into new injectors? I got 143k on a 92

 

The reason I am replacing injectors is because there are three that seem to be leaking fuels. I already had the o-rings replaced and that did not help. The fuel looks to be leaking directly from the injectors
