Replacing Fuel Injectors
Hey Folks, It's been a while. My #2 fuel injector has died (>10 ohms) and killed my whole fuel delivery system. I've got 2 questions: first, can I replace it without removing the upper plenum, and if it's possible, is it worth it to try? Second, if one has died, should I expect the others to follow soon? It's an '89 w/ 92,000 miles. Thanks for the input.

you have to take off the plenum to get the injector rail out to get to the injectors.. while they are out you might as well send them to get tested and flowmatched by rich @ http://www.cruzinperformance.com/fuelinj.html
this is the only place to send with your injectors. ask around everyone will agree.
good luck

yeah you'll need to remove the plenum and runners to get to the fuel rail.well i would say if you can afford it replace all of them.what if another one craps out on you in a couple months?you'll have to do it all over again!
