my fuel injectors seem to not be working, dcauto will sell replacement ones for 30$ but they are use does any one know of a cheaper place, or have some ones they are willing to part with.

have you tried cleaning yours? They can be cleaned. YOu can buy a kit off the internet that contains the upper screen, o-rings and tip cap. Napa carries a kit that contains just the tip cap and o rings but not the screen. I used carb cleaner to clean mine out, tapping them up side down on a block of wood to clear the gunk out of the upper screen.

it seems unlikely for all injectors to go bad at once and need total replacement.

[masterdave]

yeah i cleaned them and replaced the O rings when the problem started happening. I dont think they are all bad. if i remember correctly #1 is defiantly bad and i think 2 or 3 is intermittent. But the car wont even start up any more, for a while i could get it started but now it wont even catch.

Send them here: http://www.southbayfuelinjectors.com/servtree--.html

For $15 apiece they'll clean, thoroughly test, replace all screens and seals, flow match, etc, etc. They'll basically be like new.

I've used them before with good results.

have you checked your fuel pressure and your fuel pump volume capacity with specs?

[masterdave]

yeah the pressure was fine, at first i though that was the issue so i replaced the check valve and all the fuel lines around the pump, ill retest when i get home on sunday but as far as i remember it was not the issue.
