This may make me sound like an extreme smart-***, but are the injectors getting an adequate amount of fuel?

 

no it dosnt make u sound like a smart *** hahah i asked my self the same thing today a few times haha ... yes they are gettingn enough fuel but they wont spray...

 

They sound clogged badly.

In the past, I've just run some fuel injector cleaner through my fuel system to prevent that, but I'm not sure how to clean them once they are clogged... Try to confirm this first though.

 

thanks i will look in this tomm....... anyone have any other ideas i can check

 

you're sure your fuel pump is working right? the fuse ok?

have you changed your fuel filter yet?

or yeah, might be just the injectors clogged.

 

yes I'm sure the pump is working and i don't think that the filter is clogged...... but i took off the fuel line after the fuel filter and turned the car on for a second and fuel was pumping out..... so that can only mean its working

 

are they the stock injectors or did you do a swap?

 

nope they are the stock injectors...... the car was running fine and all of the sudden stopped working one day..... it will run wiht eather sprayed in it..... but will die when i burns off all the eather

 

anything????

Use a 'node' tester to make sure they are getting signal. DO NOT USE A TEST LIGHT. No signal, trace your electrical to find your answer. Oh yes, hours of fun with wiring. Good luck.

 

i will be checking it wiht a node light as soon as i get one..... and i was told today that even if i ahve some fuel pressure if i dont have enough it still wont ifre is this true i have to pressure test it also now..

 

i know somone here knows that easy question

 

Yes, you need the correct amount of fuel pressure. Your car is computer controlled, so the injector only opens for a specified time. As a result, if you have low fuel pressure you won't get enough gas into the combustion chamber and that magical stoichiometric equation just won't happen. Good luck.
