there bleeding down takes 3 trys to start ..do i need to repace them or can i just clean them.must be because it sat for a wial befor i bought the motor....

 

Fuel pressure loss can be caused by several things besides leaking injectors. A faulty FPR, a faulty fuel pump check valve or a leak in the lines. How do you know it's the injectors?

 

have to crank the car 3 times to crank.tryed the ol prime the pump 6to8 times then try to crank then its flooded checked presser bleeds down within 15 sec .so i would think i have a bleeding injector .would that not be the reason its hard to start.cause gas pooring in when off..car i got the motor from sat in the juck yard for over a year...

 

As I stated above, there are multiple things that would cause your fuel system to not hold pressure. Here's a write-up from Shoebox that might help: http://shbox.com/1/4th_gen_tech2.htm...essure_testing

 

If you think its leaking injectors, pull the rails, injectors intact, and pressurize the system. You'll know real fast if the injectors are leaking.
