i got an lt1 intake complete with injectors and fuel rails, it was all assembled when i got it. the intake has oxidized, it looks like it maybe sat outside for a while and i'm worried that the injectors might be gummed up or something from sitting around. is there a way i can check that fuel will flow through them or that they're otherwise ok?

 

Theres this device(forgot what its called) anyhow, they connect a negative and positive terminal to each of the injectors, and you can hear the pulse being thrown from the injectors, We put some injector cleaner and it worked, Shouldnt cost more than $10.00 at a shop that carries this device. We have one in our shop.

 

Ohm metre should tell you if they are any good... should be between 16.0 to 16.9 if they are anygood

 

Resistance check will only tell you if the coil is good (which is a good idea to start with) but won't tell you how/if they flow.

For about 50 bucks you can by an injector tester (forget the real name of it) that cycles them on/off...not sure, but I don't see why you couldn't run a non-flammable solvent through them while testing and monitor the pressure drop...this would tell you if they all are close in flow.

Next, you'd want to look at the spray pattern, make sure none are "dribbling", etc., nor none are leaking.

So, you'd need a fuel pressure gauge, external pump capable of 45 (or so) PSI and the tester/cycler., then hotwire to a 12volt source to run it all.

You may just get ahold of Rich at www.crusinperformance.com, he can clean and flowmatch them all for about a $100.00, he may even do you right just to check'em out for you.
