Injector tester.

So I was thinking, I have a spare lower intake, and get a spare fuel rail and injector harness. With that said, Could I pull my injectors, run the harness off of a separate voltage controller and find any real problems with my injectors? I would assume so. I don't really care if I could send them elsewhere to have the same thing done, I am looking at no down time here. What does anyone think about this?

Re: Injector tester.

If you pressurized the fuel rail with a liquid. Actually running injector cleaner would serve a purpose here.

Of course you need to energize the injectors also to get them to open.

But why not just pressurize 1 injector at a time, via a simplier way. The intake isn't helping you except to hold the injector.

Re: Injector tester.

Well I guess my point was that I would use the manifold to run all 6 into beakers (Ild make some kind of jig, if thats what you would call it), and let em fill to a point and I guess if one filled more or less than others there would be a problem. I thought about making something to use low voltage to match what the ECM does. Plus, an extra manifold sitting around is somewhat useless, might as well put it to use. Plus I thought with an extra rail it would be a lot easier to set this up. One at a time could work fine too but I also have an extra AFPR sitting around that I thought was bad but turned out to be good. Also happen to have a Walbro laying around as well. It could be a personal fuel system testing station :lol: Doing this would show problems with an injector if it had a problem right? I.e., if there were one sticking, I would more than likely see it right? One reason I want to do this is because I think I do have a bad injector. Over the last week or two, the WB will be hanging out between 14.3-14.8 at idle (normal for me), but now it will drop to the 9's and 10's for a split second about every 1-1.5 seconds, as if one were leaking or staying open? Also FP has dropped a pound. Going to test pump today by blocking line off and watching pressure. It drops about 1/2 pound every five seconds when the key is on engine off. But still, making this injector tester would still be useful in the future I imagine. Would just be nice to have around to rule things out I guess.
