Need help having problems with my downstream injector. I have a 5.5 GPM Honda pressure washer, I was running a 2.1 downstream injector it worked fine then stopped working I bought 2 new ones , after troubleshooting it all kinds of ways it won't draw sh, bought a 2.3 it worked for a bit , now it's not sucking air , it throws the water out the injector, and it looks like the tip were it sucks it's burnt. all of my downstream injectors are doing the same, like it to much back pressure. What else can I do?
