I am sure you have double checked your readings and verified your meter is functioning properly. Also not hearing them fire is a good indication. Hate to hear you having this issue. I will also be looking into the injector power modification in the very near future. I recommend that you use a dremel tool to allow access to your injector cap head bolts when you remove it. I saw the write up on this forum. This allows you to remove the injectors without removing your plenum. Good luck resolving your issue.
