John,
swap out the injectors (with each other) and try again before you blame the injectors.

This afternoon I had one off my flying friends over and we pulled the plane out of the garage and tried a first start.  I thought the Weber would be a no brainer, so after checking for spark, I turned on the fuel and the low pressure pumps.  No fuel at the Weber and the low pressure gauge is not functioning, I found later as I tried the pumps and the fuel flowed into the Weber, as the needle valve didn't hold this time.  Tomorrow I'll check the fuel pressure with a manual gauge and order up the higher pressure needle valve that Lynn mentioned, if he gives me a heads up as where to find one.  Next I turned on the high pressure pump, flipped up the cold start switch and the engine started, it will run with the cold start switch on, but on checking we found that only one injector is working.  The injectors where ones I got from Bruce T. which were rebuilt, so maybe I need to get a new set, as it is a real project to get to the primary's under the over the top intake manifold.  Lots of things to check out tomorrow.  One thing, it didn't make that nasty noise running on one injector and exhausting through the Hushpower II muffler, but it did sound real good running for the first time.  JohnD
