I can't tell you how to spend your money, as far as parts and testers. It's your money, your decision. All I can do is give you ideas.

I don't know how you checked for voltage at the injectors? If I was looking for voltage and didn't care about the ground side, I would use a 12 volt test-lite. So you see, here we go again, if you don't have a test-lite? I can't tell you to buy all this stuff.

If you use a test-lite, ground the alligator clip to a metal part of the engine, that you think is a good ground. With the plug loose from the injector, touch the pointed end of the test lite to one terminal or the other, with the key on, you don't have to crank it. The lite should come on.

If the computer doesn't see an rpm signal, it won't ground the injectors.

I can't believe you replaced all those parts and didn't know how to check for spark at the plugs. Even if your just killing time, shooting the breeze. Ha, I'm doing the same thing. Every post I make, gives me more credibility on this site. I don't mind talking to you. thanks
