Did you have the coil tested?

I have seen a bad ESC (electronic spark control) module cause a similar issue (weak spark and no power to the injectors).

BTW, I have moved your post into the appropriate section. Please try to post questions in the tech sections relevant to the vehicle and/or type of problem you are working with.
