Is This a electrical problem in my blazer or what?

Sounds like the coolant temp sensor maybe acting up. Check that its plugged in right and that the wires are not cut pinched or grounding out.Or possible that the oring on the injector got cut when you installed it.Take some wd 40 and with the engine running spray it around the injectors. Notice the engine either speed up or die if so that's the injector seal leaking.Without seeing the car that about all I can suggest right now.Good luck hope I helped.
