  It might help the techs hanging around here to know what model '97 Pontiac you have.

  All my fuses are good just the injectors are not foreign none of them

  Which fuses did you check? #7 for the injectors and #8 for the PCM in the relay center? It's on the right side under the dash next to the glove box on the bottom of the A-pillar.
  
  You can feel an injector fire while cranking by touch. Or connect a small light bulb ?194? which just has wire leads across the connector that you take off the injector and crank to see if you see flashes.
  
  Are the spark plugs firing? Lay a plug on the engine with its wire connected while cranking and check for spark.

  I bought a 1992 grand prix se 3.4L that was built for racing and it is not wanting to start, it has fuel pressure and power to everything, I checked the power to the fuel injectors and it has continuous power with no break, which is not right, what is causing the this to do that and how can I fix it?

  This is an old topic but check the injector plug ins look inside them to make sure the contacts are in place
