I HAVE A 1997 BUICK REGAL 3.8 SUPERCHARGE, THAT IS NOT RUNNING, I WORK FOR FIRESTONE AS A G/S, EVEN THE LEAD TECHS AT MY JOB CANNOT FIGURE OUT WHAT IS WRONG WITH MY CAR, I HAVE PUT A FUEL FILTER/FUEL PUMP/NEW FUEL INJECTORS, THEY HAVE RAN THE CODES ON IT, USED THE SMOKE MACHINE ON IT, HERE IS WHAT IT IS DOING. ABOUT A MONTH AGO IT WOULD JUST DIE GOING DOWN THE HIGHWAY AT HIGHWAY SPEEDS AND NOT RESTART FOR ABOUT 15 MINUTES, AND ALSO WOULD TRY DYING AT STOPS AND TO POWER BRAKE TO KEEP CAR RUNNING. NOW IT WILL NOT RUN PERIOD. IT WILL START BUT CONSTANTLY FALLAS ON ITS FACE. WHEN IT STARTS GAS PEDAL IS FLOORED AND IT VARELY REACHES 2500 RPM AND THAN DROPS TO NOTHING SPIT AND SPUTTER AND BUILDS UP RPM'S AGAIN, ALSO HAVE CHECKED ALL COIL PACKS TODAY, EVERYONE SPARKS, CAN YOU GIVE ME SOME IDEALS ON THIS PROBLEM

Hook up a fuel pressure gauge and a spark tester that you can hook to the spark plug wire and tape to your window (you can get them at most auto parts stores). Then try to start and run your car.
This test will tell you whether the problem is in the fuel system or the ignition system. After you know that you can narrow down the things that might be causing it. Let me know what the test shows.
