:frown:HELP IVE BEEN WORKING ON MY KIDS BLAZER FOR EVER AND STILL CAN'T FIGURE IT OUT. WE REPLACED THE FUEL PUMP, FUEL PUMP RELAY , FUEL PRESSURE REGULATOR , OIL PRESSURE SWITCH , INJECTORS , FUSES , GROUNDS , FILTERS , HE HAD TWO BAD KINKS IN THE FUEL LINE WE FIXED . STILL IT WILL START AND THE INJECTORS START OUT WITH GOOD SPRAY OF FUEL AND WITHIN FOUR OR FIVE SECONDS THEY LOOK LIKE THEY RUN OUT OF FUEL AND IT DIES , IT STARTS EVERY TIME BUT I HAVE TO REALLY MESS WITH THE THROTTLE TO GET IT STARTED AGAIN , AND IT RUNS FOR A FEW SECONDS AND DIES AGAIN . IF ANYBODY HAS ANY IDEAS PLEASE HELP US OUT . THANKS SO MUCH :)

Just a thought...did you check to see if there was any crud in the fuel tank....it could be getting sucked onto the screen when running and when it is off it could be "floating" off the screen...or maybe the screen is collapsing on itself...it is 23 years old.
