I HAVE A 1989 FIREBIRD V8 TBI FUEL SYSTEM THAT WILL NOT GET ANY PRESSURE TO THE CARB. i PUT A NEW FUEL PUMP ON AND CAR RAN FOR ABOUT 20 MINUTES. NOW IT SEEMS LIKE SAME PROBLEM. I HEAR PUMP RUNNING AND IT PUMPS FUEL BUT NOT WITH ANY PRESSURE. CAR WILL NOT START. PRESSURE BUILDS IN TANK WHEN YOU TAKE CAP OFF. ANY THOUGHTS? BOB
