i think my fuel pump is bad. Hooked press guage to schroeder valve and got 32-35 lbs at idle pressure. also when turned key to "on" but not cranking car, it jumps p to 35 for a few seconds, then falls down to 20lbs. is that the pressure baffle in the pump letting go? I am thinking my pump is going bad and getting worse. I have a 93 w/ LT1 V8 and 24 lb/hr Bosch injectors. I have had a new f.p.regulator I got a while back, but haven't installed it yet. I think the pump is bad, not the fpr. Is this sounding like a correct diagnosis? Help please..thanks!!
