So I have a 1999 S10 4X4 ZR2, rough idle (barely idles) and begins to idle correctly after a few minutes, once the engine starts to idle correctly and the accellerator pedal is depressed the engine will act like it dies and will not idle up. After checking fuel pump which seems to act like it is unable to create pressure and sounds rough, there's not a high pitch that is typical of normal operation. I am questioning whether I need to replace fuel filter or the pump? Also when the accelerator is pushed the engine begins to misfire. Any helpful thoughts/advice is appreciated.
