Chevrolet Repair: 0023 chevy s10, residual pressure, fuel rail

Question
I have a 2003 s10 2.2. I ran out of gas and when I put gas in it it still fails to start. It fires and has fuel up to the fuel rail. I am stumped.

Answer
HI JEREMY,,YOU SAY IT FIRES,MEANING THERE IS SPARK ??? [IGNITION] OK SO IF THERE IS SPARK DO YOU KNOW WHAT KIND OF FUEL PRESSURE YOU HAVE. JUST BECAUSE THERE IS FUEL UP TO THE FUEL RAIL DOES NOT MEAN THERE IS ENOUGH PRESSURE. COULD BE JUST RESIDUAL PRESSURE...IF YOU DO NOT HAVE A FUEL PRESS GAUGE,HAVE SOMEONE CRANK THE ENG OVER FOR 5 TO 10 SECONDS WHILE YOU HOLD DOWN ON THE CK VALVE ON THE FUEL RAIL,,[IMPORTANT] NEXT STEP. THE ENTIRE TIME THAT THIS ENG IS CRANKING THERE NEEDS TO  BE FUEL COMING OUT OF THE SHRADE VALVE. IF SO THEN MORE THEN LIKELY THE FUEL PUMP IS OK..HOWEVER IF THERE IS FUEL THERE FOR THE FIRST 1 OR 2 SECONDS THE FUEL PUMP HAS FAILED..IF THE FUEL PUMP IS OK AND THERE IS SPARK, CK THE TIMING CHAIN FOR PROBLEMS. LOOSE OR JUMPED TIME.. GOOD LUCK, HOPE THIS HELPS YOU,,,TOM
