99 blazer won't run

arabian49 · 11-03-2009, 11:41 AM

Have a 99 blazer with 4.3L Automatic. Starts right up then dies. If I dribble gasdown the throttle body it continues to run. The injectors are not firing. No security light blinking. Good fuel pressure (61Lbs). Just for grins I disconnected the passlock sensor and used a screwdriver to turn ignition switch. Same story, starts then dies no security light flashing. Anyone have any ideas. Scanned it with a odbII scanner and there are no DTCs stored. Since this scanner is more for emmission don't know if it would show codes from the BCM. Appreciate any ideas.

My 1998 blazer did the same thing I don't know how much pressure the line had but it would start and die, I poured gas into the motor and it would run, It turned out to be a fuel pump for me which sucked cause it was about $300. Could try hitting the gas tank with a bar or hammer then try, it might start up and run, if so it's the fuel pump and I wouldn't go to far with it untill it's fixed.
