I just went out in my blazer and started it. As soon as I put it in gear it died. Now all of the sudden it is doing this every time it is in gear and idling. In park it seems to do fine, it just dies every time I put it in gear. I took off the air cleaner and it looks like the injectors are putting out good fuel. Anyone got any ideas as to what it might be? I hear the fuel pump in the tank come on every time prior to starting. It is an 87' with a 350 tbi.
