    The other day, upon arriving home, my 1989 K5 Silverado Blazer started to "sputter". I wasn't getting full power from my throttle when I accelerated, but it was very sparatic and the problem seemed to go away. However, the next day my vehicle won't start. If I spray starter fluid directly into the carb, it will start briefly, but stall as soon as it burns through the small amount of started fluid. This leads me to believe that I have fuel delivery problem. I have purchased a new filter, and have not installed it yet due to reluctance to mess with the slightly corroded fuel line. I know it may be the pump, but it's in the tank and I don't want to drain/remove it if I don't have to. Any suggestions? Thanks in advance for your help.

    check for spark

    check for ses codes

    check for 2 sec. fuel pump hum when key is first turned on

    check for fuel coming out of injectors when cranking

    if all checks out hold foot to floor and try to start truck, if it starts look at idle air control valve

    also could be coolant temp sensor. (look for ses code for this one)

    My 88 had a similar problem a couple years ago.
    Turned out to be the fuel filter on the frame rail was plugged.
    Simple to change. Also, as mentioned, check for codes. I think mine had something like a code 43 set. Does sound like fuel problem

    I had a similar peoblem with my '90 burb. After replacing the fuel pump and filter, I was advised on this board to change the ignition module. I replaced it and it's been running great ever since.

    First thing you should do is check for trouble codes. http://www.troublecodes.net/GM/
    Then Beings you have it .Change your fuel filter. It is an easy job. Should change at least every 10 K to keep your pump healthy.
    If the problem is still there and there are no trouble codes
    I would suspect the ignition module.
