1997 Suburban dies after initial start-up?

Question

Upon an initial start(most of the time), the engine spits & sputters like its starvin' for fuel and usually stalls, after the re-start it drives around just fine. Fuel filter? Fuel pump getting weak? Just guessing...

Thanks,

Shawn

Might be the fuel pressure regulator going south.Brian

The most common problem for this symptom is that the fuel pump which has a check valve in it is letting the gas drain back into the tank after you shut it off.  To prove this you can hook up a fuel pressure gauge to the test port under the hood and see if the pressure slowly goes away.  Another way to check this condition is when you jump in to start it up cycle the key a couple of times before you let it crank over.  When you turn the key from "off"  to "run" the fuel pump is energized for about 2 seconds.  You can actually hear it if you are listening for it.  By repeating this a couple of times you are filling up the fuel line again.  Then try to start it normally.  If it starts right up then the fix is to replace the fuel pump.
