Chevy Trucks, Blazers, S10 pickup and the like will vapor lock ecspecially the 2000 models. Do not tighten the gas cap past 1 click. There is a tube that runs from the top of the tank down and this gets hot and collapses or burns in half. We just bought a reinforced rubber tube cut it to lengh and use it instead of part and it's worked grat for 2 years so far.

Have they checked your TPS sensor as this is the most common cause for rough idles and stalls...

SOURCE: "Cranks, but won't start". Replaced fuel pump, CKP, ICM & nothing
If the engine
cranks over normally when you attempt to start you car, but the engine
does not start, the problem may be NO FUEL, NO SPARK or NO COMPRESSION.
The engine needs adequate fuel pressure, a properly timed spark and
normal compression to start.
1) To find why the engine won't
start, remove the air inlet tube from the throttle body, push the
throttle open and spray a small amount of aerosol starting fluid into
the engine. Crank the engine. If it has spark and compression but NO
FUEL, it will start and run a few seconds before dying. If it does NOT
start, it probably has NO SPARK.
2)Another method to check for spark is to pull a spark plug wire
off of a spark plug (if it has plug wires, coil-on-plug ignitions do
not) and place the open end of the plug wire near a metal surface on
the engine. Have a helper crank the engine while you watch for a spark.
DO NOT hold the wire while doing this as it can shock you. If you see a
spark, the problem is not spark, but most likely NO FUEL or NO
COMPRESSION. If you do not see a spark, the problem is in the IGNITION
CIRCUIT.
3)Proper fuel pressure is critical for fuel injected engines
to start and run. You should hear the fuel pump inside the fuel tank
buzz for a couple of seconds when the ignition is turned on (no buzz
means the pump is not running and the engine is not getting fuel). You
can smell the tailpipe for gasoline vapors after cranking the engine.
If you smell gas, the problem is likely not fuel but NO SPARK. You can
also remove the plastic cap and press the schraeder valve test fitting
on the fuel rail to see if there is any fuel pressure to the engine
(not a very accurate test because fuel pressure must be at a certain
level for the engine to start, for that you need a gauge). Even so, no
fuel at the fuel rail would tell you fuel is not getting to the engine..
