Probably a bad fuel pump, not uncommon.
1998 chevy blazer wont start good spark and good fuel presure

look on your fuel rail near the motor there is a bleeder to remove the air
fuel pump relay?
Set fire to it!
Because it hates you!
There is actually a little bit more info needed: 2WD OR 4WD, Ring Gear size, 7-5/8 or 8-1/2, What ratio? GM option code: GU4-3.08 GU6-3.42 GT4-3.73. However It wont be a direct fit to a 2000 blazer only 1995-1997 Blazer only. For 1997 makes a difference with or with out AWD, along with with or with out ZR2 option.
did you check your battery and alternator?
I've got a better question, why is this question in the Chevy venture forum ?
unless ones put in for racing or offroad it wont have one.
There has to be more information before the question can be answered. Does the engine crank when the ignition is turned? There are three things an engine must have to be able to start. You must have fuel, fire, and air. If one of those is missing then it will not start.
