I've got a better question, why is this question in the Chevy venture forum ?
Because it hates you!
If the windshield wipers won't turn off on a 2000 Chevy Blazer, check the wiper relay switch. This is usually located in the engine compartment fuse box on top of the battery.
1998 chevy blazer wont start good spark and good fuel presure
Set fire to it!
did you check your battery and alternator?
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.
Probably a bad fuel pump, not uncommon.
unless ones put in for racing or offroad it wont have one.
Something is wrong with your 2000 Chevy Venture. Better information get's better answers.
check heater fan to see if it is working.
look on your fuel rail near the motor there is a bleeder to remove the air
take it to a transmission shop
