can a sepertine belt on a 87 blazer stop the truck from cranking

first,what kind of screw to secure belt,will run without it ,just no water pump, ps, alt, ac,dont want to run long without it.check to see if getting gas,spark to plugs.have seen this to remove air filter top rats nest in it.finally check dist,cap and coil .

Vehicle will only run without the serp belt until the battery dies. Serp belt controls the alternator which runs the vehicle once initial start-up is complete. Many vehicles have alternators which will not charge in the event that input battery voltage is not 12 volts or higher -- so a dead or low charge battery would not start the vehicle or charge itself. Need more information, put a new battery in and secure the serpentine belt properly and post the results.

first off do you have any power and if so does it make a clicking sound cause if it does then cheack all the connections to the battery and the the battery will probably needs to be charged but who knows with out looking at it but thats what mine did so hope it helped ya ...
