Getting ready to replace the altenator in my 93 blazer. Shouldnt be a big deal But the instructions show concerns about the tensioner. Not letting it snap back in place? Do I have to hold it back somehow. Whats the best way of going about doing this job. Im going to do this fix on the 6th of Dec. So if you could get back to me soon. Alt is still running but making noise like a banchee.

Re: Not a problem yet
What they refer to is not just letting it go and slam back against it self it is spring loaded and this would cause the stop to break off. just let it slowly release with your wrench until it bottoms out

2000 Chevy blazer doesn't have a carburetor. It's multiport/sequential port fuel injected.
Your injectors look like a spider inside the intake manifold. If they are not delivering fuel, that assembly needs to be replaced.
That's a pretty big deal. Need to replace a few other gaskets as well since other components will be pulled.
ALtenator runs your car while it is running and charges your battery. If your altenator is bad you car will run on the battery until it drains the battery dead. So no the altenator will not prevent you car from starting. Check your fuses.
I just had this problem. My mechanic found there was a male-female wiring connection to the starter which had gotten dirty over the years so there was a very poor connection and not enough current could reach the starter. He cut off the wire (probably like a 12 gauge wire; he showed me the part) and soldered on a replacement so dirt can no-longer accumulate and cause the same problem (if the starter goes I'll have to unsolder and resolder the wire, but not a big deal).
Measure the voltage at the big wire on the altenator engine off, do you have power? Check in your distribution box under hood, find the two rows of fuses located inside the box on the outer edge, look at the outside row from front to rear the 4th fuse (# 11/ 20 AMP fuse), is for the altenator field, make sure this fuse is not blown, if it is good and you have battery power on the big wire at the altenator, then replace the altenator. Hope this helps, let me know.
If you live in a state with smog license requirements your wasting your time, the engine has to meet EPA requirements for the year vehicle was manufactured your car is considered a clunker good luck getting it smogged. And it is no big deal to change. 350 is almost identical to 4.3 just some variations.
try yhe pickup coil or ignition module wich are both located on the distributor or the igniton coil.im going through the same thing.all i have left to try is the ignition module.if i get it ill be sure to let you know
