So I just picked up a 95 z71 with 160k, original owner, it ran very good while checking it out, drove it once, all good, waited a few weeks and went back and drove it again, all good...then i bought it...... all was good till i brought it home and the next morning, what do you know, problems already!

It seems like battery is bad but I just put in a new battery and still i get slow cranking...i posted a video to hear whats going on...any help is appreciated. Thanks

Just took it out for another drive, after the slow start...it runs very good, idles good as well....im thinking maybe starter or alternator, possibly fuel related...just wanted to get some opinions before i start replacing stuff i dont have to.

 

more than likely its the starter. A bad starter will also drain the battery but its a start

 

Your local autozone, Kragen or other have these things they can
Hook up to your vehicle and tell you what's wrong for free.
Be it battery, alternator, starter etc, they'll let you know.
Try not to be too mad at it.
These things are wear and tear parts.
My battery went out a few days after i bought mine. No biggie.
Fwiw I bought a battery with a buttload more cold cranking amps
Which really helps those cold starts on cold mornings.

 

try cleaning grounds and connections. Have the plugs been replaced yet? any codes?

 

no codes, no engine light, just passed smog today (yay!) ...cleaned grounds, replaced plugs,replaced fuel filter, added sea foam to fuel, new oil...cleaned carb with carb cleaner, runs a bit better but still has slow crank/start...will pull starter and have checked next weekend, gonna look for one at junk yard and rebuild it...see what happens.

oh, another thing, after taking off air cleaner i noticed that the throttle body looks like this, is it leaking/cracked or? is this normal? thanks

 

I used throttle body cleaner and simple green on mine and it made it look good as new

 

what did u do for ur leak int the tb. my 95 is got the same promblem. did u rebuild the tb?
