Just went out to move the suburban, and it wont start. It did this before about a week ago. Only two things that are similar are that it was really cold that night, and its really cold right now. Everything comes on, radio, etc. Plenty of voltage. Turn the key and i get a click. Not the click click click click you get with a bad starter. Just a click. Any ideas?
 
Check the battery cables(mine melted to the manifold once and shorted out, all it would do was click until i pulled it loose), terminals, and connections at the starter, they can be loose enough that they won't allow enough power through.
 
Last time we were in the dunes I went to fire up the k10 the morning of the second day and I got the same thing. A single click from the starter and everything else worked.
I got someone to get up under there and whack it with a hammer and it fired right off.
It's done it a handful of times since then but I'm too cheap to change the starter until it goes out completely. :)
 
It really does not sound like the solenoid is getting power at all. I know exactly what you guys are talking about with the whole nock the starter to get it to work. Not really whats going on here. This is just a loud mechanical click.
 
Battery is brand new. Its nothing simple. Not from my perspective anyways. I suspect its something electrical, fusible link or something along those lines. I just dont know **** about electrical in these newer trucks.
 
So i have a 98 with with the same issue have been having battery issues.

So wouldn't start for my wife went to go and look at it power just went click, no start

figured it was the starter 150000 miles could be, banged on it no go, hmm

$120 new starter lifetime warranty put it in, no worky hmm. time to get the bat. :mad:

So mine has a power going to the computer and one coming of the the starter both go to the battery.

One will power the everything else the other powers the starter, makes sense now, not then. The one that powers the starter motor not the solenoid wasn't getting any juice. So changed the ends to the cables well stripped of the rubber and now it works. Cables were tight too just the double cable wasn't getting any contact.

if you have the double one I would look there first.
 
I second the cables. Those cables are notorous for corroding from the inside out, with no noticeable wear/corrosion on the contacts/ends. Check the ohm load through the wire, or replace the cables. I bought mine from the dealer, cause i wanted stock style, but there are cheaper ways to go. If your battery has top posts, i suggest converting to top post style cables. Good luck
 
You may want to invest in a load tester. I had 4 batteries that tested terrible with a load tester but the voltage was good and they didn't suffer voltage drop when the key was hit.
 
Sometimes in my 98 Suburban the cables come loose at the battery and i have to tighten them from time to time. Sounds like a connection issue to me.
 
Ill echo the corrosion on the cables, check it, mine was inside the cable insulation as mentioned above on my 99 3/4 ton.
 
Actually I've had all of the problems listed above plus a bad ignition switch, bad ignition switch fuse in the box under the hood & bad starter.
I check battery posts, voltage, load test the batteries, check fuses & oil. I always check the oil when I pop the hood.
Then I try to jump start with a pair of 00 wire sized jumper cables & finally try to jump the solenoid on the starter. Usually by then I have found the problem.
