1998 GMC Sonoma 4.3 L Won't start!!!!

My 2 wheel drive Sonoma has about 95,000 miles on it, and never has has a problem before. This is a pretty wierd one.

I tried to start it today, and the dash clicked and the dash lights flickered on and off. It seemed like the starter tried to engage, but nothing happened. I figured it was a dead battery, so I flagged someone down with my jumper cables and we tried it. Nothing. It didn't even seem like the truck had power, the radio beeps like it is trying to come on, but it never does. Sometimes the dinger works to remind you the key is in the ignition, and sometimes it doesnt. I then had the guy try and pull start me, had the key on and released the clutch in second. The motor did not fire.

I thought maybe I threw my serp belt, but it is there and fine, so the alternator is turning.

The only thing I can think of is maybe my ignition switch is bad, this would keep it from starting and running, and also keep the radio from working....

I have also noticed that recently my windshield wipers don't always work, but this is probably not related. I checked all fuses and they seem to be good.

So in a nutshell: engine wont turn, lights wont come on, jump start doesn't help, pull start doesn't help, radio, beepers, and guages show erratic behavior. No sparky.

Thanks,

Ryan

I would bet the battery is bad and quite possibly leaking acid from the positive post.Replace the battery and clean any corrosion from the cables or better yet replace them also.

Okay, I can try that. The battery is only about 18 months old, though. I think it's still under warranty from Wal Mart so it should be free. Why wouldn't a pull start start the truck, though?

If the battery is stone dead you will not have enough voltage to run the ignition system.The alternator(actually the generator)does not charge the battery it maintains a state of charge because it needs 12 volts to operate properly.If you like have the battery tested I could be in error.How many volts does the battery have across the terminals?

Okay, it ws just a dirty battery terminal and cable. Scraped the junk off and it fired right up!! Would it have pull started if that connection wasn't dirty and the battery was just dead?

I don't beleive it would because everthing needs the battery(charged up) to be there to come alive.
