HELP! GMC Sierra Ignition/Fuse Issue

9 posts in this topic

1999 GMC Sierra Ext Cab 4x4 5.3l, about 203,000 miles on it.

OK... Drove home from work today, truck was running fine. Parked in the driveway, went in and changed clothes, grabbed my muskie stuff and away I went. Wrong!

Turned the key and nothing. Nothing! No starter turning over, nothing.

Underneath the hood, in the fusebox, I have a 40amp fuse labeled 'Ignition' that was blown. Picked a new one up at the auto store, popped it in, turned the key and blew the fuse again.

What the heck is causing that fuse to blow?

One minute, truck is running and starting absolutely fine. Next minute, its blowing this fuse. Grrrr....

Any ideas?? Now I gotta figure out how to get to work tomorrow. frown

Hanson:

Don't know if you have this figured out yet but my first guess would be a shorted out starter. Did it turn over at all after you replaced the fuse?

Second guess would be a shorted alternator. If your inclined (sacrifice another fuse?) you could losen the belt and rotate the alternator half a turn & try again.

Nope. Never heard it crank at all.

Chris, it looks as though the main draws of this circuit are the starter relay, and a feed to the ignition switch that are all fused seperatly. I would remove the starter relay and see if the fuse will still blow, if it doesn't you know it is in the starter circuit. More then likely, a bad starter.

If you want a wire diagram let me know, I can email one over to you.

I started with the starter, pulled it out and brought it over to my neighborhood O'Reilly. They ran a test on it and it passed twice. Starter and starter solenoid aren't the issue.

Now I got to put that ******* back in there. Engineers I tell ya. frown

This problem is really ticking me off.

Well... she's running now. Nother mystery of the universe.

Best I can figure is I have a dead spot on my starter now that caused that short. Like I mentioned, brought it into O'Reilly and they ran a test on it, worked fine. Put it back into the truck, popped a new fuse in the panel, turned the key and she fired up. I've since restarted the truck about a dozen times with no issue. Go figure.

Only other thing I can think of is I disconnected the battery before I removed the starter. Not sure if that reset something or what but I'm currently in business.

Guess if it happens again, I'll probably just put a new starter in it.

Uggh. That's one of those pucker problems where you pucker every time you hit the key and hope it fires when you're away from home because you know in the back of your mind that you really never found the problem.

Better carry a few extra fuses and a dead-blow hammer to give the starter a whack when it happens again. smile

could have been the starter solenoid pull back hung just a tad, enough to put a draw on the circuit. Is the heat shield in place on the starter? also could be a wire in the steering column that got pinched and moving the wheel/shifter might have moved it a bit. If you let the truck sit overnight, before you try and start it, open hood and feel the altenator to see if it is warm. That would also indicate a leak however your not loosing power just popping the fuse. I hate gremlins. They stink

    • I've only tried them with Northern, but honestly, I'm not sure I could taste the difference if I didn't make them myself.  All psychological, IMO - this will likely start an off-topic discussion BUT I participated in an 8 person taste test between Walleye, Northern and Bass (yes, we cut-up a medium sized bucket-mouth).  I was the only one to name all three fish correctly and it was only due to the fact that my friend who was in-charge of the test accidentally missed a y-bone so I just had to guess in-between walleye and bass and I guessed correctly.  A couple of the guys also had a y-bone and got their guess between 'eye and bass wrong!!!  Flaky white fish is flaky white fish - especially when you bust it all up, mix it with bread crumbs, mayo and whatever else.  Again, just my opinion.
    •   I agree the split did not work out. Also a lot of people are on FB. Heck I finally joined last year. Jury is still out whether I like it or not!!
    •   Just like you being a social media queen, LOL

    • Every one said, with out Double here we may as well leave.   So, Welcome back may be with you here they will come back now! 
    • My buddy Dan and I have been going to the same farm for 3 years now and the turkey hunting is almost unfair. We've never been skunked and the only time we haven't tagged out is the first year.    This year the bowhunting was tough. We were trying to be fancy and get things on film and it hurt us tremendously. So, naturally, we gave up on filming and went back to having fun.    We shot 4 turkeys, a tom and a jake each, all by fanning (reaping). The action was intense and super fun. Additionally, after having a set busted by a wandering daytime coyote, I lip squeaked her into to 20 yards and finished her off with the same treatment, a load of #6 to the face. My jake and the coyote are on cell phone video so I will see about sharing those.   My tom, came on the last day. He ran more than 200 yds just to confront that turkey fan. Due to a depression in the landscape, I had no idea where he would come up. He emerged at 10 FEET! and in a split second I shot him at 8FEET!! Thankfully I had the bead on his head or I would've likely missed. Nothing beats turkey hunting with your best buddy.    And I'm having a taxidermist friend of mine do a euro mount on the coyote skull. Unfortunately the hide was shedding terribly and was matted with mud. 
    • Merriam hybrid killed in Nebraska 5/4/17. 
    • Bonus points!  Well done Andy.  
    • Now I figured out how to add pictures. Time to submit for a score. 
    • I think they got greedy and it backfired. Lots of ads everywhere, requiring subscriptions for some forums. They split the boards up into two different websites (fishing MN and HSO), the boards went down for a while, and most the traffic got fed up it all and just moved on. I used to check this place daily, now maaaaybe once a week.
