I have a problem that's driving me nuts

no one knows anyway it seems like.

 

sorry to piss you off man honestly I just need to know where the constant power comes from? diagram is not showing this

 

I'm not pissed off. And I'm also not obligated to help. You've been a mechanic for 20 years bud, you'll figure it out.

 

so turns out jumper wire isnt working again lol

 

since you dont know how to fix this how about we figure it out together then you can help the other two people with same problem also......like an ego booster

 

Or maybe no one wants to deal with tantrums.

 

is there a fuse between the starter relay and the starter?

 

no he doesnt know but i dont either so....... lol

 

Did you pull the fuse box, carefully and patiently, like Shifty suggested? If AM1 is a fuse, in the fuse box, and isn't getting power, then maybe one of the wires feeding the fuse is corroded or chewed through or whatever you could imagine. If nothing else, it will give you an opportunity to rule something out. Or, best case scenario, you find your problem.

 

Diagram shows constant power:



Looks like there is one fuse upstream of AM1, the 120A ALT fuse. Is that fuse working? Same advice from Shifty still applies: if the 120A ALT fuse is in good working order, then maybe the wires feeding it are bad and pulling the fuse box will help you deduce what's going on.

 

Sorry guys for being such a d*ck! I was frustrated

 

Hopefully you didn't leave that wrench sitting in the valley there

 

My thoughts exactly @shifty`

 

I thought it because I’ve done it

(albeit not on this vehicle, yet)

 

I saw that too but had stopped responding to this thread. Kinda chuckled to myself when I saw it. Looks like OP might have bought this truck and is now in the process of fixing the can of worms.

 

Yo I want my 3minute back from reading this bullshit thread lol

 

If a solid jumper to the starter isnt working, what about the ground wires? Sorry, i cant decipher the wiring diagrams either & will beg these folks to explain it to me like im 5, when the time comes.

 

Nobody on here wants to hear, "this is one of those parts where you really need to use Denso, because store brands not only last 2-5 years max, but plenty are straight-up DOA, or die within weeks".

We have to tell people this regularly. You're one in a dozen or so who've gotten shit parts-store-brand starters and had starting problems recently. They often come up as "truck won't start ... it's so weird, I literally just replaced the starter a few (weeks/months) ago because it wouldn't start ... maybe the starter wasn't the problem!?"

But when you say, "Naw. The starter was likely the problem. The shitty ass store brand part you bought is now the issue", the skepticism is high. Nobody wants to crack open the top end again to do that work, or fork over more money for the Denso/OEM part.

We've seen it. Way too often. I love linking people back to threads like this so they can see we're not full of shit, it's a legitimate problem.

And this is how we arrived at the rule of thumb: If the part takes more than 1-2 hours to replace, and you need to really dig and/or put in extra effort to pull it, always use the OEM brand, never use store brand parts. Your experience is EXACTLY why. OEM lasted 15+ years. It'll last another 15+.
