okay... so Ive been working on my truck about a month ago or so. I threw a rod. I got another 350 in, But. I dont have power to Anything at all..

I used a fuse checker. and It doesnt light up on Any fuse on the fuse box..
What can the problem be?
 
do you have the battery hooked up, ground and hot. Did you put the fuse able links back on the battery post of the starter.
 
ok i got that fixed.. But now the starter still has no power. I have two wires connected together with an eyelet? And that connects to the pos. Cable. ANd now i have the purple wire ran to the s. Stud on the starter. What wire connects to the R stud.? Theres an extra wire. I tried hooking it up bt the starter still wont power on. I hve pulled the starter and hooked it straight to a battery and it spins s the starter is good..

The battery cable hooks to the large diameter stud on the starter. Ther is also another wire that hooks to that SAME stud, and that wire (forget what color) runs up to a junction block on the firewall.

The purple wire hooks to the smaller stud. This is what sends power from your ignition switch to engage the starter.

If you don't have that other wire hooked up to the same stud that the POS battery cable hooks to on the starter, then your truck won't have power, as this is the wire that provides it.


Hopefully that helps!

yeah the wires are dirty and faded... But i have hat wire hooked to the stud of the pos cable. The purple wire hooks to the s. Small stud . I have that hooked up. But no power. What wire connects to the R stud? Or do i need it
 
OK, the two red links should be hooked to the big terminal along with the positive battery cable.
The purple wire hooks to the small terminal and goes to the ignition switch.

There should also be a short connection between the solenoid and the starter its self.

When you put power to the purple wire the solenoid should fire and supply power to the starter.

You could try touching a wire from the battery cable to the small terminal to see if the solenoid fires and the engine turns over.
 
Hi and thankyou again Fordum. You have always been a lifesaver.. there are Three Red wires , I dont know where the third goes also what do you mean by there should be a short connection between the solenoid and the starter. can you please explain to me. so that way if Its not there, I can put it there
 
I'm betting all three red wires go to the same terminal. The one the battery hooks to.

Now, how to explain the solenoid/starter hookup?

Even if you could see pictures, I don't have one to show you.
Basically, there is a short heavy piece of copper that comes out of the top of the starter in the back, and lines up with a short stubby terminal on the bottom of the back side of the solenoid.
There is a bolt that goes into that terminal through that piece of copper that ties it to that terminal.

It has to be tight, but will wring off if you get too enthusiastic with it.

When the solenoid fires, it hooks the battery cable terminal on top to that terminal on the bottom thus supplying power to the starter.

Maybe that makes sense. Look for that piece of copper on the top of the starter motor at the back. It should come out through a rubber grommet.

It may be a flat heavy piece of copper, or a piece of heavy copper braid.
 
Yep, perfect.
Hook the battery to that big terminal along with the red wires, and the purple wire hooks to....................

One of the other little ones.
And I am darned if I know which one.

Its been about 5 years since I worked on a GM starter, and I don't remember which terminal it was.

Probably the hardest one to get to.......

Somebody here should chip in sooner or later. There are guys here who have probably done one in the last few hours and they will remember.

But, like I say, briefly touching a hot wire to one or the other should show you. When the solenoid fires and the starter tries to crank the car, thats it.

Yeah It connects to the terminal with the "S" near it. But I connected it, and It does not Crank I hooked it up to the Battery directly, Grounding the starter. and connected a wire to the "s" terminal and the starter engages. But when I hook up the wires, and bolt the starter on, It does nothing.
 
OK, next thing to try, bolt everything on, hook up all the wires, and then, being darn sure its out of gear, try jumping from the battery terminal to the s terminal.

If it cranks, then you need to start checking why the ignition switch is not supplying power to that wire.
Blown fuse, safety switch, all kinds of things.

BUT, if it does not crank that way, then you need to start checking your grounds. Your battery ground has to be making contact with the engine block somewhere to supply ground to the starter.

Okay, I have my Battery ground Connected on the Alt. bracket. on the block.
and iguess Ill go out rightnow and Hook it up and see what happens.



edit: also the Purple wire should be a constant No? Or should atleast have power While the ignition is on? if so Ill test it with a tester. to save time and hassle
 
NO, the purple wire should only have power when you turn the key to start. Putting power on the purple wire is what turns on the starter.

Constant power on it would have the starter running all the time.

okay so if I turn the key on, and use atester. it SHOULD light up

is what im getting at sorry
 
I just hooked up the tester to it. I had a friend Turn the ignition to the On position And had him turn the ignition like the Truck would be starting. and Nothing. No light on the tester.. Where would the Fuse be for that wire? and where does that wire lead to from the starter?
 
Right. Turning the key to On, nothing will light up. But, when you turn it on over to start, you should have power.

Remember, there will be some kind of safety switch in the circuit.
If its an auto tranny, it will have to be in park or neutral to work, and if its a manual, the clutch will have to be pressed down I'm pretty sure.

Which means, if it does not work, you will have to check those out too.

I just dont see how the saftey switch could go out, It was working before I pulled the motor. It's an auto
 
Actually, don't know that it has. Just saying that if the starter doesn't work, that would be one more thing to check.
