Do my gmc g2500 have starter fuse

I don't know model year? I looked at 96. You have a starter relay, there is a fuse that supplies voltage to load side of starter relay.
I didn't post diagram because I wasn't sure of model year? I don't know if the wiring diagrams are all the same on this vehicle starter circuit?

My 2003 gmc savana 3500 has a problem on starting. i change the battery and still had the same problem. So i decided to change the starter but stil no crank at all. Before i change the starter i just had...

Hope you can read diagram. Make sure battery has a full charge.Not only check the fuse, check the fuse circuit for voltage, use a test lite. Also, check the fusible link. You could use a remote start button, they sell them at auto store, Hook up the leads correctly at starter solenoid. Hopefully the leads are long enough to get you out from under the vehicle, the leads on mine aren't that long. Then you hit the button to see if starter will crank the engine. If you try something like that, make sure tranny is in park or neutral and parking brake is set.
The engine isn't froze?
I can only help with testing.

I have a 2003 gmc sierra duramax diesel and im in need of a glow plug diagram?

The diagram is simple each glow plug is connected in a series circuit like this -0-0-0-0-0-0-0 that's a in-line 6 for a V-8 it would look like this
and the plugs would be hooked up on the back then if you follow the wire to the glow plug relay you will find that the relay has four wires one to battery one to the glow plugs one to the ignition switch and one to ground in the box. If you want you can purchase a manual for 5.99 on-line. and it covers the three fuse-able links for this system and the new Glow plugs available for this truck here is the web page.

The glow plug system does not operate when you turn the key on

Go to your local auto parts store and look for a book, Haynes Diesel Engine Repair Manual, Part number 10330. It has your wiring diagram and a lot more. I got mine at Canadian Tire.
