Question about 2003 GMC Savana

2 Answers

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 to crank it 3 to 5 times and it start.now after intalling new starter the problem got worst so we decided to check some fuse and follow some instruction reset and when we install the battery with the key on and it was on on postion we had a ghost start just keep cranking so we turn off the engine repeat the procedure but it end up busting the ignition fuse and still no crank at all

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.

My guess is that you have the wires on your starter improperly connected, and they shorted out, and caused the starter to crank the engine. You have to be very careful when removing the wires. Make sure they are pointing exactly the same way as they were origionally when you re-install them. It is very possible , now, that you may have burnt the fusable link in your battery cable, and you'll have to replace it.

ITS part of the alternator. Check it directly at the alternator if u can. It sounds like an alternator starting to go. Have it ckd if u can. It should be reading 14- 14.5 volts at the battery.
