GMC Repair: GMC starting problem and starter removal, negative battery cable, cable failure

Question
I have a 96 GMC Senoma 2L, 4cylander standard truck that is giving me problems starting. I
went to town the other night for dinner, and it would not turn over when I got out of the
restaurant about an hour later. I got a jump and went home. The next day it started fine. I went
into town and came home no problems. Then about 20 minutes after getting home I had to go
out again and the truck would not start. The battery was replaced 4 mounts ago due to the truck
not wanting to start on cold mornings (problem fixed ), the alternator has been checked it is
good. Now my 15 year old son is trying to take off the starter to check it and it will not come out.
He has removed the two main bolts; and, their are no nuts in place that would have secured it to
the “V” shaped bracket on the radiator side. Yet, the starter does not move more than a
millimeter. It has been suggested that we remove or loosen the bracket; however, neither of us
has been able to find any bolt that is holding the bracket on. Their is a rather large wire blocking
the very top half inch of the bracket but I can not move it out of the way to see if there is a bolt
under it. What are we doing wrong? I am not mechanically inclined and my son is new to this.
Any help would be appreciated.

Answer
There is a nut holding the bracket on the rear of the starter onto th engine.

Starter Motor Replacement (2.2L)
Removal Procedure
Caution: Before servicing any electrical component, the ignition and start switch must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.

Notice: Never operate the starter motor for more than 30 seconds at a time. Allow it to cool for at least two minutes. Overheating, caused by too much cranking, will damage the starter motor.

Here are the instructions as per GM.

Disconnect the battery negative cable.
Remove the exhaust manifold pipe.
Remove the engine to transmission brace rod mounting bolts.
Remove the engine to transmission brace rod.
Remove the starter heat shield.
Remove the wires from the starter solenoid.
Remove the brush end bracket attaching bolt.
Remove the starter motor mounting bolts.
Remove the starter from the vehicle.
Remove the brush end bracket from the starter, if necessary.
