Question about Chevrolet 2500
04 chevy 2500HD with 6.0 LS style motor. When turning the ignition key to the crank motor (start) position, I get a quick click sound then dash lights, interior lights shut down as if a fuse has blown. Then within a few minutes dash lights, radio, and interior lights work again (as if there is a heat related circuit braker). I can try to crank/start the motor and the process starts over again. I could not find a blown fuse for ingition and/or starter. Looked and the main under dash hub fuse in the engine compartment was ok. No blown fuses that I know of. Is there a fusible link and/or circuit braker for the keyed crank/start position? or may this be a problem with my ignition starter relay switch?
Make sure battery has a full charge and battery connections all good. Any fuses in the diagram, test for voltage, some are hot all the time, some go hot with the key on.
Use a digital multimeter across battery posts, everything off, the generic spec for a full charge is around 12.6 volts. Leave the leads hooked up to battery, have a helper turn key to crank, how far does it drop? In my opinion it shouldn't drop much under 10 volts, I wouldn't argue with 9.6 volts.

Doing starter circuit testing is the way to find bad connections or bad cables etc...Using a volt meter !
Starter Voltage Drop Plus you need to know what happens when you turn that key an all the parts that are involved in the starting of that vehicle . Starter relay's , transmission range switch , PCM .

Are you sure its the starter? did you try it in neutral? could be park neutral switch, or ignition switch, or if its a standard shift maybe it has a switch on clutch that it has to be depressed to start and its bad. As far as jump starting you cross the maine or big post on starter to small or little post on starter to do that, on a v6 starter it on the right side under exhaust manafold, and i think its on the same side on a 4 cyl.

Low voltage will cause the problem you are having,get the battery charged,and then have the alternator checked for the correct out put,13.65 to 14.25 if it is not in this range give or take a couple of volts,replace it,I would have the battery replaced also,so you won`t have the problem again.Have a shop replace the battery,if you do it yourself,the memory could be erased if certain measures are not performed.

I would check the fuel pump turn key on do not start or turn engine over just until dash lights up and you should hear a grunt sound come from back seat area if you do not hear this grunt your fuel pump is not working.Also if you have a check engine light on you should have your can scaned with a OBD 2 scan tool to retreve and faults the cars computer might be undrer going.
