Hey guys, so my battery died yesterday.. had to jump it then i bought a new battery. I then lost driver side window and locks. so i took off the terminals for 10 mins and fixed that problem. today i wake up go for a run, come back and try to start the hummer nothing. no power anywhere.
i checked the terminals. leads/clampson super tight and getting power to the cables. ground is good, checked every fuse, everything is good to go there. made sure all the connections on the fuse box are good to go. and it is. so only thing i can think of is the ignition switch.. so i ordered one. will be here tomorrow.

Any other ideas?

 

I'm always a stickler for systematic testing.
* Are you running a brand new battery (i.e. from a store)
*Are your battery connectors OEM
*Are your ground connections clean and tight where applicable
*Are you in park
*Are you getting chimes, cluster and interior lights
*Are all fuses tested with ohm meter or equivalent method like test light
*Are you certain your fuse box is completely seated
*Did you jump the H incorrectly
*Did you check your main master fuse/fuse able link if applicable
*Is security system armed and not letting H start

Good luck.

 

* Are you running a brand new battery (i.e. from a store)---Yes
*Are your battery connectors OEM--- they are, was thinking about picking up some new ones and putting them on just in case
*Are your ground connections clean and tight where applicable ---- yes, took them off cleaned them up today.
*Are you in park---- i am in park
*Are you getting chimes, cluster and interior lights-- no lights at all, everything is dead
*Are all fuses tested with ohm meter or equivalent method like test light, yes everything is good to go.
*Are you certain your fuse box is completely seated--- yes made sure of it.
*Did you jump the H incorrectly---- no, just a normal jump
*Did you check your main master fuse/fuse able link if applicable. is this fuse 91? if so, yes
*Is security system armed and not letting H start- from my under standing the dash lights would still come on if this was the case correct?

I searched youtube and forums all day today, figured i would post here anyway. went through the steps. Once i get the ignition switch ill report back
Honestly though ill take and advice you guys throw at me!

 

Do the interior lights come on when you open the door? Headlights, parking, gauge background lights, etc? Or do you have absolutely no power at all? If no power at all then the main Maxi fuse.

 

No interior lights at all. i check the main fuse still has power on it.

 

ill buy a new one and replace anyway. they cant be that much. and try it out

 

so update. its not the ignition switch. im getting the mega fuse tomorrow and new batter cable end things and if thats not it then im throwing in the towel and getting it towed to the shop...

 

you could jump the main fuse with a regular fuse or check it with an ohmmeter. it should show a short. its like a piece of wire.

im betting its good...

sounds like the fuse box is not connected.

 

yeah i did its showing power..

i also took the two grey modules off the bottom and inserted them by hand before i put the top tray of the fuse box back on.... i was really hoping it was that first too..

only other thing i can think of is a ground some where i missed. so first light im going to re check it..

 

For Good measure I'd replace battery again. Also I'd make sure you connection to pcm were solid. Is the starter shorting to ground???
