2000 envoy no start - electrical problem

Okay here is the scoop a 2000 GMS envoy (build on jimmy chasis slt) was working fine then all of a sudeen one day it will not start- NOTHING .. key get stuck in ignition switch but to get key out if i put on a battery booster 55 amps key comes out. I hear clicking in teh dash ( relays i guess) but there is no electrical power at all .. will not start with booster on it either?

Can it be a relay?
is the fuse box maybe not putting out 12 volts? (how would i test it)

Any ideas anything to jumper or test ?

I have checked all fuses they seem fine... one fuses blows each time I put booster (battery starter) on it.

It has a remote starter and that won't start truck either? - could remote be dead? is there a safety neutral switch?

Any help would be great it sitting stuck in my drive way !

Sounds like it just might be a bad battery. Try a fully charged battery in place of your old one.

Nope there seems to be NO electrical to dash at all, even when I try to boost it it will not start - no lights nothing inside!

Get a good volt meter.
Charge up or replace battery.
A dead battery or bad batery cabels will will not take a boost.
and then check for 12-13 volts to underhood fuse and relay junction box.
Check both sides of big fuses.
Does it have good voltage on everything there?

If thats a aftermarket remote start, which most likely it is(could be wrong though), take a close look at the romote start unit. There could be something wrong with it and causing the problems you are describing. But first as others have mentioned, check the basics first, make sure your battery and connections are good before going to far into it.

Thanks folks .. appreciate the help!!! turns out it was just a bad battery!
