Blazer Won't Start

This is my problem, can anyone help?
My Blazer stalled out, & now will not start. It origanally started to run rough & then smoothed out fine & then I shut it off & now it won't start at all. I have replaced the fuel filter, all 3 relay switches in the glove box, control module, coil, & still nothing.
I have plenty of juice & I even had it started once by jumping the fuel pump hotwire under the hood. Now it won't even start doing that. When I turn the key on I get nothing at the fuel pump, no noise of operating, I have noticed that 6 fuses in the fuse box are now dead, not blown, no power, no directional signals now neither, never had a problem with those before. This truck has been in the dealers shop at least 8 times for various recalls & service. This truck is driving me crazy & soon will be past tense unless I can finally get a grip on all the service problems. Can anyone help?

Since you didn't list the year of your vehicle, I had to check your profile to get the vehicle information.
When you turn the key to the on position does the SES light come on?
Can you list the fuses that dont have power?
What you may have is a bad ignition switch...but before you go and replace a part yet, lets find out more info.

1997 Blazer 2 dr., 4wd, 4.3 throttle body
No lights on dash = abs, airbag, nothing, no turn signals, but, do have 4 ways. I was checking connections under hood earlier this morning all seem to be tight & no corrosion. While just standing there reading book & ignition on, doing nothing, everything came back & truck started everything good, shut it off & back to same problem.

This situation is actually pretty easy to diagnose. Trace the dead fuses to the fusible link that feeds it and fix it. The difficult part will be locating the reason the link blew in the first place. You will have to follow the circuits on the link to locate the source of the short. It is likely on a system that doesn't work, but it is not likely that you will be so lucky. Ray

By looking at the schematic, the turn signals,sir and the BCM are all powered by the same circuit from the ignition switch.
If you have battery power from the large Orange and 2 RED wires going into the switch and nothing on the Pink coming out..than the switch is bad.

Thank You GM Merlin, put in the ignition switch & everything came back truck started righted up

Good deal!
Glad to be of assistance. :)
