Just jumpering the power across where the relay goes. I removed it and just use a jumper. Now I have swapped it (the relay) with another and no its not the relay.

Oh I also have the alarm or parts to it. Does not have anything on the outside but the chip on the inside has (Telit and the number is GE864-QUAD also has down at the bottom C E0168) Also have a puck that was mounted on top of the dash with (SIRIUS and SIR-3-3RCTMOB03) if that might help?

I did notice it was hooked in the OBD2 connector wiring for power? One wire has a 10 amp micro fuse the other was a ground/black. Don't know if this helps but its about all I have right now?

 

Were any of the Blazer OEM wires cut or were they all just tapped into (attached)?

So what we know about the starter circuit is that you have battery power to the relay and a good circuit from the relay contacts to the starter. Now lets find out why the relay is not being energized with the ignition in the start position. See if you get power to the crank fuse when the ignition is in the start position. In that state always hot power is routed from the ignition switch to the crank fuse on a yellow wire. If not, does the dash light up with the ignition switch in the run position?

Ok I will check tomorrow to see if I get power to the crank fuse when the ignition is in the start position. Yes the dash lights up properly and when I turn the switch to crank most of the lights go out and you hear a click like it should try to crank but wont.

Oh from what I can tell the wires are ok nothing was cut just tapped into.

Now also I have done the deal of turning the switch to on and tried to start it then back to on and left it for 11 min then turned it off for 10-20 seconds then back to the on position a total of 3 times then I shut if off and pulled the key for 30 seconds and put it back in and tried to start the truck. But I have noticed that the security light it working properly now. It will turn on when I turn on the ignition switch and then after about 4 seconds it will go out and the 4wd light is coming on in the 2wd position. Everything seems to work properly now except it wont crank? Just other things I have noticed. ;-)
