hi, i recently bought an 03 blazer 2 door and i'm brand new to this forum.. recently i was attempting to install a new deck and audio set up in it. i kept having problems getting the wiring correct so i think i got wrong wiring diagrams.. ugh. but main problem is that after i gave up i went to start it and it will crank and start up no prob with the key but dies as soon as starter disengages... i'm thinking fuel pump, or at least some sort of problem with fuel pressure. any ideas thought???
thanks a ton..

 

Did you do any wiring around the ignition switch? Sounds like maybe the ignition run wire "Ignition 2" problem to me.

Here's the colors on the ignition switch. The white wire is the one I think is the problem. It supplies voltage to the coil in the RUN position.

82-93 S-10 or blazer
12volts red (there will be 2) + ignition harness
Starter yellow or purple + ignition harness
Ignition pink + ignition harness
Second Ignition white + ignition harness
Accessory orange + ignition harness
Second Accessory brown + ignition harness

 

ok i think you might be right but thing is it's an 03 so colors are def differnt.. there's no white. i'm thinkin i need an immobilizer bypass module?? ugh confused..

 

ok so i played with it and figured out one of those wires were connected with the ignition switch. thanks a ton!!
