No crank, loose coil 2002 blazer help
Hey George, quick question before I do anything to this, do I need the plugs plugged into the NSS if I bypass it? I was just gonna jump the plug with a piece of wire will that work? Aside from the purple wires

Man this wiring circuit is a mess across multiple sources. Does your C2 connector have the same position and wire colors as your diagram in your last post? If so then yes I believe that you need to short E/ppl-wht to G/yel. If the back of the connector is open then you can back probe the connectors. Another approach is to release the pins from the connector with a small scre driver or a special tool for this.

That diagram I posted is the exact pin out on my truck I just replaced the NSS and soldered two new connectors on it there I just can’t adjust the nss itself because I have another starting issue, like I said, if I can get the nss out the way till I can move onto test the next thing I am pretty sure I got it narrowed down to the ignition switch like i said but not 100% sure. I should be able to buy an ignition switch tomorrow and it needs a shift cable if I can get both those tomorrow I will. I only have enough to get one or the other till Friday
Hey bud I haven’t put this off been busy and waiting to get paid sometime today I’m grabbing a ign switch for her, I am really hoping and praying it ain’t more serious because she is acting really weird sometimes it don’t wanna start it fires almost like it is out of time chug chug and won’t run, if I flick the ignition and play with it a little it eventually fires up and runs normally I REALLY need tools and parts I need a scanner, I really want to see what it’s doing, I have a multi meter but I need someone confident on the ignition while I am under the hood to check voltage and whatnot but the only person is only available every so often so hopefully after I get this ign switch in and grab a shift cable I can have my little brother jump in and help he is good and knows his ****, I can do the ign switch, cable I need his help and then back to adjust the NSS and HOPEFULLY fingers crossed it will fix it if not just another puzzle to work on
Oka y I put a new ign switch in works fixed ALOT of issues, but still no crank I know I need to adjust the NSS next to hopefully get it to crank at key, I’m going to bypass it to make double certain that’s the issue, now the shift cable needs to be replaced and I should be 100 no DTCs and everything working as it is supposed to fingers crossed, if that’s all sorted next will be going and doing ALL FLUIDs changes and filters, plugs and wires and take care of the cosmetics and add human comforts stereo, electric leather seats sand and paint the troubled areas… I’m excited hopefully George, this works, I need parts I searched all day no parts store around me stocks the shift cable imma order it online
New ignition switch, new NSS all wired up , new shift cable NOW I NEED someone to help me adjust the NSS so I can get it to turn over at the key I just finished installing the new shift cable tomorrow I need someone to help me at the ignition while I am underneath moving that switch til it turns over .
Well George, Thank you! Your help/procedure was INVALUABLE !!! I got the kink worked out i went back to square one and started tracing wires found a bunch of damaged ones fixed them, then as I am going through the UHFB I discovered the smoking gun one crank fuse had power on one leg but not the other pull it replaced it and guess what she fired at first crank AT THE KEY hasn’t started normally in a month or two now it cranks and starts every time at the key no more start button and it’s all back working properly THANK YOU
