02 Trail Blazer no crank problem and my solution 

Thank you soooo much, just bought the same year and nodel that has the same problem. I replaced the ignition cylinder because the person that sold it to me though that was the problem, so they removed it and never replaced it. I was told that was the only issue I had . So I took my chances and paid $350 - I will try this tomorrow.

Here in 2024! Im a car chic, thank u soooo much! Had replaced ignition swtch and still nothing. Checked wires and they were goodI put my shift in nuetral and it sarted right up! I

Y’all really helped me out I put my truck in neutral and tried to start it and it started.

Right on man great video you're spot-on with all your advice and thank you for telling me the size of what wrench to grab before even messing with the vehicle. Keep up the good work

Hoping mine is as simple as this. Thank you!

I have the same car an I was driving an it turned off randomly now it won’t crank I will try this today wish me luck compa

I have a 02 trailblazer and some of my fuses work and some do not on the fuse panel they are all good. My starter relay has power to two of the entry points Chris cross of each other- bottom left and top right work. What do I do?

No help here, but I'll take a closer look tomorrow for a cut wire. It's gotta be something like that, I replaced the starter the relay the ignition switch, got a replacement battery(walmart warranty ftw), it's gotta be a wire somewhere....but where?

I have an 03 Chevy travel laser. Just did the spark plugs on it 6 spark plugs when I change them and put the new ones in? It cranked up started up I took it for just a reverse test drive and it was missing so I turned off. The engine switch to a couple of engine coils around and it's still as misfiring. So so I ended up putting the old spark plugs back inside And no it does not want to start a crank's but no stuff so I put the new spark plugs back in and it's still not starting do. You know why

What do I do if I turn the key and I hear a clicking noise in the motor area.

That’s my truck!! You stole my truck! WTF!

I'm starting to think GM/GMC built in a "20 year PCM/BCM computerized logic-suicide programming switch," to make multiple systems fail. When you have all these modules, it is easy to electronically trigger a failure. I bet most of the people with issues, have the old onstar system as well. Look: 2022 -2002 = 20 years; these vehicles came off the assembly line in 2001...

No mames guey hahaha
