1997 tahoe won’t start

[jfromoutwest]

No crank no start , Horn blows when trying to turn key , pulled the horn relay and now it just clicks , power is going to the starter relay , and there is no security light on when the dash lights up .. any help ?

Horn blows?? That's a big red flag as I can't think of any system aside from keyless remote that ties into the horn. Does it have any aftermarket remote start or alarms? All power starts and ends at the battery so that's the first stop on the diagnostic train. Check power and ground to start with.

i pulled the horn relay so it doesn’t blow. when i turn the key now , all that happens is the radio clicks on and off and the fuel pump kicks on again

I think that is it , but could be my starter as well , i was hearing the bad starter click when trying to start it a few days ago.

think it’s something with the wires on the ignition switch , it started a few days ago ,shut it off , and then i was going to put the key in the ignition and accidentally hit the opening where the wires are and it didn’t start after that .

Just remember that the ignition switch and the key/tumbler assembly are two different things.

If you find its not the ignition switch, check the transmission’s manual lever position sensor and wiring leading to it (mounted to driver side of trans at the seldctor shaft)…if yours is ‘97 it should have a two-connector switch. One is for park the other is for neutral. If it fails, you will have a no crank/no start condition but all other functions will typically work like radio, power windows, etc…also try putting it in neutral to see if it will start…ive seen some of those things partially fail where vehicles won’t start in P but will in N…

Don't have any idea what wires you could get near while attempting to put the key in the ignition.
If you want to play the guessing game you're most likely going to replace a lot of parts that don't need replacing. It's time for basics and diagnostics unless you're a lucky guesser.
