Remote Start, 2001 Chevy Tahoe

I cant let this thing BEAT ME!!!! Haha!

BTW: I do have the 1250TL fwiw. The only reason I gave tachless learning a try is cuz the crimestopper RS I installed in my truck a few yrs ago worked without any issues that way.

Im in Wayne........Alright cool! I'll probably take you up on that offer if things dont go right.

the ultra will honk when a system reset is done and the horn out put wire is hooked up, thats normal. Does the truck crank each time it tries to start? How is the 555lw hooked up are you using the orange wire from remote start to trigger it? does the 555lw have power and a good body ground? And yes the white in the gauge cluster has always worked for tach. The tachless on the ultras leaves something to be desired. 

the ultra will honk when a system reset is done and the horn out put wire is hooked up, thats normal. OK THNX!

Does the truck crank each time it tries to start?  YES, it sounds like it's started BRIEFLY until it turns off, then tries again. I know the 3 attempts part is normal I just dont know why it keeps turning off.

How is the 555lw hooked up are you using the orange wire from remote start to trigger it? I actually do NOT have the 555LW, I have the older version, I guess, its just a 555L. This is how its connected >  blk/yell = yellow (r-code bcm side), yell = yellow  **color on the left side = is for the 555L, the right side is the car color.**

does the 555lw have power and a good body ground?  YES

And yes the white in the gauge cluster has always worked for tach. The tachless on the ultras leaves something to be desired. OK, I'll take your advice and reattach the tach wire.

Im wondering if I shouldnt be using the RED / white wire as one of the constant 12V wires?

Jeremy: thnx for being patient with me!

Im not sure what happened to my post above I could swear that I posted ALL of the wire connections, I might of hit something before hitting the reply button. Anyway I was mistaken and just went out to dbl check the black wire from the 555L IS connected to the blk/orange wire in the passlock system.

Quick question: Before I go nuts wiring the entire thing up again and find out its a brain issue, can I hook up x amount of wires real quick to check if this thing works w/out all the other bells & whistle options?

Also have you guys ever heard of a 555L going bad or coming bad from the manufacturer? Before knowing I had one wired up in my truck already I had ordered one online so if you think its possible I might try hooking up the new one.

Thnx for you patience guys!
