2004 Colorado remote starter

Following instructions from the directech site I started my truck then cut the blue / YELLOW wire and measured the resistance in the crank position. I got about 3K ohms so i shut my truck off. Out of curiosity with the wire cut I attempted to start  the engine and it cranked right up. So whats up, I mean the key was in the ignition but I cut one of the key sense wires. Im new at this but there are 5 wires coming out of the ignition and the directions are quite clear

How long did you wait before restarting?Did you HOLD the Ignition Key to the CRANK position while measuring Resistance?MO

There is none....that was back on Passlock systems in the 1996-1999 era.

I have a colorado and there is no Blue / YELLOW.Did you mean WHITE/ blue data wire.colorado tap the rockies

Ya, it is WHITE/ blue sorry

Ok between 78 musicman and mo12v Ive got my viper 771 wired, tach learned, and cranking with the 555lw bypass installed. But,  I get about 3 seconds of crank the engine starts and immediately dies. This is a self learning unit but the truck is a hybrid passlock 1 and 2 and I have no specific wiring diagram to go by. I have cut the ignition WHITE/ blue and interrupted it with the 555. My problem is I should be using the WHITE/ yellow for a reference wire according to directed doc 1603. My truck will not even crank or run like this even with the key. If I connect to the black passlock ground input from the 555 to the black in the ignition harness my truck starts and runs normally.

Do you have the ground out from remote start wire hooked to your bypass?It only grounds during remote start.Its hard to get what you are saying.Sounds like the bypass is working or it will not crank at all,but your R/S is shutting it down.colorado tap the rockies

no it goes to the chassis ground, the bypass wants the passlock reference wire connected to its black except I dont have a black reference wire in my harness.

555L doesnt work on this chassis... you need 556L or PLJXKevin Gerry
