I just did a remote start on a 98 Buick Century and it looks to have the vats security.
I have 2 white wires in a grey tube and the resistor in the key. I also have a green and a brown wire seperate frome the others for the key chime.
I cut the 2 white wires, installed the key and checked resistance. 887 ohms. Ok, I purchased a resistor within 1 ohm and just twisted the wires across the car side of the two but didn't hook up the key side at all for now. I will wire a relay later.
I started the car with the key to make sure it ran. It did.
I then started the car with the remote and it doesn't crank. I did it again and then put the key in and turned it right before the RS cranked and it started fine.
What am I missing? I even jumped the 2 , brown and green and it activated the key chime incase it was a key sence or something.
Or does it have to have one wire connected to the key side of the vat wires?

sounds like you might be missing an ignition wire. Pink = ign. 1 white or green = ign. 2 yellow = starter orange = accy. double check to make sure you have all of these connected. also check to see that the remote starter itself is putting power on these lines at the appropriate time.

yes. Pink,white,and orange are hot in run.
brown is hot in run and acc. But I jumped power to it and the radio came on so its acc. Pink and white are hot in crank. I will double check tho.
And yes yellow is crank and hot by RS crank mode, but it doesn't crank. Unless key is turned to run after I hit the remote.
This is with the 2 white wires cut and the resistor closing the vat side.
Thanks for the reply.

Don't know why you cut both White wires. You could have checked Resistance on the Key itself
You only need to cut 1, hook to SPDT ( Single Pole Double Throw )Relay, with Resistor & put one end of resistor on other uncut wire.

Well, thanks for the advice... I had the orange acc. lead and the white 2nd ign. lead crossed on the RS.
The starer has a delay for the acc. , about 2-3 seconds. Enough to make the system not crank. I put a jumper across the two to test and it fired right up. Then corrected my mistake.
Thanks again.
