try cleaning the chip contacts on your key.

it does it with remote start too

As I understand it, with remote start, the key would already have to be bypassed with a resistor, so check the wiring for the bypass.

jamilz28

ok i am stupid

can you explain what to do in a way that i can understand

What rob means is for the remote start to properly work you will have to either have the vatts (passkeyII) either tuned out of your pcm or you will have to do the vatts bypass. Robs site has a great write up on bypassing the vatts system. Check out these 2 links.

what the Vatts (passkeyII) does is it dissables your fuel pump and starter if it does not see the correct resistance from the "chip" on your key. This stops people from hotwiring your car if they try to steal it. the only way to crank the car up with the vatts working is to have your key (the one the vatts module is programed to" in the ignition.

I would suggest just following robs write up on bypassing the vatts. Or you can spend the $$ and have it tuned out of the ecm.

I would not be suprised if he finds a resistor once he pulls the panels off under the column, I had one like that, i just had to solder the resistor in, and never had any more trouble

oneslowz28

yes rember to solder it in. anything but soldering it can cause rf noise and / or a diffrent ohm reading thus sending a false signal to the vatts module and throwing the security light and dissableing the car.

jamilz28

can pcm for less or madz28 tune it out becuase i will need a tune soon anyways

Dave89IROC

yes it can be tuned out, and you will need to ground 1 wire in the dash

yes

oneslowz28

yes it can be tuned out.
