Let me preface by saying... never again.
that said.

I was working on my sisters car yesterday installing a remote starter, the Unit is an Ultra Start, unsure of model # off hand. The bypass I intended to use was a Platform 6 (XK06) from bypasskit with the PLXR firmware.

Well, heres the problem, I disconnected the battery and made all my appropriate connections, including the bulb check wire. The Passlock wire I grabbed was the yellowish/white colored wire in the 3 wire ribbon harness coming off of the key cylinder.

Now when I went to reconnect the battery and learn the bypass all hell breaks loose. The fuel pump turns on, but the car just cranks and cranks and cranks, doesnt get spark. With the key in the "ON" position, the "Theft System" light glows solid on the cluster, it is not flashing, but on solid. I have tried doing the learn routine and it has not worked. Whats more, the GM dealers in the area have refused to look at it.

My questions:

1. Anyone know of what may be going on and how to fix it, or what the exact learn routine is?

2. If that fails anyone know how to remove the passlock system? I know thats a stretch.

Bonus Question: I was able to hook it up right at the plugs at the key cylinder, how involved is dropping that under dash?

Not sure how to correct your problem. But the only way to remove it is to reflash the PCM and take it out. Which will take some pricey software to do.

Couple of q's
Does it just crank and crank with just connecting the battery or do you have to press the button on the remote?
If when it cranks and cranks can you stop it buy pressing on the brake pedal?
Did you connect the engines tach wire to the remote start?
What procedure are you using for the relearn?
