Thread: Flashing Security Light and car stalling after a few minutes

So I bought a second GTP (2001) that was more modded than mine (2000) with the intenet of swapping motors and selling the second GTP. The second car has a L32 swap, XP cam, Intercooler, etc. I finished the swap (including computer for the tune) last night and started the 2000. It ran fine for a few minutes then would shut off. I would start it back up, run for a few minutes, then shut off. All this time, I have no check engine lights and only the security light is flashing.

My questions are these: Is the coded key/ignition locked to a certain PCM? What would I have to do to make the 2001 PCM work in my 2000...switch the ignition cylinders in the steering column?

Thanks.

All you should need to do is relearn the key. Although it's odd that it ran for a few minutes before stalling. Typically the security system wouldn't enable the fuel pump and injectors after the fuel prime at key on. You may have other issues.

How much coolant did it take after the swap. Anything under 2-3 gallons and it's likely air bound and heating up.

That's a possibility. It only took a quart, and I know that's not enough. How would I go about filling it? Remove the t-stat housing and pour coolant straight in there?

As an "oh **** thought"...could I have hurt the motor?

Relax..pretend I've "seen" this one before which is how I picked up on it. Motor is fine..

yeah pull the T stat. It'll likely chug down a gallon or two like it just came out of the desert.

No just take the rad cap off and fill till it doesn't suck anymore in and the level stays at the neck. Then fill up the reservoir and be done. Then bleed the system.

Or do whatever bill says ^^^ Lol

There's an occasional air pocket that requires you pull the thermostat. I've only bumped into it about 2-3 times. It's a real pain when you don't pull the t stat.

Drilled T-stat and that air pocket wont ever be an issue again.

That's what you say. I wish it were true.

John...it should start, use up the prime fuel and then stall.
