00' Grand Prix GT won't remote start

Ahhhh... young one..... Class 2 or not.... doesen't make a bit of difference. The GM passlock3 system is not databus dependant. The data wire that comes from the key reader is just that. A data wire from the key reader to the rest of the immobilizer. The fuel interrupt style of PK3 has the majority of the immobilizer up at the key, and it pulses to the ECM. A 2000 Pontiac Montana does not have the Class2 buss, yet has a "data" style immobilizer. A 2000 Pontiac Venture may have either "data" or fuel interrupt.... but no Class2 as well. The blue wire in the immobilizer harness is the tell-tale sign...... us old guys know to look for it before we prewire things on the bench..... Gus Wherever I go, that is where I end up......

Hee hee! Age and cunning will always overcome youth and vigor. BTW- Oddly enough I did a 2000 GP om monday. Used a 555G.     They're fuel interrupt. There's a blue wire. I checked before I prewired. It was in and out well within an hour. Gus Wherever I go, that is where I end up......

lol.... I'm with Gus on this one. Although I'm not an old guy.... yet, experience is the key.
