00’ Grand Prix GT won’t remote start

I have a phoenix digital car alarm/ remote starter pd-175. I have all the wires ran like I'm suppose to and everthing else is working on it but the remote starter. The only way it will remote start is when the key is in the ignition, but even with the key in the ignition it still holds way too long when it starts. Without the key in the ignition it only starts for about 3 to 4 seconds before it automatically shuts off. The only reason I purchased it was for the remote starter, I already had an alarm on it. I have everything else I need, I know I have passkey III, so I have the passkey III 555G bypass module and everything should be connected right. Can someone please help me with this problem, it would be greatly appreciated.

u need a bypass module for this type of car and the reason it stays cranking for too long... 3 things that it can be (1) tach is not learned (2) crank timing is set for too long and (3) voltage sensing is not on... it might be those things. but the car won;t remotestart without the bypass module.

I have the bypass module.....

does ur car have a class 2 data bus system?  a easy way to figure out if it does is to open the drivers door and turn on the headlights with the key off....listen to hear where the door chime is coming from....if the chime is coming from the drivers door speaker then u have a class 2 data bus system.

Where theres is a wire there's a way.

what diagram did u use to wire the unit up?  where did u get the diagram from?  IF it is starting with the key in the igntion then u know u have a bypass wiring problem.....and what do u mean by it hold too long?  where did u get tach?

What bloody difference does it make if the car has Class2 or not? He's doing a remote start... not a deck.

In the column harness, you will see the immobilizer harness. It will have: Purple, Pink, Orange, And a black wire. It will be taped every 4" or so with orange tape, and will terminate in a grey plug. Would there happen to be a blue wire in this harness? If so... it is a fuel interrupt system, not a data system. Follow the instructions on the 555G for "fuel interrupt", and set the jumper appropriately. This should take care of your peoblem.

the 555g has 2 different install types.....so that would prolly make the bloody differance ......

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.....

I love it.....

Ahhhhhh....young one......  Oh, and, us old guys    this is good readin

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.

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