Code P1629 and Code P1573

**gmsprincess** · 03-16-2013

I have a question for all of you! My 1998 pontiac grand prix gtp supercharged is starting and stalling after 3-4 seconds, however you can get it to run if you crank it 4-5 times. We put it on the machine, and got Codes p1629 and P1573. I am at a loss at what this could be because in Dec,2012 I had the aftermarket security/remote starter removed and a new remote starter put in, no security. This has been going on for about a year and a half, with the car starting and stalling 3 seconds later whenever it wants to. Any ideas? In January I also had the key tumbler replaced because it was broken. This is still happening.

the first code is security like you said, you can have that tuned out with a tuning program. you would need a local with a tuner to do that. or go to a dealer to fix it.

the 2 nd code i found this thread, Grand Prixs Of North America • View topic - P1573 could be more bad wires or the ecbm is bad. a abs scan would tell more where to look. that scan you need to go a shop to have done, and most will charge you to scan the car. but its better then just guessing and tossing money at it.
