Starting Issues...

Hey Guys! I have a 2006 Pontiac Grand Prix with 51,000 miles. It has the 3.8L engine. (non-supercharged)
Okay, so now I have a new problem and I'm not sure what's going on...when this first started happening, I didn't think it was a big deal, because it only happened about once every week. Now it happens about every other day.
When I go to start the car (cold start), sometimes the car will start and then sputter and die. I wait about 10 seconds, and then turn the key over again. The starter stays engaged for about 3 seconds while the engine is cranking (even though I let go of the key it continues trying to start) and then it will finally start. It does the same thing when I used the remote start. When I start the car after I have been driving it, it works fine.
Should I check the fuel pressure? If so, what should it be? Is this something I am going to have to worry about? Will it get worse?

It sounds like a malfunctioning remote start. Is this a factory remote start, or an aftermarket/dealer add-on unit?

This is the factory remote start. I have to mention that it does this when I start it regularly (without remote start) and when I started it with the remote.

It sounds like the PK3 system is bad or your BCM is faulty. Have you ever seen the security light on?

No, I have never seen the security light on. It started happening more frequently after the dealer did a reprogramming for a recall. All I know that they did was recalibrate the SDM (sensing and diagnostic module). It dealt with the seatbelt reminder and the remote start feature. Could this have messed it up?

Yeah I'd take it back. They could have accidently messed with some sort of parameter they shouldn't have.

I had a similar problem on my 04 model and have encountered it on quite a number of GM drive by wire throttle body vehicles coming into the shop. A good cleaning of the throttle body cured my problem (and the others as well). This seems to be the cause of many cold/hot start and stall issues on the 04 and up models.
