Your best bet , take it to a qualified repair shop . You have know idea how complex the electronics are on your vehicle are . So before you short something out an make thing's worse . If it shuts off after 4 seconds it's a anti-theft problem . Take an have full vehicle scan done , Knowing how the start system works is the way to a fix . Turning the key to start send a voltage input to the BCM ,the BCM sends a message over the GMLAN serial data network to the PCM / ECM - engine computer requesting start , the PCM / ECM will then energize the starter relay sending battery voltage to the S terminal on the starter solenoid . The PCM / ECM isn't receiving a message from the BCM telling it to enable the fuel injectors . anti-theft system code ok

Take + terminal off the battery and leave it sit for 2-3 mins. This act's like a reset-to default factory settings...I had same problem on my 97 Z28, endeded up being the negative terminal to the battery was just slighly loose. I noticed it while disconnecting the the battery to reset my ob-cpu...Try this and let me know if it worked... i should!

I was having the same exact problem with my 2005 neon as well. The guy at Discount auto suggested the starter itself was the problem(cost approx $200). The car isn't old enough to be having a starter issue so I figured it was something more simplilar. My dad took a look and founf out it was the starter relay. It is located in the black fuse/relay box on the driver's side right next to the battery. I had to get a new relay at the dealership(cost $20) and my car starts perfectly. Hope this helps

The security system (VATS/PassKey) is faulty. You can find a great write-up here: http://newrockies.ca , it was the only thing that saved my Park Avenue.

sounds like you have a starter solenoid problem. Or maybe loose connections on solenoid.

What's this , light rollover ? The vehicle was in a roll over accident ? Air bags go off ?
