I was driving yesterday, took a turn into the mall for some last minute christmas shopping, and suddently the car just dies. Setup is a internally stock LS with a drag 3 kit. Basically the motor died and when you start it up it starts for like half a second then dies, and if you give it gas while starting it it'll stay on but sputters and then it's like it is hitting rev limiter at 2000 rpms. It's blowing a shitload of smoke. Also it seems like the motor is putting out a ton of exhaust now because it was hitting like 2lbs of boost at 1500 RPMs (keep in mind this is a t3/t4 60 trim). So it's getting air, fuel, so i was thinking ignition?? i have no idea, how the hell does it just die like this out of nowhere!?


I can't figure this out and i need to drive my car!!


help?

 

is it getting fire?

 

Check your coolant and your oil...look for anything unusual. Should also check you plugs. What color is the smoke?

 

it was running all weird and blowing smoke everywhere cause i found out the diaphram in my AEM FPR had gone bad, plus it wasn't holding fuel pressure. so all that smoke before was unburned fuel. the AEM FPR was replaced with an ITR FPR as a temporary solution. Now it holds fuel pressure, but now it won't start

 

change the plugs to some new ones

 

check the fluids it could be a head gasket, this happened to me with my turbo gsr
