I was on my way to work driving down the freeway when my engine just died. It will start and run for about 3 seconds before dying again. It starts every time and dies every time. I tried giving it gas as its dying and it didnt even bog or miss or anything. It's almost like the computer is either turing off the ignition or the fuelor both. The only way to keep it running is to hold the gas down and bounce it off the rev limiter. I also tried holding the rpms at about 2000 rpms and when I feel it about to die I quickly turn the key off and back on again and it continues to run another 3 seconds until I turn the key off/ on again.
I disconnected my maf to see if it would run and that did not help, same deal. I also swapped the two fuel pump relays, no luck. I scanned with my hptuners and see no codes or any sensor information out the ordinary. I tried running the fuel pump in high speed and that didnt help. All I can say is that I just fueled up about 20 miles before then and changed my trans fluid the day before. Also I'm not running any o2's.
I'm completely stumped!!!!
