3.4 swap runs for 2 secs then dies
Just swapped a 3.4 into my truck and i can get her started and running but then the engine will run for about 2 seconds then die. I plugged all the vacuum lines. Im possibly thinking it might be the fuel filter??? i just replaced the fuel pump for the 7th injector and supercharger.

It almost sounds like it's struggling to idle for those 2 seconds. Are you throwing any codes for cam or crank position sensor?
Maybe check that the fuel pressure is good (you could have installed a "bad" pump without knowing it).
Did you add on the piggy-back controller for 7th injector? Did the motor run before you added that controller (URD or TRD)?

Yea i figured it out a couple of days ago. I unplugged the 7th injector ECU and she started right up with no problems and was running. So i need to figure out what i was not correct with the 7th injector.....
Here is the video of the motor running
