I just installed a new 5.0 vortec and it will fire up for about 1 sec and then it will die. I am getting fuel but won' keep running.any ideas would be helpful.

is your security light coming on? you might need to reprogram your security to the key. it will allow a start up but then turn off your injector pulse killing the engine

put the key in the ignition and turn to start for just a split second and then leave the key in run with the engine not running for 10 minutes. then turn the key off for 10 seconds. Sometimes it may take more than one time but usually one time will reset the module.
