ok i have a 98 g1500 350 5.7 vortex... transmission went out about 2 years ago just now got around to putting a transmission in it got it all hooked up and it wont start it cranks it has spark and fuel... i took the injectors out cleaned and tested them new fuel filter checked pressure of fuel pump was good check timing did the plug, wires, distributor cap, rotor bottom added about 8 gallons of gas to it but didnt drain the tank runs for about 5 seconds before stalling... security light is on but it doesnt flash like it was locked out... any suggestion would be great full

Ok im new to these motors do we have throttle bodies were there is only two injectors that sit on top or what?

madville16

well i though it was dual port but after getting it apart there is no injectors inside the throttle body just the injector to each cylinder.. but let me ask you something did yours sit for awhile and was the transmission replaced?
