tbi injector issue

little help for my gmc truck please. i got a 95 3/4 ton with a 350 tbi. i can't get it started been sitting for a couple of months, just got back from deployment. i have good fuel pressure and it's up to the tbi but it won't come out of the injectors. not sure if there is a relay that powers them after the ecm or not. or should i look at something besides the relay. all fuses are good. any help would be much appreciated. thanks. lit2crz25

It could be a dead or dying fuel pump. Do you hear the fuel pump prime when the car ignition is on before you crank it?
