Im sorry you need to get a fuel pressure tester with a screw valve for GMs on the end. SEARS has some for like 40 bucks. its worth the investment :)Im sorry you need to get a fuel pressure tester with a screw valve for GMs on the end. SEARS has some for like 40 bucks. its worth the investment :)
how much pressure r you getting? the first thing is to see exactly how much pressure your getting, alot of the newer GM trucks need that 60psi to start. they can get 45 or even 50 and will not start. check that first. these are really picky nowadays
let me know,

the feul filter get a book and look were its located but it wouldnt be the ignition fuse it would be feul pump fuse when u turn the key in on position not starting the car youll hear the feul pump at the back of car kick on if u dont hear it replace the feul pump if it dose then its ur coils
Someone will need to check the circuit at the pump to see if it is getting power from the relay. If it is the pump should be running when you first turn the key on. You can also check for power at the pump relay.
how much feul pressure, it must maintain a certain amount if injected, or throtle body, try priming it ,and see if it helps, ( poor a little into inlet ) and check it , if it starts you need to check pump, or maybe just filter
It sounds like you have a security problem, I had the same thing it would fire and run for half of a second and then that was it if anything at all. Had the security system rebooted, now it starts and runs fine.
