Chevrolet Repair: car tries to start but wont run, fuel pressure gauge, camaro v6

Question
I'm trying to help one of my granddaughters school friends.The car is a 1999 camaro V6 3800 series II.They were driving down the road and it quit running.I winched it on to my trailer and brought it home.I got in the car here and it started right up.I let it run for a few minutes and tried to back it out of the garage and it died.I've tried to start it but it won't run.Any ideas fuel pump or fuel filter or computer problems.There are no check engine lights or warning lights on in the car.I'm an old big block guy and this new technology is a little over my head.Any help you could give would be most appreciated.Thanks ahead of time!

HI JAY, FIRST OFF WE HAVE TO FIND OUT IF IT IS FUEL OR IGNITION..IF IT WILL NOT START I WILL ASSUME YOU KNOW HOW TO CK FOR SPARK. SAME WAY AS OLD SCHOOL..SO LETS SAY THERE IS SPARK. NEXT FIND THE FUEL RAIL ON TO TOP THE INTAKE AREA,LOOK FOR A WHAT LOOKS LIKE A TIRE VALVE STEM CAP,IN THE FUEL LINE, [THIS IS THE PRESSURE PORT] REMOVE IT AND PRESS DOWN ON THE SHRADER VALVE WHEN SOMEONE IS CRANKING THE ENGINE OVER,IF IT HAS FUEL PRESSURE THERE IT SHOULD BE SPRAYING FUEL ALL THE WHILE THE ENGINE IS CRANKING OVER NOT JUST AT FIRST CRANK,THIS IS JUST RESIDUAL PRESSURE. WE WANT FUEL SPRAYING OUT OF THIS VALVE ALL THE WHILE THE ENG CRANKS. IF SO FUEL PUMP IS PROBABLY OK. WITHOUT A FUEL PRESSURE GAUGE THIS IS THE BEST IT GETS..OR YOU COULD REMOVE THE AIR CLEANER INLET AND SPRAY SOME STARTING FLUID DOWN THE INTAKE WHILE CRANKING. IF IT STARTS MORE THEN LIKELY THE FUEL PUMP IS BAD..IF NO FUEL, CK THE FUEL PUMP RELAY IN MAIN FUSE BOX IN ENG BAY AREA. REPLACE WITH ANOHTER RELAY NEXT TO IT TO CK TO BE SURE THAT RELAY IS OK.. IF THIS IS GOOD CK FOR POWER DOWN AT THE GAS TANK MAIN HARNESS PLUG, GOING INTO THE TANK AREA,PLUG WILL HAVE 3 TO 5 WIRES IN THE PLUG,CK FOR BATTERY 12 VOLTS POWER ON THE GREY WIRE WHILE ENG IS CRANKING IF POWER IS THERE AND NO FUEL,TIME TO DROP THE TANK AND GET A NEW GM PUMP..NOT AFTERMARKET..LOTS OF PROBLEMS WITH AFTERMARKET. THIS WILL KEEP YOU BUSY FOR A WHILE.GET BACK TO ME WHEN YOU FIND THE PROBLEM..THIS WILL GO TO MY CELL PHONE SO I CAN GET BACK FAST. PLEASE WHEN YOU ARE DONE WITH ME,, PLEASE RATE MY ANSWER. THANK YOU,,,TOM..
