I have a 91 Cadillac with a 5.7 tbi. Fuel pump occasionally comes on for 2 sec prime, but car will stall after 5 seconds. Other times there is no voltage at pump, either to prime, or when cranking. Seems simple, but here is the head scratcher.... Car still won't stay running even with FP directly connected to 12v source. It WILL run with carb cleaner sprayed in. Did both the FP and relay die at the same time? What other things do I need to consider? Done already... filter blown out - flows fine all fusible links to ecm (red wire fenderwell area) are good blew out IN line - not clogged while I understand that there are some other components capable of shutting off fuel (PUC and oil pressure switch) there are a non issue if power is directly connected to pump. sorry for the disjointed question cold beers in the fridge calling my name and I can't concentrate...

Best do a fuel pressure test. Should have chg. fuel filter from the get go. The only other filter is on the end of the fuel pump in tank. Bad gas and dirty gas will plug up fuel filter, hense burn pump up.

if you really have a carburetor as you say, you have a mechanical fuel pump so you will not have a fuel pump relay. if you have fuel injection then you do have a fuel pump relay, need to know which engine it is to help more.

need to have it scanned to see what codes it has but sounds like a security system problem factory or add on if key has chip in it security prob very likely.hope i helped

That eliminates the crankshaft and camshaft position sensors. Have you checked the fuel injector itself for an open winding or stuck valve plunger? There should not be a steady 12 volts to the injector--if good injector, it would be spraying fuel steadily into the throttle body. But at least the engine should try to run if poorly. Take the injector out, dry it off with air, and intermittently apply 12 volts to one terminal while grounding the other. You should hear a click from inside every time you touch 12 volts. If not, replace it. If it does, it may be plugged with debris. Try blowing through it in reverse with compressed air.

Been there before!!!! usually it turns out to be something really dumb that makes you say "Why didn't I look at that first???" (either while you are smacking yourself in the head , or, just after!!!!)
Good luck again!!!
