Supra5994

The motor does start and the starter is working fine it start idles just above 1 grand and then dies two seconds later I have gone through and checked every connection I could find to look for loose or damaged wires it stays started when I spray start ya ***** in so I thought it may be fuel pump but I check the injectors and fuel is getting pumped so I have no clue when it does start it sounds normal but as soon as I give it throttle it pops and moans and dies

My car keeps downgrade as soon as it starts I have tryed everything I can think of really need help please
