fuel problem

I have a 94 cutlass cruiser with 79000 miles on it and it won't start.It acts like a fuel problem when i put a gauge on it shows 0 with key on but when i put 12v to the fuel test lead i get 47lbs and i change the relay and check the fuse all good gave it a little shot of starting fluid and it started and i tryed to start it with the fuel test lead connected but it still won't run and help would be great thanks.:crying:

It tests good at the fuel test lead but will not run with 47 psi? Do you have injector pulse? BTW, what engine?

It tests good at the fuel test lead but will not run with 47 psi? Do you have injector pulse? BTW, what engine?i do not know if i have injector pulse how do you check that it has no preasure with the key on or if i crank it only if i use the fuel test lead is there something eles i could check and the motor is a 3.1 thanks
