GMC SONOMA CHECK ENGINE LIGHT PROBLEM

1994 GMC Sonoma • 18,200 miles

Hey! Have a 1994 Sonoma that ran but surged all the time and when I wanted to accelerate it wouldnt go like it should. One day I was low on fuel an it died on me so I beat on the fuel tank an it fired up. So I thought it was a fuel pump. Put a new sending unit an all in it wouldnt start. Put the old everything back in an it fired right up. Took new sending unit back thought I had a deffect. Got the same thing still wont start pump does kick on. So I decided to put old one back on wont even start. Spray ether in intake fires up til it burns that off please help?

Do you have a check engine light? Check the fuel pressure if its within specs and also if the injectors are pulsing-start here and then let me know-
