1995 Chevy Tahoe Lt 2 door 4x4 has a vortec 350 v8 and wont start

Since it will run on the starting fluid it's a fuel problem. Sitting for that long I'd drop the gas tank, clean it, and replace the fuel pump assembly. If you find varnish and/or water in the gas tank I'd also replace the fuel injectors and blow out the fuel lines with compressed air. Replace the inline fuel filter too. My 2000 Grand Prix was my Nephew's first car and we were very close. So I understand sentimental value!! Best of luck to you with your project!! Hope that helps! Jim

I replaced the gas tank, fuel filter, and fuel pump, they are all brand new. got them about couple weeks ago, i forgot to mention that but, im going to try to clean the throttle body see it that does and if it doesnt do it, ill clean the injectors. keep in mind that fuel line is new to and im getting around 60-70 psi in the line. i hope its just clogged injectors
