So today i put in a new gas tank on my 83 bronco. It started fine with a gallon or 2 of gas in it, then about 2 minutes later it stopped running. And wouldnt restart. When i turn the key to the on position i cant hear the fuel pump buzzing or an ything. Does this mean i have to press the fuel relay? and where is that at? what else could keep it from starting? it cranks...but doesnt get going. thanks for any advice. i really need my truck to run!!!

I think on your 83 Bronco, there is no electric fuel pump or relays and no buzzing sound, that's only on EFI or fuel-injected motors. The fuel pump is mechanical, meaning that the turning of the engine draws fuel from the tank. It is a major task to replace the tank, so give yourself a pat on the back for doing that. Just check to be sure you connected the lines right, and that you are getting fuel to the pump on the side of the motor. If you have gas at the pump but not at the carb, then the pump is bad.

I know you said you have about 2 gallons of fuel in the tank but try putting another three or four gallons in then try it again. The fuel pickup sits about an inch or two off the bottom of the tank so it might not be getting the fuel.
If you have plenty of fuel in the tank then check for fuel at the pump like justshootme84 says. Also did you replace the filter?

ok, i wasnt sure that it had an electrci fuel pump or not. No i didnt replace the filter. I will add some more gas today, then try it out. How do i check for fuel at the pump? and do you mean the pump ounted on the frame rail? or the one in the tank. Its gonna be difficult b/c i dont have accsess to a lift of any sort until next week (im on spring break, and the broncos at school!) thanks for your replys.

83B, your fuel pump is located on the engine, just trace the fuel line from the carburetor back to it.
If you are going to do work like this on the Bronco, it is a very good idea to buy a repair manual. "Haynes Repair Manual for Ford Pick-ups & Bronco 1980-1996" is the one you want, and it's only about $15 at any auto parts store like NAPA, Pep Boys, AUtoZone, etc. If you can't find a Haynes manual, there is a lso one from Chilton.
These manuals will explain in detail and with pictures how to chekc things like the fuel pump, troubleshoot most problems, and offer general info on your specific year model Bronco. I learn from it everytime I open mine up!!!

I replaced the fuel filter and blew compressed air through the fuel lines with no luck. 
it sucks to have nothing to drive i just figure we got something hooked up wrong above the tank. i just have to wait till school starts again to check that out. i swear this ha s happened to me about every couple months. so i just hope that nothing is seriously wrong! 
also... if a vehicle is sagging in the rear end does that mean you have to replace the leaf springs? and is that a very difficult job?? thanks for any info!

No its not hard all you have to do is pritty much take off the Ubolts that go around the axle, then unbolt your leafs. You might also want to watch that you don't snag your brake lines.
