Default Heavy on fuel and backfiring

Hello everyone, i recently bought a 1995 chevy Blazer, and i have been having some troubles with it. First off, it backfires and sets off an engine code. Seccondly, its VERY heavy on fuel; probablly 100km/full tank. The blazer has a 4.3 L vortex, if that helps. If i disconnect the battery to clear the codes, it runs good for about 5 minutes, then service engine light returns. Any advice would be appriciated. Thanks in advance.

Well first off I would go to a shop and just have the code read so you at least know whats going on. Wouldnt you want to know what the code means so you can fix this problem, clearning the code will not help...it will just prolong this problem.?

Yup, get the code read for sure.
It sounds like an internal fuel leak from the fuel pressure regulator or an injector.
