My truck doesn't want to start. I undid the fuel line into the carburetor and cranked the engine. It'll spit out the gas. But when the line is hooked up, gas isn't coming out of the jets. I unhooked the line again and had it spit some gas into the carburetor. It fired up again(after reattaching the fuel line) but didn't want to stay started. No gas. OK, bad carb. It's still under warranty so I returned it. The new carburetor ran for 1/2 day. Then same thing. Got a new carburetor, hooked it up and it ran fine last night. This morning nothing... won't work. What is wrong? I put the high test gas in there, always have. Why is she mad at me. I changed her oil and fluids, of all types. Giving her a face lift and all sorts of cosmetic surgery. What else could she want? Is it possible the fuel pump is still bad? I unhooked the fuel line and pump gas into a clear container and the gas looked real clean. No junk floating around in it to clog up the jets or anything. I really need some help here. 350 motor by the way. I just can't believe all these carburetors are bad.
