well when the ol john deer went down I had the fuel pump rebuilt and after I put it back on it would do something similar . it was a clogged return line for the fuel . do these new fangled deisle trucks have return lines on them . some of the spider gear off of the pump had passed into the lines and after I cleaned it out all was well .
yes these new fangled diesels hav return lines, but he has a 1500 aka: 1/2tn with the 5.6L 360cid gas burner.
Justin, the O2 sensor was insence shorted out on mrs Diana's tck, it was telling the onboard computer it had to much fuel and to shut the fuel supply off, or to much O2 and it flooded the eng out. a clogged cat will cause a similar issue by not blowing out what the eng sucked in. its kinda like some folkls with cabbage or beans, we intake the fuel, but and blow out the tail pipe, but if we were clogged up, we wouldn't b able to take in much more fuel until the we got unclogged. thank goodness for exlax
