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
Justin, you are kinda right on what happen to our (djhogdogger) truck. The truck we have is 94 dodge 1500 with 5.9 gas engine. It was doing the same thing that Big Chris truck is doing. Then one day it just stopped running. I spent a few bill's on changing out sensor's and come to find out it was the Cat Converter. It was plugged up. So I rodded it out for now. There wasn't anything wrong with the O2 sensor. You can check the code's but its a pain because you have to count how many times the mileage flashes (There is no plug to plug a scanner into on this model). I did this and come to find out, it wan't any of the code's that was coming up.
Big Chris, Do this only when the truck Will Not Start After it has been running. This is how I was told to check the the Cat Converter. (1st) Take the O2 sensor infront of the Cat Coverter out (O2 sensor between the engine and Cat) and let it hang there.
(2nd) Then start the truck up and run it down the road a little way's and see how it run's. It will be a little loud with the O2 sensor out.
If it doesn't die on you, most likely the Cat is plugged. If it die's on you, it has to be a sensor going out on the truck. Thats when you will have to count the flashes on you mileage.
Good Luck
