Bad Diesel?

[late4sho]

Hey guy's,

I filled up my tank last week, and my truck has run fine. The truck is at about half a tank full and has just sat at my girl friends place for about one and half days at a slight up hill slant. I just drove home and about an hour ago and my truck starting to shake when I would get on the gas and some times at Idle. I stop as soon as i saw a parking lot checked oil and Trans and all fluids and everything was fine...... Got back in truck fired it up still Shook and the “service engine light soon" came on and i am thinking F#@^
This is just great! So I limp it almost home thinking may be bad diesel i threw a $20 in the tank sat around for a sec..... And it ran fine all the way home.
The light is still on.... but was thinking that’s like a check engine light have to clear it?


What you think..... I am just hoping it starts up for work in the morning

maybe you have air in the system if it runs fine now unhook your batteries to clear the code if your fuel filter is old it could be a good thing to change it

hope this could help

Here's my How about draining the fuel water separator. It will run like that when you have water in the fuel/water separator. Its located top of engine center right behind the fuel filter. Yellow handle, turn sideways to open, drain until empty then close.Start and should run fine again.

Thanks guy's, i will give it a try

I got your message. Have you had any recurance or did draining the separator help?

[late4sho]

I opened the drain like you said for a couple of seconds, then closed it. The problem is still happening.

I am going to change my filter tomorrow, my only question is when i remove the filter i take out all the diesel out of the bowl and replace with new filter... Do i have to add fuel to the bowl, or when i turn on my truck to heat the glow plugs does diesel get sent into the bowl?

And this is my first fuel filter change, and advice you would give...
Thanks
