rockcrawler304 if you think my lift pump why is it a intermitten problem someone else told me they had a similar problem they replaced the throttle position sensor it seems like everytime i let off fuel and push in clutch it dies if you can feather the throttle it will stay running

 

FWIW, when my canister-mounted lift pump failed, it gave no warning. It just quit while I was making a left turn at a busy intersection. Fortunately, I was able to complete the turn and coast to a stop (lots of fun with no power to steering or brakes). I could start the engine after a bit of cranking but it would only run a few seconds and stall again.

 

njmurvin my truck has been doing this for a long time its never failed to start right back up i have codes p602 p483 p2509 know what they are but cant put them together

 

That's why I asked if you know what the lift pump pressure is.

It could be several things but lots of time it is fuel related. We would probably need more details of the problems you're having. And trust me, with all the knowledge on this site someone will pinpoint the problem! It just may take several questions and answers before we get there.

 

To the OP, you have 3 open threads for the same thing, so which one should responders use?
