alright guys its done this like once or twice a long time ago but hasnt done it till friday when it started doing it constantly my truck whenever its cold even after running that day and sitting for an hour starts like crap it turns over way more than it should or normally does, but it does start just turns over more. once it is running tho it runs fine and if i go to start it with it being warm it starts perfectly fine but if i let it sit and cool down it will start again bad dont kno if its my fass pump or what ? if u got any ideas tell me thnks

 

Sounds like you have a fuel leak...check where the fuel line meets the connector tube in the head. Alot of times its just bad o-rings that need to be replaced.

 

thanks man i just tightened them up and she started right up

 

Ok shes stil starting like crap when cold a day later even after makin sure all the connectoer tubes to fuel lines were tight any ideas wat else

 

Check your air bleeder valve at the fuel filter housing for a leak. Sometimes the o-rings inside start to leak and you lose a bit of fuel from the filter while it sits. Happened to mine. I doubt it's cold enough where you are for air heaters not working to cause it. It would have to be pretty cold if it's not starting well after sitting for only 1 hour. Hope you find something.

 

Have you ever replaced your fuel lines? If not, they could well be in need of replacement.

When you start your truck, if you give it fuel right away, does it stumble or does it take right off? If it stumbles, it could well be air in the fuel system.

One way to check this is to install a short section of clear fuel line and watch it as you start up.

 

it looks like my fuel return line either has a crack or the fitting is leaking after climbing around in the dark with a flashlight haha

 

Check your overflow valve then too. The OFV should keep the fuel in the VP when its not running. Mine wasn't doing that and caused really poor starts.

 

ya the truck is stumbling when i go to start it and there is fuel on the right side of my block back near the 6th cylinder

 

There is a banjo bolt on the back of the head for the return line from the injectors. Make sure thats not leaking either.
