truck not starting again

[hugeredford]

My truck has all eight new glow plugs and a manual controller and was starting very good just a couple seconds of cranking. Now the truck still starts right up and dies within 2 seconds then I have to crank for at least 1 minute to fire. I am getting fuel smoke at first then while i'm cranking nothing then it will just fire right up and only stumble a couple seconds then it runs all day no problem.Any ideas or should I put in the electric fuel pump. Also how are you wiring them in to the ignition.

Air, air, air, my friend. How are your return caps and lines looking? Try plugging it in overnight to ensure that your GP's are functioning right.

plugging in doesn't make any difference it's only been 15 derees for the past 3 days The return caps feel a little loose but i'm not shure if thats it but i'll get a kit for it. last week one of the braided overfuel lines was leaking right througt the hose fixed that thought it might help but it didn't seem to make a diiference. is there any chance it could be gelled or fuel filter it only has 3500 miles

Sounds like air, allright.You fire right up, untill the air get's into the Injector Lines. Then she dies. Then you crank untill the air is passed thru the injs.

Sounds like the return caps got knocked loose when doing the GP's Get the air leak stopped. and you will be happy.

If your return line seals check out, there are two seals in the inj pump supply line, one on each end. This can cause a problem with prime and may not leak much fuel (trust me). If you have a metal return line from the pump, there's another one of these seals but I think larger.

does anyone have the part #s for the hardline seals you're talking about? i just got a set of new injectors and return line kit and was thinking i should replace the seals also
thanks

pkg of two for supply line. I haven't got one for the return line, I have an electric pump and since it doesn't leak fuel (and is easy to get to!) am not worried about it. Could probably take your line to a seal place and pick them up cheaper.

thanks, i am just trying to cover all my bases till i get this air leak figured out

 

[hugeredford]

I just put new caps hoses and orings on I'll see how it starts in the morning

 

[hugeredford]

Well so far I have put on a fuel pump, filter, and all of the returns and orings and it's not any better any suggestions or ideas

You should go and rip it up the highway for about 15 minutes to ensure the fuel system has been purged of air after installing any new components. That will give you a more accurate assesment of your repair in the morning...

If you still have trouble in the morning it could just be residiual air in the system, and not a current leak, if that makes sense...

Actually that won't get all the air out. If find that what is usually needed is 3 driving "cycles" to get all the air out. Each time you shut it off, the air moves to places that it won't move while it's running, and then it will purge when you restart, but it seldom gets it all out with just one repitition.
