[ncdmax03]

My 03 has been gettin hard to start it's got 2 glow plugs broke
Off and the other ones hooked up. 2 new red top batteries and new starter. Sometimes it will fire off after bout 15 sec then other times it won't fire off at all. What could I do ?

Did the hard starts begin when the temp starting dropping outside? How cold is it where you're at?

it did it back in the summer and I changer batteries and starter and it quit now its got worse and it wont fire off at all its been 70 to 20 and it don't matter when it is after it runs a while it still takes a while to crank could it be the relief valve?

You have to see if you are losing prime . Next time it doesn't start pump up the primer see if that helps it start. Also when is the last time you changed the fuel filter?

If it isn't a prime issue then you'll have to start looking into possible injectors. How many miles on the truck?

 

[ncdmax03]

The truck has a lift pump and maybe 30 mile on new filters

 

[ncdmax03]

truck has 93k on it

the injector balance rates look good the worst one is at 2 could it be a fuel return issue

I really need help anyone never head or heard of this issue

sounds like the injectors are returning to much fuel back to the tank. I had mine do the same thing. Started out to take a few seconds longer to start. then it got to the point if you got it started you better not turn it off. because it would take forever to start back up after it had been running for awhile.
