OK, guys...give me some ideas here. I'm pretty new to diesels (just bought the truck a few weeks ago), I've noticed that lately after the truck is good and warm, that the truck cranks longer before it fires up. Example, on my way home from work today I stopped to get fuel. When I hopped back in the truck to take off, the engine cranked over for a couple seconds before she fired up. Yes, I waited for the "wait to start" to go off. (The amb. temp was near 90 degrees also.) The engine cranks and starts great when the motor is cold. Any ideas what could be causing this? The truck has 44,000 miles on it and has had dino oil in it since new...recently changed too. Fuel filter is new also.

HPOP leaking down? Oil getting thin in hotter temps? Glow pug relay?

Thanks in adavnce! /ubbthreads/images/graemlins/biggrin.gif

Probably not, but easy to check

Newdieselitis - Probably.
If it's only a couple seconds, don't stress over it. We've all been there. /ubbthreads/images/graemlins/phoney.gif /ubbthreads/images/graemlins/grin.gif

mine starts better when it is warm if you don't wait on the wts light to go out /ubbthreads/images/graemlins/shrug.gif

Are you just jumping in and starting it, or waiting for the light.
I wait for the light to come on, but very briefly, I don't wait for it to go off if the truck's already warm.

Nope, I'm waiting for the "wait to start" light to go off before I try to start it. Are you guys saying that if the truck is already warm, don't bother waiting for the "wts" light? /ubbthreads/images/graemlins/shrug.gif

Try that, wait for it to come on, but not go off.

I turn key on..... 1 - 2.... start

The truck in my sig now as 53,000 miles. It did the 'crank longer when warm' thing often before. I haven't noticed it much lately. I bought the truck two years ago with about 38,000 on it. I don't know what oil the last owner used. I use Rotella 10-30 in the winter and 15-40 in the summer. This oil makes it start perfect in those temps. I usually wait for the WTS light on a cold start, but the truck will start easily if the outside temp is above 50 degrees even on a cold start. If the truck is warm in the summer time there is definately no need to wait. I used to be careful with the waiting when I first got my truck also... you'll loosen up over time /ubbthreads/images/graemlins/biggrin.gif
