Longer starts

[hondaracer315]

Hey guys, 02 7.3. My truck seems like it is taking to crank over it is a very strong crank so I know its not the plugs or the relay or the batteries. It'll do it in the summer too sometimes where it takes longer to start then other times like a couple seconds longer. What is causing this? Other times it will just crank right over no problems. Seems lately it is taking longer to crank over.

anybody have any ideas here

Over the last week temps in my area were around the single digits and the truck was taking awhile to crank over even with two new batteries. A buddy suggested that I pump the gas three times before attempting to start it.... Cranked over on the first attempt even in the freezing cold.

Now I am new to the diesel arena so I am not sure that this is the best approach... but it seems to work. Any reasons why this should not be done?

Yeah guys any other ideas I never heard of the triple pump

It could possibly be a leak in your hpo (high pressure oil) system that works your injectors you could pull the plug after it sets and see if the hpo reservior is full or down if not familiar with it a search here will yeild lots of info on it.

Mine is doing the same even with two new batteries and gpr.

"pumping the gas" does absolutely nothing on a PSD, if you aint crankin, you aint bulding HPO to fire the injectors.

to the OP, does it do it after sitting for extended periods of time? or is it just random?

as far as cold starting....let the glow plugs warm up for a while, not just by the wait to start light, do not cycle the key, pump the go pedal, etc. if your truck is not starting or starting slow in cold temps, there is a problem. usually GP or battery related, but can also be oil related, or old and tired injectors.

look here: Winter Operation, Hard Starting, Hissing Sound Etc...

Interesting, I dont doubt your explanation, but pumping the go pedal definitely had an effect on the way my truck fired. I suppose I will have to learn more on this topic...
