2006 Chevy 6.6L Duramax

For the past week my truck has been hard to start when cold. It is fine when hot or and under all driving conditions. It is worse the longer it sits. Robbie heard what it does in Alto after sitting for two days. It cranks for about 10-12 seconds before firing up. I thought it was an electrical problem because the voltage is low (10-11volts) on initial start up but quickly rises to 14 volts after a minute or two.

I popped the hood and instantly smelled diesel fuel. The fuel filter is leaking and it is obvious. It is not leaking at the fuel filter fitting or the water in fuel sensor but instead is leaking at the small push in connector on top of the aluminum fuel filter housing with a red wire. I assume this is some sort of sensor? If I prime the pump by hand I can hear and see small bubbles rise up at the base of this sensor. What is this sensor and how do I fix this? I change the fuel filter religiously with WIX filters and did the last change about 2K miles ago.

Thanks.

It is leaking from the plug in sensor with the red wire. Seen here:

Have you tried to search dieselplace yet? I've never heard of it leaking there before. I don't doubt you're going to be replacing the housing to 'fix' this. Let me know how that goes. Mine is a biatch to get to and want to relocate it or put in a set of inline cat filters one day.

I watched this and ordered a $20 o-ring kit that will be here on Wed.

I will let you know how it goes.

Looks like wiring for the fuel heater.

In that thread they are saying you can replace an o ring to stop the leaking. Yes I know that's not the same engine you have but the ebay link to the filter housing says it's the same housing.

During my last swing in Australia mine would loose prime and when ever my dad or brother needed to borrow my truck they would have to re-prime the fuel system if it sat too long. Turns out the fuel filter was leaking air into the system, my brother changed that out and no problems since

The $20 oring kit will fix it right up. Mine was doing the same thing (for the last year) and I replaced the o-rings and I haven't had any problem. It is a really easy job and took me about 30 mins, maybe less.

A cummins would never do that.

FYI, that is not a sensor it is for the fuel heater

I'm broke down with my dodge waiting on a wrecker right now.

Also my fuel sending unit is out so it might be out of fuel also.

Well the pos250 will be upgraded to a dually and flatbed after losing a tread doing 80. It's a bad picture but the inner fender, wheel well and bedside are trashed.
