HELP - CRANK, NO START :(

I don't know whats going on...

I've been having fuel head issues, and seemingly low battery voltage...although that is not a problem today..spins nicely...

I popped the hood first thing this morning before trying to start.

Passenger side battery was 12.53, Drivers side was 12.85

Fuel Bulb needed priming.

Truck started right up, let it warm up a couple minutes..stuck it in reverse rolled back 2ft and died.

Now I have complete NO START condition, cranks and doesn't fire.

My TECHII - can't read its sim card to initialize.

WTF? #LIVINGTHEDREAM

Sheesh...where do I start and please realize I'm not working and have little money to spend so need creative options!

HELP!

It sounds like an oring gave up the ghost and now the head is just sucking air
I would start by rebuilding the head.

Do you have enough fuel line there to trim off the bad spot and give you some solid line ?

I'm confused the Doorman kit has 2 gaskets and 3 o-rings
The Standard has 2 gaskets and 4 o-rings


Which one do you buy?

Phew.. I'm not sure, it's pretty tight in there I'll have to get a better look... I'm certain there's nothing leaking OUT of it...but might be sucking eh?

Is that the inlet from the fuel tank side that shows the cracking?

There is potential for air intrusion there.
If you can wing it just cut the line at the bad spot and then reinstall.
Be sure that there are no kinks in the line after you are done.

If it's too short then I would get a couple of feet of fuel line at the auto parts store and replace it.

The standard includes an oring for the bleeder screw
whereas the dorman kit excludes the oring..

OKDually - thanks for all the help!


I called around locally to try and find a head rebuild kit - none in stock, and wanted 40.00 anyway!


I'm ordering the Standard kit from rockauto right now.


Am heading out to take another look at a field repair on that hose.


Could that crack in that hose alone be a "no start" condition if it was leaking?

Yes, if that line is cracked just enough to allow air to get sucked in you will have a no start condition.
Since the Duramax is basically a gravity feed system, any air would block the fuel flow
