I have been working on this truck for 1 year now. It was a flood truck and the whole thing has been rewired and flashed at the dealer. It still won't start. I took the injectors out, had them tested. Meanwhile, I put ATF in the cylinders, because I had no compression on the no.2 cylinder. The rings were siezed, but now I have compression. I put it all back together and bled the lines. It almost cranked, but not quite. I cranked and cranked on it and now it doesn't even want to start. I imagine it's flooded. I'm disconnected the fuel pump to solve that, but now I have to recharge the batteries. When I crack the lines going to the injectors, the diesel drips out. My question is...shouldn't the fuel pressure be really high? My son was cranking while I bled the lines, but I expected the fuel to shoot out, not just drip like an old tractor with a mechanical pump. I thought these 6.7l were supposed to have 3000 psi- enough to cut your skin.

 

You don't need to bleed lines on a cr.
When you turn key, you can hear lift pump.
Was your lift pump under water.
some guys spray wd 40 in intake to see if
they can get them to fire.

 

The batteries are fully charged and it barely turns over. I think it's flooded. I sprayed wd 40, carburetor cleaner, and ether.

 

Even if it were flooded it should turn over
with good batt. Was this motor taken apart
to check for rust on walls and rings. Did
you have ecm checked.

 

ECM was checked. The head was never pulled to look at the walls or rings

 

I would pull the Injectors and look with a borescope.........Either that or your starter is dying.

 

Yep, the starter is definitely dying. I think I'm going to take it to Texas diesel injection in San Antonio before I just set it on fire
