Are you allowing the the intake air to heat up befor you start?

Any time you start your pickup you need to let the "WAIT TO START" light go off then crank it. If you are doing this and still having trouble your grid heater could be shot. If that's not the problem make sure you check all your fuel lines for wet spots indicating a leak. Try plugging it in at night or put it on a timer for a few hours before you plan on starting it.

Ok, your geting fuel. you might be burning some oil. How many miles? and have you disconected the Quadzila to see if it runs normal? Some thing easy to do When you first start it, get a Lazer temp gun and have some body start your truck. Point the temp gun at the exhaust manifold and see if you have a(ny) cylinder(s) that are cold. The one(s) that are slow to warm up you might want to do a compresson check.

check the return banjo fitting at back of cylinder head,just a slight wetness around fitting will cause bleed down in fuel rifle and cause hard start after sitting over night.
