Bought the truck in August off a car lot. 208k miles, crew cab 4wd. It fired up easy, pretty quick, ran good. The exhaust manifolds were not warm to touch, probably run earlier in the day. When October came, the truck was slow to start, runs rough for about 10 minutes, then runs great. Now that it's as cold as a witches tit in a brass bra, the turd won't start for an hour. It seems like the injectors are loosing prime as it sits. Any advice is welcome.
I put a 4.1kw starter on it, it spins like crazy now. It's a DB off amazon.
2 good batteries, the glow plugs pull the volts down to 11.9 before I crank it.
Did an injector buzz test, nothing an untrained ear can discern.
Fuel pump is pushing fuel, new fuel filter in the engine valley. Didn't check psi.
Fresh oil right after I bought it, I was hoping fresh oil would clean up the slow start, rough running. No such luck. Oil is 15w40 Harvest King, black as coal after 20 minutes. I regret not sucking the injector oil sump out.
What are the chances a stiction oil would help this?
Any advice is welcome.
