Kinda odd that it wouldn't fire up even briefly with starter fluid.Fresh gas and starter fluid didn't do the trick. I figured I might as well knock out another "maybe" and replace the battery, it was 2 years old and had been sitting dead for months. Luckily it was still under warranty and only ended up costing me $12.
Still no start though. Maybe I flooded it trying to start it so much on a low battery. When I first tried starting it after the new pump in there was a strong "bad gas" smell around the outside of the truck and occasional popping/firing. Now it's nothing.
Does cranking it with the pedal on the floor work for these trucks? I know for some cars it cuts the fuel so you can clear a flood.
I've been with the stale gasoline thing and after the first attempt of a decent amount of cranking without even offering (now the weather here has turned cold) a squirt of lighter gas (butane) into the throttle body and it fired right up and kept running next turn of the key.
My fuel BTW was almost three years old.
