I'd sure wire up a battery +volts set up to the pump itself with a switch before I sold the thing.
I didn't test resistance, but I had 12VDC (12.something but don't recall exact) when I tested during pump replacement. Assume it would be a good 13.8VDC during operations. I am well aware that does not measure current and subsequent heat-induced problems with a load sink.
My 07 rocks always starts up immediately and fuel no longer boils. Sorry you didn't follow my tips.
If your tank doesn't leak then the pressure increases with heat = impossible to boil.
Everyone who has boiling fuel has a leaking gas tank, fact.
If I "vent" the tank from the cap, yes there is positive pressure in the tank. FWIW, I've never had fuel boil out at me like I've had in other vehicles. I'm not sure what tips I have not followed (if that was directed at me?)
Have you done a cooling system overhaul? Do you hear exhaust more than you should in the wheel wells?
Yes, I replaced radiator sometime ago (late 2018 IIRC), and a distilled flush with refill September 2020. No signs of sediment, fluid loss, etc. To be fair our >560 mile dirt tour last October I had zero (re)start issues.
Maybe I missed a few posts about the exhaust sound??
