car not starting unless plug is removed
Asked by dimebagbubba May 06, 2016 at 02:27 AM about the 2002 Ford Explorer XLT 4WD
Question type: Maintenance & Repair
2002 ford explorer 4.6 won't start unless a
spark plug is removed. Coolant busted out
up from behind engine. Started running
terrible now it won't run unless a spark plug
is removed. Why will it only run while a plug
is removed?

Blown head gasket, the cylinder is filling up with coolant causing a hydrolock. Coolant is liquid and non-compressable. I'll bet it is losing coolant also.

And it will run when I remove the egr valve. As long as there's somewhere else for air to go, it'll run. No more than 2k rpm though.

Nothing wrong with the oil. Wouldn't it be milky looking or something in it?
