Car Information:
Kia Sedona
Year: 2003
Engine Size: 3.5L
Trans: Automatic

Issue / Question:
Car starts fine when cold. Once warm if I go to start it, it cranks and then locks, key off, key on cranks and then locks or cranks without starting. Does a fast crank with a hint of starting but never does. Let cool and it becomes hit and miss but usually starts. Once started drives fine, no misses, acceleration good, idle good. Disconnected output on fuel pump and appears good fuel flow when cranking (Done when cold) Any ideas????

Answer:
The crank and lock scenario may mean the engine is hydro locking from fuel or coolant! (Not a good thing) if your not losing coolant it may be a bad fuel injector allowing fuel to enter a cylinder while the engine is turned off. When you go to restart, it has to chase the excessive fuel out of the exhaust valve before the engine cranks over normally.

Let us know if you want to get it in for us to check. Continued use may bend a connecting rod if condition isn’t resolved.
