Dodge Ram 1500 Intermittent Warm Start Issue
2005 Dodge Ram 1500, 5.7L; I’ve been
experiencing intermittent warm start issues. After
letting the vehicle sit for 15-30 minutes, it will crank
without any combustion. The only way to get it to
start is to open the throttle 50%. The vehicle starts
just fine when it’s cold. This warm restart issue only
occurs after reaching full operating temperature
and letting the vehicle sit. The vehicle restarts just
fine right after turning it off.
I’ve tried fuel cleaner additive, different grades of
fuel and smoke tested for vacuum leaks.
Any ideas?
