Yesterday I was working on my 02 lb7 and accidentally left the key on when I was done, and the key stayed in the on position for about half the day. Truck started without issue and ran fine afterwards. This morning I went to get in my truck and noticed a huge puddle under my truck that seemed dark like engine oil but had mostly dried up and was residue. I planned on doing an oil change soon anyway so started to drain the oil and drained approximately 4+ gallons out of it and it should’ve only had 2.5 gallons max. After the oil change I haven’t noticed any more leaks or drips at all. Not sure if the key being on could’ve caused fuel to pump somewhere it should not have the entire time? Or do I have a bad injector and it has been putting fuel in the motor and With time it finally had too much in it and caused the leak? Just seemed like weird timing to have the leak and large puddle the morning after I left my key on for an extended time. Hoping injectors are not going bad. Any help with this issue would be appreciated.
