2003 Ford Ranger - Something got wet, but what? Help Please

i had bought truck from someone who lived on graveled road. had 4 years decided to degrease engine.Now it starts every time but doesn’t want to run and sometimes dies. iam sure got something wet that shouldnt of

Who knows! I hope you didn’t use a pressure washer to clean the engine because thats the worst thing you can do.Water gets everywhere… electric parts,fuse box etc, even if covered with plastic bags.

It starts OK but doesn’t keep running? Maybe the oil pressure sender is wet and that keeps the fuel pump from running.

Check the air filter box. It may be full of water.
