HEllo everyone, I have a question on my 98 dodge avenger 2.5 v6 there are 3 boxes under the hood on the firewall on the drivers side.. What are these, I cant find the information on them.. Are they fuses or relays and what are they for,, I unplugged all 3 of them and there is a bunch of goopy looking white stuff around all the connectors in them.. My car has been dieing when i put it in gear and give it gas so wondering what these are and if they have anything to do with that.. thanks

 

Those are three relays There is a sticky explaining them
Fuel pump relay / ASD relay can cause the stalling cutting out
