I'm trying to figure out what the relays i see are?

88 5.8 drivers side under hood behind air cleaner box i see a brown, green, and a little further back gray relay. my problem is fuel related and i'm trying to track down these relays. thanks

 

Do you have the Haynes manual? I could email you the wiring diagram from my Haynes for your year. It may help. Email me at michaelwampler(No Email Addresses In Posts!) if you want it.
