My Rav still hesitates to start when it's been sitting overnight. Not the battery, not the starter. I'm going on the theory the fuel line is losing its prime overnight. I don't hear any fuel pump sounds when I turn the key on but don't start so I suspect the EFI relay might be on the fritz.
From what I read, the EFI relay sends power to the fuel pump at start up. After that, what I read said the fuel pump gets its electricity from another circuit and the EFI relay doesn't do anything. Does that sound right to you?
Looking up the replacement EFI relay, I've seen RY302 and 20382. Picked up a 20382 at Autozone. The box it came in say 20382 but the relay itself has a bunch of other numbers on it. All the relays look alike, are they different inside? I mean besides big amp side open with the small closed or big amp side closed with the small side closed. What do all the numbers mean?
