where is fuel injector module on 1994 deville 4.9?

leaking injector----check your fuel pressure regulator...it's diaphragm and it's vacuum action on that diaphragm...check for leaks and normal operation~

maybe these will help...Cadillac DeVille, click to get full screen...lower right second from bottom..but listen to Judge Roy, it may not be relay

Well after looking it's just a fuse, but I will leave it up

juicin' the goose...that's all I'm sayin'~
