from the sounds of it i think my pressure is ok going by what jeremy fitch posted and that i have a cmfi or csefi system. i will follow that advice although some has been done already.
what do you mean by holding? is that what pressure would read after idling for 10 minutes or so? could it be a relay or a clogged return line? how do you know if a fuel pump is intermitantly bad? and what's an ecm?
thanks in advance for the help everyone.
