I have tested for pressure at the schrader (sp) valve and got some spray. Should there be a constant flow when turning over the engine? What could be the cause of the 24 hr delay? When it quits starting, it starts again the next day. Can this be related to the regulator not building pressure?

Also, I just went and looked for the light above the fog lamp switch...it was there so that should eliminate the key issue, correct?
