howdy i've had several different codes show up on my truck recently i was hoping somebody could tell me what they was p1693, p0230, p1689. i recently added an edge juice and around 2-3 weeks later a fass. i had a problem with the fass building pressure. i wasn't driving the truck, but it took me a couple of days plus bumping the starter over & over to get pressure, also the truck runs fine i've got around 15 psi on fuel

 

Dont no bout 1689/1693, but 0230 shows 2 b "fuel pump primary circuit malfunction" maybe sum1 else will no bout the othr 2.
