Hello....I've had my 88 Maxima since March and a few months ago the oil pressure gauge stopped working..or at least it doesn't go above 0. There's also the coolant temp gauge, gas gauge, and charging system gauge, but they all work fine. I'm not sure how those kinds of things work and I'm wondering if anybody here does? I realize it may be a minor detail but it's a good running car (it's a Nissan) and I'd like to fix it so that I know when the oil pressure is down.

Also, my "low fuel" warning lamp does not come on, I'd like to fix that too, but it's a lower priority.
