Started the stang the other day and got nothing on the oil gauge. I just replaced the oil sender unit and I still got nothin. Does this mean that it's the gauge or is there something else I should check first?

Any other symptoms? Does the oil pressure idiot light go out when you crank it? Is it flickering? Any noises - knocks, rattles, etc.?

I'd invest in a quality oil pressure gauge and sender (a good investment anyway as the stocker is pretty virtually useless). See if that remedies the problem. If you're showing low pressure with a good new gauge and sender - better stop driving it until you figure out what the problem is as low pressure usually causes BIG problems.

Car cranks and starts fine, no idiot light, plenty of oil in it, etc. It's not low pressure though, no life from the gauge at all.

I do get some sort of wobbling sort of noise once in a while when the car is at idle (can feel it in the drivers side floorboard), drives me nuts looking for it but I don't think it's related. Wish I knew what was causing it though. It usually stops doing it by the time I get out and start looking.

Is that possible when not moving?

sure, if one of the hangers is broken there will be play in the system and while idling it could def. move it around. i would get under there, with the car off and cool, and try and shake the h-pipe to see if it moves, if it does that's probly it.

get a mechanical gauge (10 bucks at parts store). hook it up in the engine bay to see what gives. or get a nice gauge, and make it permanent. dont guess.

Electric or Mechanical either one would be better that stock. I went with an electric autometer so I didn't jave to plumb hot oil inside my car, but the mechanical is supposed to be abit more accurate.

in this day and age, i think one is splitting hairs with debating elec over mech gauges. as long as it is a decent quality gauge, it wont matter practically speaking. what is more decisive, IMHO, is how much sweep you want (very few electric gauges have a 270* sweep), and as TS mentioned, whether one wants hot fluids in the vehicle.

Autometer's new electrics are every bit as accurate as a mech. gage and are available in full (270) sweep. but are expensive as H***!

Anyway, get a mech. gage, and if only to diagnose the problem, a cheap one will do fine.

Do not run the engine any more untill you know the pressure is fine!

I had the same problem with my gage... just went over this in the fuel gage thread. This could be a bad 'gage voltage regulator'. My oil presure would not register (but checked fine with a $10 Sun mech. gage) and my temp would read 1/4 up when engine was dead cold. Replaced the gage regulator on the back of the gage pod and it worked fine.
