i know this is kinda off topic but how hard is it to find a 94 1500 with red seats, carpet, dash, etc?? my dash is messed up.(i know its common in dodge) and my center fold up seat is broken (due to a break in). is red like a rare color?? the outside is factory white.

you oil psi should be higher than that... mine at first start up is around 70-75. then after is gets warmed up it sit at around 40 at 2k rpms, and about 15 at idle.

i got a new pump. i think the shaft that goes into the top of the pump is bent, but then i think it would break and not work

Or trash the new pump...... your pressure is too low. Put a mechanical gauge on it, and see if the gauge in the dash is telling the truth.

That's bad.

Did you use a stock pump? High volume? Oil level up to snuff?

I am thinkin' you are going to need to drop the pan again, and do bearings....... either that, or rebuild the motor now, while it is 'cheap', and you DON'T have to replace things like the crank, and rods.....

i used a stock pump, i hope the tube for the gauge isnt just clogged. when i first started it today it ran at about 70psi.. then is just slowly dropped. my pick up tube was all dirty and i think something got pass the pick up tube and clogged the gauge.

Pull the tube, and clean it out. See if that doesn't alter its attitude.
