The oil pump drive is off the intermediate shaft and that is driven by the timing chains. Unless you want to take apart the chains and spin the int shaft itself, there isn' t a good way to prime the motor.
Or just try this:
Just disconnect the bulkhead plug just behind the coil pack, you know the big round thing with all the wires. Crank the engine over a few times, 10-20, reconnect the plug and start the engine.
Or this:
Look on back of block there is a metal cap held on by two bolts. Take that cap off and pull out the top gear then find a socket that fits the top of the oil pump driveshaft. Put it on a power drill with a long extension stick it in the hole onto the driveshaft and spin it, cover top of whole around the extension with a rag so it doesnt spill. This will prime the whole motor, if you do it with head open you can see the oil come up through the lifters

SOURCE: Pump Priming Problems.

you should try to pack the gears and pump cavity with petroleum jelly which will prime the pump and the oil will then displace the jelly. If you use any other kind of grease, the oil will not be able to displace it so make sure you only use petroleum jelly. This is the stuff used in the medical field but works great for this purpose too. Let me know how it goes and whether you have any further questions. Thanks and good luck

You have hooked up a manual test gauge to the oil pressure sensor/sender port and verified you have no pressure? Did you prime the oil pump before you starter the engine?

How do i prime the engine after rebuilding 3.1

What kind of engine is it? As far as the pistons go you should have used motor oil or the like on the rings when you installed them. If you're talking fuel and it's a fuel injected engine, you shouldn't have to prime it as the fuel pump pressurizes the system and shouldn't need any other source.

Had the pressure bypass valve malfunction on my 2.5 jeep put new oil pump in and with 45lbs. Oil pressure motor still sounds dry of oil,what gives?

it's not priming.
that grease trick helps.
is this some china pump off fleabay or a real jeep pump..???
did you do the below.:
1: the grease sure. and then prime the filter and the gallery behind the
2: With fuel and spark defeated, and spark plugs removed then with pressure gauge attached to sender port, did you crank it to get max pressure (my guess is this is the step you are posting on.)
i never start any engine, (after majors) unless i get #2 to work first the number 3, which is top end oil checks.

the pump is no priming.
In pro shops they make up a priming tool. so new engines are never
started, 1st time dry, ever.
one way is just a tank full of oil and shop air, and 2 valve.

maybe the new pumps relieve valve is stuck open, fully.
i rebuild my own classic engines, after all that work !!! i never
ever, skip these steps.
and for 100% sure, good pressure, and top end oiling on any major work.

Oil pump of mitsubishi montero 1998 is not functioning

If you have a timing belt on the engine it is a good bet that there is a belt that also drives the oil pump. Have you done anything to the motor like a rebuild. Missing/loose oil pick up pipe. Pump not primed before fitting. The oil goes first to the filter for cleaning before going to the rest of the engine so your problem will be in the pump drive or pick up area. Have you put oil in the sump.?

How long and easy is it to rebuild oil pump on 94 grand caravan 3.8l

Don't bother. Replace the unit.
3.0 liter
The oil pump assembly used on this engine is mounted at the front of the crankshaft. The oil pump also retains the crankshaft front oil seal.
  1. Remove the accessory drive belts.
  2. Remove the timing belt cover and timing belt. Refer to the timing belt removal and installation procedures in this section.
  3. Remove the crankshaft sprocket.
  4. Remove the oil pump mounting bolts (5), and remove oil pump assembly. Mark mounting bolts for proper installation during reassembly.

To install:
  1. Clean the oil pump and engine block gasket surfaces thoroughly.
  2. Position a new gasket on pump assembly and install on cylinder block. Make sure correct length bolts are in proper locations and tighten all bolts to 10 ft. lbs. (14 Nm).
  3. Install the crankshaft sprocket and timing belt. Recheck engine timing marks.
  4. Install the timing belt covers. For more details, refer to the timing belt cover installation procedures.
  5. Install the accessory drive belts.
  6. Refill the crankcase and start the engine.
  7. Check for correct engine oil pressure and for any oil leakage.
3.3 and 3.8 liter engines

  1. Disconnect the negative battery cable. Remove the dipstick.
  2. Raise the vehicle and support safely. Drain the oil and remove the oil pan.
  3. Remove the oil pickup.
  4. Remove the chain case cover.
  5. Disassemble the oil pump as required.

To install:
  1. Assemble the pump. Tighten the cover screws to 10 ft. lbs. (14 Nm).
  2. Prime the oil pump by filling the rotor cavity with fresh oil and turning the rotors until oil comes out the pressure port. Repeat a few times until no air bubbles are present.
  3. Install the chain case cover.
  4. Clean out the oil pickup or replace as required. Replace the oil pickup O-ring and install the pickup to the pump.
  5. Install the oil pan.
  6. Install the dipstick. Fill the engine with the proper amount of oil.
  7. Connect the negative battery cable and check the oil pressure. Check for any oil leaks.
for the 3.3 you can rebuild, 3.0 - replace.

How do I prime the oil pump on a 1985 Pontiac Bonneville?

It is quite possible. Most cars will have a low oil level/pressure safety switch that will not allow the car to start. As far as rebuilding the pump, the necessity only depends on your budget. It may be cheaper to rebuild it, or buy a rebuilt unit. If you do choose to rebuild it, I would definitely invest in a Haynes, or Chilton's book for your car.

Getting ready to start a 1973 chevy 350 that sat a while.i went to prime oil pump ,and i only get oil out of rocker arms on driverside.oil pump is pumping perfect.motor was pulled out of a truck and was...

You should be fine. the same oil port feeds both sides of the lifter galley, it just splits and goes to both sides. fire it without the valvecovers on it or at least that side. you will have oil shortly. many different reasons for this. try to turn the engine 180 degrees if it really bothers you. its good to be thorough like you are but you'll be fine.
Good luck.
