Put the rotor on the dist and gently turn it while very slowly lowering the dist back in.
You need to make EXTRA sure you don't drop that pump shaft into the block.
I trust you have the engine cylinder #1 at TDC and are ready to slap it back together, but if you have more questions on that, let me know.

SOURCE: Pulling a fan clutch assembly from a GMC 4.3 water pump?

First remove the fan from the clutch. There should be four to six bolts holding the fan to the clutch. The clutch is held on to the pump with four bolts. remove the four bolts to remove the clutch. I've included a pic of the pump to indicate the four mounting holes. Not sure if the link will work.

SOURCE: 1996 gmc safari, 6cyl.-distributor gear broke.replaced.can't time

Roll the engine around until the compression stroke on number one cylinder (both valves are closed) and stop on top dead centre. The rotor should be pointing to the number one terminal on the distributor. If it is not extract the distributor and replace it with the rotor pointing to number one. That should be it. Hopefully their are no other issues relating to the original breakage so you should make sure the new distributor is spinning normally.

Remove the distributor cap mark #1 on the distributor housing turn to the number one postion and look at the shaft on the distributor by raiseing it above your head notice what positon it is at 1 oclcok 6 oclock or what ever the postion, now go back tothe block and turn the shaft in that direction so it lines up then turn the oil pump shaft 1 tooth or 1/8 inch oppisete direction gears spins. then place the distributor down in the hole not moving it from it's postion then lower it into the engine and turn it 1/8 inch counter clockwise as it drops allow the rotor to turn freely if it does not drop down turn the distributer one more tooth by raising it up so you can feel the teeth move one tooh then drop again you may have to wigle the distributor rotor shaft to get it to fall in. hope this helps. and have a six pack and walk away for an hour and try again.

How do I get a 4.3 back in time after removing distributor?

If you got the distributor in at least close to where it originally was, leave it in for now. You will have to find TDC for #1 cylinder by turning crankshaft until you see and line up timing marks. When you line up the timing marks, you will be on for #1 or 180 degrees off. You will able to tell by pulling the cap and seeing if it's pointing at #1(or near it). When you're sure you are lined up TDC on #1, pull the distributor, noting how much the rotor turns counterclockwise(CCW) when pulling dist out. Now hold the dist housing in the position you want it to sit in the block( determined by where #1 spark terminal will be), the rotor should be CCW about 1 1/2" from the #1 term, then lower dist housing down while watching the rotor turn clockwise and line up with the #1 spark plug terminal. The dist housing will be flush with block if done correctly. It takes some practice, but as long as you get #1 lined up at the crank timing tab and don't disturb it, you can play with the dist all day. The trick is, you have to get the oil pump shaft lined up with the drive tang on the bottom of the dist. You can use a long flat blade screwdriver to turn the oil pump shaft to the right clock position so it lines up when you drop in the dist. Remember to hold dist housing steady when lowering and let rotor turn into position. Good luck.

My 99 gmc 5.7 vortec got turned when the distributer was out now the oil pump shaft wont line up to put the distributer wont line up .. whats the best way to line everything back up and get the timin

If the Pontiac engine is similar to the small block Chevy, you have, I believe, a hexagonal shaft that runs from the end of the distributor shaft down to the oil pump. This is turned when the distributor shaft is turned by the meshing gears on the camshaft and distributor shaft. I would say that you are probably going to have to re-time the engine. Find TDC, then replace the distributor. It won't matter a whit to the oil pump if the gears are one or two teeth off, but it will matter a great deal if you distributor is not installed so it can be adjusted a few degrees when you get to "fine timing" the engine.

You should be able to download information on how to time the engine (finding TDC, etc.). Failing that, a trip to the library may be in order.

Vortec oil pump on a gmc jimmy

Don't start the car !!!

Can you see the part from the whole where the distributor goes ?
If you can you may be able to fish it out.
Your distributor has a drive shaft that goes from the dist to the oil pump in the oilpan.
Hopefully it is sitting on top of the shaft.
Their are know oil lines at the bottom of you engine, everything is internal.
If you cant fish them out from the top, the oilpan will have to be removed.
I think your best bet is to try to remove the pieces from the dist hole with a magnet on a shaft or maybe very sticky tape on a shaft.
Good luck, Robert

My car is 2004 Chevy Blazer, 4WD 4Dr, 4.3L. I changed intake manifold gasket today. When I pulled off the distributor, I didn't mark the position of the rotor, distributor and lower manifold. I thought...

Turn the engine over and bring #1 piston to the top of the cylinder then remove the dist. cap and be sure the rotor is pointing to #1 plug wire in the firing order. Turn the oil pump shaft with a screwdriver so you can keep the rotor pointing to #1 in the firing order set the dist. You have to pay close attention when you set the dist to the oil pump shaft or you can get it a half tooth off and car will backfire when you start it. Good luck

My rotor is pointing to 8 insted of 1. Which is 180 degrees from 1, what do i do l.o.l. the two holes on rotor only allow it to go on pointing to 8 and the wire to the dist.wont allow me to turn the...

I am assuming that you have had the distributor out, have reinstalled it, and are now trying to get your engine ready to start. If you have installed your distributor 180 degrees out, you need to lift it back out of the hole, turn your rotor 180 degrees and reinstall it. NOTE: by doing this, you will probably turn the oil pump drive slightly. This will make it impossible to drop the distributor right in. You will need to either turn the pump shaft (if you have the appropriate tool), or go around patiently with your distributor, setting it down in one notch at a time, until it is in the correct position. BTW, I do not know of any GMC product where #8 is 180 degrees from #1, so don't go any further unless you are sure you know what you're doing. #8 is usually right next to #1

I replaced the module but my distributor wont go back on straight

Oil pump drive inside distributor gear is not lined up with the slot in pump drive shaft. Lift and turn one tooth at a time. When slot lines up dist. will drop all the way home. At this point it is in corectly or 180 out. If so, lift and rotate 180, pump shaft and gear should line up again.

In what direction should the slot in the oil pump drive shaft lineup with when reinstalling it after cam replacement? engine is 5.9L from a 2002 Doge Dakota

the slot is irrellevant. when the number one cylider is at TDC the ignition rotor will point to number 1 spark plug wire terminal on the dist cap. as long as that lines up, you are good to go. if the dist wont seat down all the way, get a large straight screwdriver and turn the slot so the dist will seat all the way down. the slot is in the oil pump shaft as you know but the oil pump doesnt care about timing, it just pumps oil.
