Hello everyone
I have a 96 Ford Bronco 5.8 v8.
4x4 with 247,000 miles
The distributor pin that holds the gear is missing when I pulled it out of the block.
Obviously the car won’t start.
The mechanic mention the oil pump seizing could be the reason of this . Need some guidance please . Also would it be possible for me to install a new distributor , timing would be a issue?

My concern would be where’d the pin go and did it do any damage? I would, at a minimum, drop the pan and inspect. While the pan is out, you can change the oil pump if your mechanic is right that it seized. If you either find the pin or everything looks ok, you could button it up and install a new distributor and pray for the best when you fire it up.

Yo Stormy97,
Suggest you add the recent additional info we discussed in our Conversations (formerly "Private Messages"), especially;
"Oil pressure gauge moves back and forth so fast you can’t see the needle , but only when hot.
I thought it was the sending unit.
The mechanic said the pump is working"

Following is my usual intro to new members with the Best Year Bronco 😁:
Find out if speed control, if equipped, recall work completed by a dealership. Call local dealer or register and view status @ Welcome to Ford Owner | Official Ford Owner Site; or @ Recalls Look-up by VIN (Vehicle Identification Number) ... have VIN ready.
"Summary: ON CERTAIN PICKUP TRUCKS, PASSENGER VEHICLES, SPORT UTILITY VEHICLES, AND MOTOR HOMES CHASSIS, THE SPEED CONTROL DEACTIVATION SWITCH MAY, UNDER CERTAIN CONDITIONS, LEAK INTERNALLY AND THEN OVERHEAT, SMOKE, OR BURN. THIS COULD RESULT IN AN UNDERHOOD FIRE."
To confirm current status, use this guide by jowens1126 @ 93 & 94-96 Cruise Control Recalls Repair
Note that the 93 recall is different than the 94-96 recall.

As Petersonat mentioned the important question is where is the pin. you can also go to a chain auto parts store and borrow and oil pump primer tool. that might also tell you if there's any issue with the oil pump.
either way, you'll need to drain the oil to make sure you put hands on the pin.

a very inexpensive haynes manual - probably also at your auto parts store - will guide you through distributor install and timing.
there are some great write ups on this site as well

As mentioned, get a pump prime tool, take off the driver side valve cover and spin the pump. If it works, drain the oil and maybe you will get lucky and the pin will come out (strain the oil as it comes out).

If it doesn't come out....decision time.

And yes, once you get it all sorted, you'll have to find TDC on #1 and stab the distributor in with the rotor pointing to #1. If you are lucky it will start and run enough to put a timing light on it.

Remember that the Oil Pressure "gauge" is not really an analogue gauge, it is a switch, it grounds the signal when the oil pressure is over 6 PSI.
It's easy to change and cheap too, you may need to get a special Ford oil pressure socket as the gauge had a thin metal shell and a regular socket can distort the shell. Also remember that the oil pressure switch sender has a tapered pipe thread, you can damage the gauge or the boss it sits in if you overtighten it. The gauge is grounded through the threads, too much Teflon tape on the threads will insulate it from the block and render the gauge useless. A little Permatex thread sealant is all that is needed.
