1993 Ford Ranger 2.3L... I just finished putting everything back together after replacing timing belt and crank sensor. I was able to match timing marks on crank and cam pulleys with no trouble but I dont think i got the oil pump pulley right. Everything i read said that timing didnt really matter for the oil pump pulley, but when i started it, it sounds like its not getting any oil. Before i take it apart again can someone comment? There is a mark on the oil pump pulley but i dont see a mark to match it to on the timing cover.

 

AUX gear(oil pump gear) will have a diamond mark, it should point to 12:00 when other marks are lined up.

This is not oil pump timing, it for the Cam Sensor that reads the AUX gears position, Cam sensor is on the back side of the AUX gear, mounted to the rear plate.
1995 and up 2.3l/2.5l all had Cam sensors
1993 may or may not have one, Calif vehicles for sure had one but other states were hit and miss, it was for better emissions

Since you don't have a mark on the engines front plate I would say you also don't have a Cam sensor so no need to time the AUX gear

AUX gear drives the shaft that turns the oil pump and "they" are correct, there is no timing for that, as long as AUX gear is turning oil is being pumped

 

Hi, RonD Thank you for your reply. It does have a diamond mark but seems there is no cam sensor behind the aux gear. The aux gear pulley looks identical to the camshaft pulley, and theres nothing behind it. I would expect it to look similar to the crank sensor? Plus my oil pressure gauge is reading fine, so i think you are right, its getting oil. I am not sure why the engine suddenly sounds so noisy. I probably did something else wrong that i have yet to discover.

 

Cam sensor is on the outside but behind the plate thats behind the AUX gear

It can be removed without disassembly of timing belt system, it is on the outside

So not like 1989-1994 2.3l Crank sensor setup

And no you probably don't have that on yours

CAM gear and AUX gear have the same number of teeth, and Cam sensor reads the AUX teeth as they pass by it, timing mark on AUX gear denotes a "fake" missing tooth, a space in the pulses it gets from each tooth, so computer knows exactly where the Cam is at all times, this allows for better fuel injector timing, opening an injector only when its intake valve is opening so less fuel is lost on the sides of the intake/heads, also a better mix with the now faster flowing air as it is sucked in

 

wow, very informative thank you! Part of the reason I bought this project truck is to learn how to work on it, so i seriously appreciate when an expert shares knowledge like that. I think i figured out whats so noisy. There was a little bit of wiggle room on the crank sensor and i think i may not have lined it up exactly right and the tab from the harmonic balancer that spins through it is tapping against it.
