I have a 1996 Sidekick JX...use every day stop and go.  It began oil light flicker a month ago, even at cold start-up...now steady until high rpm on road.  Changed oil to 10-40 and replaced pressure switch...no change.  Has 178,000 miles...not unusual for any of my trackers or sidekicks..(love these cars)  Other than a new oil pump, any suggestions?   

Your pump probably has a stuck partly open pressure relief valve,
I had that problem and it ended up blowing my turbo in Moab 

You will need to pull the pump to fix it, so you might just want to
replace it with a new one while you are in there

Thank you...isn't the pressure relief port open once the pan is removed?  Could one take the retaining clip out and clean the spring & plunger etc from below...maybe spray a good cleaning oil up the shaft, maybe tap on it...(it's cold here and I am old)...but you are right...why not just go all the way and put a new unit on it.  dv

It's would be easier to remove the pump, if your truck is 4wd you will
never get the pan off unless you drop the axle.

The process is pull your belts off, fan, shroud, belt cover, you still will need to
let the pan drop some in front or you will have a leak, and there are 2 studs
in the front that need to be removed to get the pump off.

You will have to remove the timing belt, so it's a good time to change that
too, then remove the crank cog, remove the nuts/bolts that hold the pump
on and pull it off the crank snout.

Assembly is just reverse order, I probably forgot something steps wise along the
way, and I know it sounds like a lot of work, it's not too bad, but working in the
cold sucks so if you want to put it off for a while (unless this is a DD) you can
