a oil gauge reading maybe delayed until car starts and builds good oil press.Did you check for spark
was car running good before this happened? Do you have a rpm reading when cranking car?

in order to check the oil pressure, you have to remove the oil sending unit, then screw in the adapter of the oil pressure gage, and then remove the start relay or fuel pump relay from the fuse and relay box, under the hood on the drivers side, and then crank the engine over 3-4 turns, and then record the oil pressure, and then disconnect the oil pressure gage, and then re install the oil sending unit, replace the start relay or fuel pump relay, and then start up the car, and check the oil sending unit , to make sure it is not leaking, if your oil pressure checks out within the specs, then you are fine, if it gives you a low reading, then you could have a bad oil sending unit , or a oil pump going bad on you. i would replace the sending unit first, then see what the gage shows.

For 1989 Nissan/Datsun 300ZX 3.0L FI 6cyl the Flasher is located in front seating area, driver side, under dash, above brake pedal, mounted on pedal support bracket .

Hope helps (remember rated this).

You need to lubricate the o ring prior to fitting the injector. Without the lubrication the injector does not slide into the fitting and can roll in the groove and get snagged and damaged. A thin film of engine oil will fix it but also check the sleeve where the injector sits in case it has a burr or was nicked during the removal process first time.

MY S-10 IS LEAKING OIL. I WANT TO KNOW WHERE THE OIL SENDING UNIT IS.

HI, the oil pressure sending unit may be malfunctioning at this point. this will cause erratic readings. if your oil level is proper and there are no apparent oil leaks, you will need to replace the oil pressure sending unit. this will fix the erratic oil pressure readings.

Concerning the gas gauge. this device also has a sending unit that sends the correct fuel level reading to the gas gauge via wire transfer. this sending unit is located and attached to the fuel pump assembly inside the gas tank. replacing this device will fix this issue as well.

Please rate and god bless:)

rear main seal is the leak to fix: drop transmission remove clutch, drop oil pan and replace seal. seal is about 30 bucks, if your not auto savy id let a shop do it.. prolly around 800 tho...

You need to invest in some jack stands or take it to a mechanic shop to get it off the ground so you can work on it.

No spark issue can be from a number of causes. Most likely the crankshaft position sensor. It is sensitive to minor damages. check position of the teeth. If bent carefully straighten. Also can be the ECM (main computer) On cars with no fuel pressure check oil sending unit because a faulty one that tells no oil pressure will make computer cut out fuel pump operation.
