I had a similar situation. Started 2 years ago when the truck stopped and the garage said it was the fuel pump. They recommended replacing the complete sending unit. Used Napa parts. Ran for a year then just quit again, same problem - no fuel being sent. Took it back to a diffirent garage and they replaced the fuel pump again. Ran for about three months and quit again. Diagnostics indicated a fuel pump so we did it again. Quit 2 days later. This time they found a loose wire between the sending unit and the wire harness. Seems third party sending unites have a cable to connect the unit and the harness. manufacturer sending units are hardwired into the unit and plug into the harness. We could not buy the connector cable by itself so I had to buy the full sending unit to replace it (I'm over 2,000 dollars at this point). Ran good for 2 weeks and now it quit again. Maybe someone else can offer an explanation.
All fuel sending units would be found inside the fuel tank.
There are two sending units on my 1999 2.0 mystique.One is located on top of the engine and real easy to get to.The other one is buried below the water pump and getting it out is very aggrevating.I spent about $200.00 trying to figure out why nothing seemed to fix it then one mechanic showed me the problem.One of the sending units may be working and one not working.I would suggest that you replace both of them at the same time.
either replace the sending unit or the dash gauge, that is if there is electricity getting to the sending unit.
It developed an leak and then for whatever reason sealed itself. Replace the oil pressure sending unit.
I drop the tank.
The coordinates of a point two units to the right of the y-axis and three units above the x-axis would be (2,3).
The best way to help repair the shelving is to just buy new shelving units. This would allow you to replace the units without worrying about damaged units.
Oil sending units commonly fail over time from vibration. Most units have mechanical moving internal parts that overtime can get jammed or break all together. Its very common.
In most cases it's the sending unit in the gas tank at fault. It would require dropping the gas tank to replace the sending unit.
Nothing! Sending units are typically made specific for each vehicle. As there aren't many sending units around for this type of vehicle, I would suggest checking your local scrap yard. Nissan Dealerships want about $190 for one of these, that's if they have it. You can always take your unit to be rebuilt, or do it yourself if you have the facilities. These sending units tend to corrode around the terminals on the top, causing the sending unit to stop working. You can fix this by cleaning the unit, and soldering the terminals back on. Just make sure you take care, and do this far from the open tank. If the terminal closest to the rear of the car is corroded, This is the ground. Solder the connection and cover the contacts and back of the terminal with dielectric grease. Easy fix! If your broke the steel lines coming from the sending unit your pretty much SOL, so start looking around!
If that is all that is wrong and you know 100% that the sending unit is bad, then my advice is to replace it. It is a cheap fix and if you do not replace it you have no idea what your actual oil pressure is. This could cause you to drive around with no oil pressure which would destroy your engine. Just replace it and then you can rest easy.
The sending unit is likely bad; replace it, per repair manual.
