My 98 Nissan Maxima was hooked up to a emissions machine and it said I had a bad knock sensor, which i heard was a common problem. It also said that cylinder number 5 was misfiring. i just got a tune up...

Did you change the fuel filter. The fuel additive you used will not get the water out of an old fuel filter. Excessive water in the fuel could cause the misfire. The Maxima is probably due for timing belt due to age. Missing teeth on the timing belt will result in timing walk. The knock sensor is probably getting pre ignition signals. Look at the belt and get the fuel clean and go from there. (Do an OBDII Scan)

Water in fuel light just started to come on intermittently. Changed the fuel filters 3 weeks ago or 7500 miles back. Had never changed the filters on fuel or transmission since the first 80,000 miles....

The change in temperature from Las Vegas to Alaska could have resulted in condensation building up in your fuel tank. Also you could have gotten some diesel fuel contaminated with water. The transmission oil should be changed as per manufactures suggestion or at least every 50,00 miles especially if you are towing.

The only fuel filter is in the fuel/water heater/sperator. If it is dying, the glow plug circuit should be checked first. The glow plug light should illuminate for around 10 seconds. The next thing I would check would be the fuel pressure going to the fuel/water seperator. Let me know what you find and if you need diagrams let me know.

My truck began to stall and quickly lose engine power as I was driving yesterday. I can turn the engine on but, it instantly turns off again especially when I try to rev the engine. What could the p

You could have a dirty Fuel Filter, try changing that first since it's the easiest and cheapest to do. You'll find the filter i believe on the inside if the frame under the drivers area. The only other thing i can think of is a fuel Pump going bad and not producing enough fuel pressure.
Best thing, start with the fuel filter and get the truck scanned for any DTC codes.
Good luck and hope this helps.

Fuel gauge

Water in fuel
During refueling, it is possible for
water-contaminated diesel fuel to be
pumped into your tank. Your vehicle
fuel system is equipped with a fuel
filter/water separator to remove water from the fuel. The WATER IN
FUEL light will illuminate when the ignition is turned to START (as part
of the light function check) and when the FCM/HFCM has a significant
quantity of water in it.
If the light illuminates when the engine is running, stop the vehicle as
soon as safely possible, shut off the engine, then drain the FCM/HFCM.
Refer to Draining the FCM/HFCM and changing the fuel filters in the
Maintenance and Specifications section of this supplement for the
drain procedure. Allowing water to stay in the system could result in
extensive damage to, or failure of, the fuel injection system

Just driving and car would stop...3wks ago oil/trans oil changed..someone said my fuel filter or pump...after letting it sit for a while it would start and run fine...did it again had my fuel filter...

The coil pack modules are a common red flagged problem when they heat up. If you could get some one or your self to take the part off, easy to do, you can get it tested at your local napa for free. Other wise, if you give me more information, I may or may not be able to help.
