Have a service engine light that I accidentally cleared so I don't know what the code is. Recently replaced the fuel pump which was dead. See the picture of the fuel gauge attached, its stuck it full. Any ideas? This is the car off but the same thing when it is on.

Guage cluster.

Miswire in the sending unit, likely

or bad ground

Talking to my grandpa, the gauge is always like that.

Any ideas what can cause the Service Engine Soon Light?

It desperatly needs an oil change.

I accidentally hit the wrong button and cleared any codes that may have been there. It didn't show any though.

Without having any information on the car, there are myriad things that could cause an SES light. Drive it for a while and see if the light pops back up.

What controls the service light, anyway? Is it also the CEL? If not, it may just be done by milage since it was last reset.

if the light isn't flashing, then the car is safe to drive. drive it and see if the code comes back.

as for the fuel gauge, it's either the sensor, the wiring, or the gauge in that order. the sensor might just need to be cleaned. depending on the gauge, the resistance of the wire could directly affect the reading. given the age and value of the car, I'd consider leaving it alone and just get in the habit of filling the car up regularly. but then I used a bad temperature gauge as an excuse to put in an aluminum radiator, replace the water pump, coolant tubes, etc. in my previous AE86.

I don't know how long you have owned the car, but when I first bought a Miata, I was coming off owning an RX-8. so when I drove it for a day and the gas gauge was stuck on full, I thought the gauge was broken. so I topped the car off and it cost me $2. so I also wouldn't rule out a 1998 Nissan Sentra getting more than 8 MPG being the cause.
