help with friends 93 nissan maxima

[jodom15sc]

title kinda says it all, my friend has a 93 nissan maxima, its a total P.O.S.
First it starts to sputter and catch fire, i took care of the fire problem cause it was just a fuel line and did a tune up which helped sputtering slightly. Next came bad sensors and thermostat, ironically my ranger went out at same time and its a 99, fixed those easily.

but NOW the problem is just out of the blue his speedometer went out then 2 days later his odometer went out...i know how a speedometer works on my truck but not a front wheel drive nissan maxima.

So anybody have any clues to how to fix these 2 new problems? i figure loose wire or something.

i think they run off a magnetic sensor on those? not 100%though. they didnt go out at the sametime?

honestly knowing this kid, his car could blow up and he wouldnt notice
so they probably did go out at the sametime.
But where would the magnetic sensor be?

most likely on the transmission. like wear a mechanical one would be.
