In the fuel tank there is normally a float connected to the fuel pump with a little mechanism that sends a signal to your cluster telling you your fuel level
Test it to see if its functioning

Shift interlock system problem . Not the cable . Your vehicle has a safety system that won't allow the gear selector to be moved from park without the brake pedal pushed . Lock solenoid keeps gear selector from moving . Trying to force it will break something . Do you know how to test electrical circuits with a volt meter ? Here is a web site for free wiring diagrams http://www.bbbind.com/free_tsb.html
Enter the vehicle info. Year , make , model and engine size. Under system click on transmission / transaxle , then under subsystem click on shift interlock . Click the search button then the blue link. Park neutral switch , brake switch and the shift interlock solenoid , check electrical circuits .

electrical short in the system somewhere. Thats what is burning alternators. Probably in the charging system circuit.

old post.
no photo under hood, no joy.
yes, older cars , AC was an option.
yes, ac can be added to anything on earth at any time.
only cost is matter,
mostly nothing is impossible.
rare exceptions, ask NASA, they do this all the time. impossible.

old post
no engine stated, ?? which one? 4AFE or 7Afe (TOY ENGINE)
the harness will not allow cross wiring injectors
how did you do that?
the #1 injector is on #1 cylinder
and on #1 fuel rail port.
the #1 cylinder on inline engines, the crank pulley end.
if you need wire colors, we can do that too.
or log in to mitchells DIY and read. that.
here is the 7aFE wires
B-O is 12vdc power key on, the ECU fires the 4 on right.

sure it can, but so can other things fail....
why guess, buy a $10 voltmeter and find it. no?
1: check fuse first. and if IMMO cluster light is OUT. (not immoblized by alarm)
2: if meter lost, try new starter relay, (wild guess 1:10 chances of a fix.....)
3: it can be bad wires bad, connectors, bad PRNDL switch, bad, key switch, IMMOBLIZER ACTIVE, added alarms. added remote start kits, called hacks by me.
what's there after 23 long years?
what to do....
well the steps are all easy in them selves each.
1: battery charged,fuses all test good.
2: does AAA autotow , jumper method work? jump starting car, with running other car. like all folks do, mostly, and for sure standed on the road.

3: did you hot wire the starter solenoid,"?
biggn lug to dinky lug? grrrrrgrrrrrrrrr omg the starter and battery are good. is this hard?
do so in park (wheels chocked) ok>?
the engine will not start doing this hot wire test.
a car keys in pocket SURE.

4: ok now you know for sure the stater works on the actual car. (we can bench test the too)
5:on this car, a Toyota Corolla in snake GM skins
we then check the voltages at the starter relay.
it has 4 pins.
2 are coil pins.
2 are power contactor pins.
we measure them cranking (a live test)
how the logic works here varies by "
a: what engine is there, unstated.
b: what trans, auto or stick>???????
c: if car was opted day one with that immoblizer.
but we can just test and let the truth win out.
lacking facts from you as to driveline actual.
Volt meter in hand, DMM set to VOLTS.
black lead of meter to battery neg post.
here are the relay pins.
the concactor relay input pin is 12vdc all the time.
it's at battery voltage .
the key switch sends 12vdc to the coil pin.
there are 4 relay pins in the drawing tell us what to expect.
pin 4 is battery voltage 12v if not, fuse blown.
as seen in the drawing.
pin 3 runs the starter solenoid (now dead)
pin 2 is grounded, 0v, cranked, if not ground bad
or IMMOBLIZER not happy, that P wire is immo
in the factory with IMMO added, the ground wire is cut, seen in the drawing.
pin 1, saving the fun for last.
i check pin 1 , yes, cranking,
11v to 12v good, if good, relay is bad.
if less than battery voltage or near 0 volts
that means the KEY Line to the relay is BAD, DEAD.
easy no?
if the line is dead, here, at pin 1,
then the clutch switch is bad, (got a stick shift)
or the PRNDL switch is bad, does it crank in Neutral> omg yes?
ok lets say pin 2 on the PRNLD switch is dead.
that means the ignition switch is bad.
but lets move on, to prove that, easy with a $10 meter, no?
at the key switch you find the ST1 pin dead. yes, cranked,
then move the red test lead to AM1 pin on key switch , its dead.
the fuse is blown or bad wring from fuse box to here.
all fuses in the drawing left side are 12vdc hot all times, both ends of fuse.
if not the fuses or wires are bad.there.

if the odometer does not stick, watch carefully , the 1/10s digit.
drive slow, no bumps when it sticks and watch ODOMeter
if odometer dont stick the needle side is, as all do this old.
for 90s cars, vast numbers stick and more every day
as owners hedge , gee $200 fix .or more.......
get a GPS speedo and use that, or glue on a cell phone holder
and use a free app, (GPS speed) to see speed.
there you go, all choices.
the cable has 2 ends.
head end if dead, the speedo and odometer stall.
the other end, has gear to trans tail shaft,
so it measures actually road wheel RPM and converts that to speed.
the cable can be broken on both end or the middle.
the bottom end can fail strip out or its gear go bad.
fixed them all, every which way but loose.
easy no? easypeasy-japaneezey
if the odometer freezes too, that means the cable end is bad.850403f4-cfb0-4822-8bea-bd0bef80f062.jpg

There is not reset to speak of, please explain what is going on.

im assuming your speaking of the engines internal thermostat ? if this sticks open (not likely) then temp gauge on car will never reach operation temp and stay low on scale ( entire purpose of thermostat in first place) now if your coolant fan switch sticks closed (very likely) then your fan will run constantly and only shut off with the key

also another condition that makes them run more often is that engine temp gauge is over normal (showing) and this is an indicator that cooling system has a problem and needs service

Bearings on a water pump failing on any car is a common problem! The water leaking from around the water pump area is the tell tale sign.........get it checked out and replaced as soon as possible to avoid further damage to the engine.
