Check your battery connections at the starter. It may not be getting the needed volts. Just make sure they're clean and tight at the starter and the battery both. Good luck!

buy the manual. and RTM,
and yes, Air , water, and on a stock car up to 3 coolant sensors.
The ECT runs the ECU. tells ECU coolant temp.

on most 93 car, the Guage has its own sensor, (isolated)

Won't crank or won't start ?

Sorry we do not have parts locator services here.

you said it cranks then you said it wont turn over if it wont turn over you might have get the engine to hot and seized the engine please spesifiy if the engine turns over or not

go to a place like autozone or pepboy autoparts
tey will the code retriver myth have a factory code
that service is free,if they are code they will explane
wath next

check all your relays with an ohmeter to make sure they all operate. A code would go off usually only if it is an electrical problem. If you are getting fuel and fire, and no codes it is most likely a relay. If you did have codes then I would say sensor. So check those relays

Yes a harmanic balancer from tha corolla is the same thing. I had to do the same thing with my 95 geo. It works out to be a lot cheaper buying for a toyota than a geo.

my mechanic scribed mileage onto the radiator fan housing when the timing belt was changed
