Finding tacho pulse wire. I own a 1992 Toyota Corolla which has a 1600cc fuel injected motor with electronic ignition. As a base model my car does not have a tacho and so buying a digital tacho I need to know how to find tacho pulse wire coming out from electronic ignition module.

How do i fix the tachometer?

you have an in cluster factory engine tachometer (RPM)?
the tacho is meter in the cluster and does not use speedo parts or its cable.
its just a meter that needs power, ground and spark tacho signals
if all 3 are good, the meter is bad. period.
the tacho signal goes to the ignition coil minus lug, and will good, as engine runs. so... wires bad, to tacho or tacho bad.
ever price a new one? or even used? $100 used?
you willing to pay that much for just a factory tacho?

there is NO speedo cable. this old 93 is electronic, (rare on most 93 cars made, toy is advanced)
here is the proof, amazing how books dont lie....
there is a speed sensor.
the tacho and speedo use the same power and ground
leaving just one wire,r-g red-green RPM sig. pin 5 of cluster
an is SPARK primary sig. so if only tacho is dead.
then the tacho is bad, or that pin 5 wire is dead.
got you to just 2 possibles.

Computers ecu not working 89661-2B381

Pick-up after the inspection results are as follows: 1. Engine starts without high-pressure fire; 2 engine nozzle on the fuel injection pulse measuring less; 3 Turn the ignition switch, the engine warning light does not shine (under normal circumstances, turn the ignition switch, engine fault light should be lit. electronic control unit after starting the engine electronic control components for 4 ~ 6s self, confirmed there is a fault fault lights lit, no fault fault light goes out). Taking into account the car ignition and fuel injection are directly controlled by the ecu, ecu lack of work is likely to be unable to work due to voltage.

I have a 1992 Toyota Corolla.Engine capacity 1600cc Does it need to change its crane belt?

Toyota recommends changing the timing belt every 85k which is a god idea in that Toyota builds interference motors. If it hasn't broken it is a good preventative maintenance. Also it is a good idea to change the water pump while you are in there as this is a task to get to when replacing it and can cost you just as much as replacing the timing belt.
