Do you have voltage at distribbutor Black/Yellow wire with ignition switch turned On and while cranking?
Did you check if the distributor is turning when cranking?
I mean battery voltage. Use a DVOM to test the Black/Yellow wire for presence of battery voltage when ignition switch is turned ON.
Did you check if there is any fault with the timing belt?
This model does not use any cam position sensor. The CYP ( cylinder position ) sensor is in distributor.
Crankshaft (CKP) and TDC sensor are located on left side of engine. See diagram.
Was any repairs carried out prior to this happening?
Ok, let us start with the basics.
Perform the test on voltage to the ignition coil first. A faulty ignition switch could cause non starting as power is not supplied to the ignition coil.
While monitoring the dash indicators lights, slowly turn ignition switch to ON position. If lights flickers or goes out, the switch is bad.
Continue turning to START position, dash indicator lights should remain ON and steady. If lights flickersw, most likely switch is bad.
Above are visual test.
If above seem ok, test the ignition coil power supply with ignition switch turned On and while cranking. Attach test light to Black/Yellow wire and turn ignition switch ON. Test light should com ON. Crank engine, test light should remain ON. If light is not working, no power is being supplied to ignition coil.
