Checked replaced cap and rotor, there is spark! When turning ignition on there is no sound from fuel pump. So I decided to spray carburetor fluid into throttle body and it should start, but it does not.

Good afternoon.

Did you check the spark at the plugs?

Did you check the actual fuel pressure?

Yes, it does have spark at the wire and fuel pressure at 60psi. It should start when I spray into throttle body! Could it be crankshaft sensor? All sensors good and fuses.

No, if it was the crank sensor, it would not have spark.

Check your compression.
