Bad coil? Bad distributor cap? Bad distributor rotor?
no it will not...
The spark plug gap on a 1989 Toyota pickup with a 3.0 liter V6 engine should be set at .032 inches. The best spark plug for this vehicle would be an iridium plug.
The ignition module that is in the distributor is probley bad.
most likely the fuse is blown
bad spark plugs or bad wire connection to the spark plug
Could be spark in the motor, or the distributor and rotor need to be replaced.
timing chain has too much slop and rubs side of timing case
I would replace the ignition module in the distributor.
Short in the wiring or the circuit is overloaded and pulling too much current. Can also be a loose connection causing a spark.
Kickdown cable needs adjusting.
I need to change the fuse on the horn and hazzard lights on 1990 toyota pickup, what amp should I use?
The engine needs fuel, compression and spark. You are missing one of those.
