Yes, any of those can cause a no spark problem.
Check coil or distributor cap or rotor SORRY NO DISTRIBUTOR,ROTOR OR COIL ON THIS ENGINE HAS A POWER PACK ONLY WHICH IN FUNCTIONING.?
probably needs tune up. plugs, wires, distributor cap, rotor, button, maybe coil
If it has a distributor, check the rotor button for a burn mark underneath. The high energy coil will sometimes burn a hole through it causing the fire to ground. Replace rotor button.
Rotor buttons are inside a distributor.
The rotor button is inside the distributor cap.
An electronic ignition tells the spark plugs when to fire to ignite the fuel. In older cars this was done mechanically by means of a distributor and rotor button.
check/change the ignition components(plugs, wires, distributor cap, rotor button)
there is no distributor on a 98 rav. therefore no cap or rotor. replace the plugs and wires and the tuneup is done
If you have spark at all but one plug, the problem is with that plug, wire, cap or rotor.
To change the distributor cap and rotor button on a 1999 5.7 Vortec engine, first disconnect the negative battery terminal to ensure safety. Remove the distributor cap by unscrewing the retaining screws and carefully lifting it off, noting the wire positions for reassembly. Then, take out the old rotor button by unscrewing it from the distributor shaft. Install the new rotor button and distributor cap, reconnect the wires in their original positions, and finally reconnect the battery.
The spark travels from the coil to the distributor then from the distributor to the plugs. So if you have spark going into the distributor but not coming out to the plugs, I would blame the distributor cap and rotor being at fault.
To much resistance in the spark plug wires. Start fresh with a new distributor cap, rotor and spark plug wires. Also be sure you have the correct spark plugs installed.
