Not normally no. In a rare occasion where the plug wire has shorted, or leaked, high voltage to the injector wiring, it could have damaged the CPU or power fuse or relay, but that would not be very common.
Probably the spark plug or spark plug wires, I would try that first.
Check spark plugs and wires
i have a 92 mercury carpi i have fuel i have spark but will not start i do not have power to my injectors not sure where to start on how to get power please help
The cracked plug can cause the wires to spark and cause a fire. When the wires are plugged into it where the crack is the wires can touch the socket and cause the fire.
may want to check and see if the spark plugs had the proper gap. also if you tried to upgrade the spark plugs like buying platnium or split fire..those upgrades require a upgraded coil It could be distributor (if it has a distributor), injectors, valves or a number of other problems.
Because of the heat/fire with electricity would start it to make/create a chemical reaction which would have it smoke.
depending on what type of fuel delivery, check fuel injectors or tbi
I would start with replacing the spark plug wires and spark plugs (if you did not do that for a while). If does not help check the coils or distributor depending on what you have.
it has to be the distributor cap or rotor or wires...plug wires.
bad spark plug wires, low battery, broken rotor in the distributor
Bad coil or bad coil housing.Also could be leaking fuel injectors. I would check the fire to the plugs.With no fire there is no spark and fuel is just piling up in there.
The PCM in your car provides the ground for the individual cylinders to fire, so if you have new wires, coils and plugs then I would say you have a bad internal ground inside of your PCM not allowing #5 to fire. It works the same way for your fuel injectors, the PCM provides the ground for each individual fuel injector to fire.
