Depending on the vehicle, you could have a alarm or security lockout happening. There is a relay in the circuit that is not allowing these items to operate. There also could be a wire broken (a short) that is not allowing the pcm to get power. You have not specified whether you are getting power to the pcm or not so you will have to get a meter or test light out and see if you are, and if the is not power there, then follow the wire or schematic and find the fault.
Can you crank the engine?
Have you check the relay for the fuel pump?
Have you checked the power for the fuel pump relay?
have you replaced and or tested both coils? are you getting no spark on the intake and the exaust sides?
if you are not getting spark in your coils iti could be the crankshaft sensor im not a mechanic lol but i have the same problem with mine im trying to find out how to install the sensor i replaced the coils and the ignition module and still no spark
your catalic conv. is done and/or o2 sencor it both happen to me
This question is referring to a vehicle's ignition coils (on gasoline engines). The reasons range from normal absorption of engine heat from the compartment to the coils receiving excess loading/voltage. The latter can be a sign of impending ignition system failure
If you have not already replaced your spark plugs then do so, you might also want to check the coils while your replacing plugs if it still runs rough with loss of power try sea foam to clean your crank shaft and your injectors and all the fueling system.
A system where the Ignition Coils are located on top of the spark plug boots... Coils powered by the ECM.
Both the fan and pump have coils.
It depends on if it is a coil on plug set up or not
They can be dirty or the system can be low on freon.
The timing or crankcase sensor needs to be checked and most likely replaced.
Change the coils they should be two black blocks on top of the engine..the coils could have gone bad.
Ignition coils are not normally repairable as they are sealed units. They must be replaced.
