Question about 2002 Nissan Sentra
You leave all coil pack connectors on their respective cylinders.
Usually the crank position sensor tells, the computer where the pistons are,by where the flywheel is,as it passes the sensor.
You leave all injector connectors in their number sequence.
Every vehicle uses different ways of pulsing the injectors. Not familiar with yours
Most likely NO,to the coils and injectors being tied together.
You can not spray fuel and try to ignite it, at the same time,it has to get into the cylinder and be compressed, one cycle before the spark.
You could switch injectors,and a relative did that, earlier this year, based on your theory. Sound thinking,a lot of work and not your problem.
Might add, that while your plugs may needed to be replaced,they had no effect either. Personally, never had a plug failure in 45 years,could happen I guess.
So you buy one new coil,start on one side of engine,and walk that coil from one cylinder to the next,every time you get a 300 misfire code. Put the OE back and move the new one. Consider you may have others on their way to going bad.
Make sure you have no vacuum leaks anywhere.
