What code(s) did you get? I would suspect a bad coil.

I thought it was the coils too the front too coils on the driver side aren't getting fire I put new coils in still no fire then the tested the plugs I thought we're bad and it turn out the we're good I switched the wiring as well still no luck

It was a circuit code

Switch the coils and plugs from the cylinders that are missing with the coils and plugs from known good cylinders. If the miss moves it is either the plug or the coil. If the miss does not move then it could be a fuel injector or wiring issue.

Can a bad fuel injector cause no spark
