2003 accord lx 2.4 ignition issue
 

hello guys, im working on a car for a friend and it has a weird issue.

its only running on 2 cylinders.

i replaced a coil pack thinking that was the problem but its not. apparently the left 2 cylinders arent getting power to the coil packs.ive checked fuses and relays, and tomorrow i am going to check at the ECU whether there is power at the wires there.

has anyone had an issue like this before?
if there isnt power at the ecu for those cylinders, im thinking it might be his ecu.

The cylinder numbers are 1 thru 4 with 1 being on the end of the engine where the drive belt is. Please let us know which cylinders (left for someone looking at the engine while infront of the car would be 1 and 2, while on the mechanics left would be 3 and 4.

Have you verified spark or no spark on the miss firing cylinders. What are the check engine codes?

Which two coils are not getting power? Almost liike Turtlehead said, "left for someone looking at the engine while in front of the car would be the passenger side, while on the mechanics left would be the driver's side."
