2005 Acura RSX ignition problem

Have you checked for a codes in the vehicle's computer or the fuses associated with the ignition system?

Check for power on one the three wires running to the coil. Check for the driver signal from the computer to the coil electrical connector. And ground. Let me know what you find. TY

Did you check the ignition coil relay and fuse in the fuse box behind the glove box? Fuse #31 w/a 15A fuse. These two provide power to the ignition coils when the ignition key in on. The black wire w/ a white strip is your power wire the solid black wire is your ground wire. Check for power and ground on these wire with the key on at each ignition coil connector. If these test check out good then load test the signal circuit with a light bulb to determine the circuit's integrity (ask me if your not sure how to do this) If this circuit is good at each ignition coil the vehicle's computer is faulty. Let me know how it goes, Ty
