When trying to start my 98 civic it clicks I have swapped out the ignition switch to bypass the alarm and still nothing , I have also installed brand new starter and battery. Most of the time when I try to start it nothing happened just clicking from my main relays and I hear a small buzzing coming from around my ecu area and then at randon it will start,I checked all my plugs are good under the hood and I installed 2 new engine ground wires
This really stumps me. I left my car light on at work one day and it killed the battery this is how it all started
But before that it started like nothing

. Check all under hood and under dash fuses with a test light or multimeter--especially focus on the ACG (ALT) (S) fuse in the under dash fuse box.

. Clean the main ECM ground, located on the thermostat housing.

. Perform the K-Test on the ECM.

How do I do the k test?

Use the search function.

I'm pretty sure the ecm is fine because when I push start the car it runs perfectly fine
