If there's no coil tower spark then nothing is getting to the coil packs which points to the ignition module or something talking to the ignition module.

I'll have to go look up how to test the ignition module. They never went bad on the earlier generations but quit a few people have had them fail on the third gen s cars. We'll just have to work our way backwards now to find the issue.

Ignition modules for these cars are pricey due to their age. Don't run out and buy one. Shot gunning parts at this level gets expensive very quickly.

Still don't get the no fuel connection. Maybe they are not connected. Do you own an oscilloscope?

I do not own a oscilloscope. I was wondering if the PCM maybe went bad? I don’t want to shot gun anything because that is pricey also. I have taken the pcm off and checked the connection/prongs and things look good. Honestly it looks brand new under there.

OK, so NO codes, pending or current.
Have you confirmed voltage AT the coil pack? As in, is 12VDC making it to the CP?
If so,

confirm PCM is grounding thru relay, I think that's what derf is getting at.
Whitey is a 2001!! I can confirm Voltages and resistance values if necessary.

Hey Dude,
im a little new using a multimeter- what is the easiest way to check for this?

Dude Dec 18, 2022 04:31 PM

We gotta find a connector pic w/connections, my daughter just took Whitey cause I need to look over her Accord! She literally just took it.

Does this help?

Dude Dec 18, 2022 04:32 PM

Ow, Shayt.

Happy you are alive. What got broken and I don't mean the car?

derf Dec 19, 2022 07:10 AM

Yeah I'm assuming nothing is getting to the coil packs because nothing is coming from the ICM. I don't suspect the coil packs not being grounded as they are supposedly grounded through the bolts that hold them in and that's not going to change overnight.

I've been working like a dog but I will look today during a break at what the voltages should be at the ICM connectors.
