Honda not Starting after seafoam treatment
Okay I have a 2004 Civic DX Coupe has 190,000 miles on it.
So I just got this car and was trying to just do some preventive maintenance to make sure everything was operating at the best it could. So I decided to do seafoam. Did the can in the tank, 4 OZ in the oil, then was doing the spray into the intake. When I was about half way done with the bottle it kinda shook and made my hand slip off the throttle and it died. So I went to start it to keep the treatment going and it now will not start.
It turns over but doesn't even try to start. So far I have waited two days to make sure the seafoam had evaporated. I checked the spark plugs today and decided to change them. Still no luck. There is no check engine light that is on. I got some starting fluid and still no start and not even close to starting.
I'm thinking ignition coils but there is no check engine light. I'm planning on checking the cylinder compression as well. Does anyone have any other ideas or has had this happen?

Re: Honda not Starting after seafoam treatment
Cylinders may be flooded? Try cranking the engine with the gas pedal fully depressed (WOT). This will disable the injectors and allow maximum airflow.

Pull the spark plugs and crank it, see if anything come comes out, if they reek of seafoam leave the plugs out overnight and try again

Probably flooded it, plugs got wet and now won't fire.
Might also have a pool of liquid down in the bottom of the intake manifold. You might want to extract that out of there before it decides to cause more problems

You should not be buying and changing parts. You will just create more and separate problems. Verify you have fuel pressure and the injectors pulse, verify spark, don't start buying parts.

I would recommend rechecking with a plug grounded to a good ground that you reeeeally have no spark, and then waiting from some of the smarter minds here why that might be. I can't imagine four coils could possibly fail at the same time, and usually those are not returnable, so I'd hate to see you waste money on something you don't need.

I verified there is no spark. I took each plug and put it up against the block in order to ground it and there was no spark. I'll check out that link.

Are you sure the ECU is even on? Hook a code reader up to it? Check engine light starts on, but turns off?
Next I would check all the harness ground connectors on the engine and frame.. by check I mean unbolt, clean, apply dab dielectric grease and rebolt.
Dont ignore fact previous owner might have put some aftermarket thingajob on it thinking no one is gonna steal it now and forgot to tell you about it....

I'm thinking ignition coils but
I will have the Coils tomorrow and will replace them all
Test, don't guess.

Depends on which fuse it was. Some cover far more than just what is listed on the label. .
Which position number in which fuse box?
WHY did it blow?

According to the manual i have in front of me:
Fuse 17 is labeled fuel pump.
Provides power to SRS, PCM terminal E9, and main relay #2
Soooo yea if the PCM is missing one of its power sources I can see it not letting anything work including everything for ignition (spark) output.
But what caused the fuse to blow?

i would guess that all the violent shaking and rumbling caused the wiring to bounce around quite a bit, probably an intermittent loss of connection or intermittent short. just a wild guess though
after my last sea foam incident, i kinda outgrew the stuff. this: https://www.civicforums.com/forums/2...ml#post4743074
thank you for coming back and reporting the fix (:
