Ok. I have always used Sea foam like this to clean the engine every 10-15k miles or so.

I've done this a million times.

-Disconnect Brake Booster Line
-With engine idling, let stick the line in right above the can of sea foam, letting it suck it up and playing with the throttle in order to keep the engine from stalling
-After I've gotten about 1/3 through the bottle, I let it suck up so much that it stalls out in order to get liquid sea foam in the cylinders to really clean the gack off.
-Wait about 3 minutes...then start the car up and make a huge toxic cloud of death
-Let the car sip a tiny bit more sea foam just to blast any remaining crap out

I've never had a problem.

Yet this evening, after letting the car stall and waiting 3 minutes, it wouldn't start back up. I figured maybe it was too wet in there, so I pulled the spark plugs and let everything air out for about 10 min. Reinstalled spark plugs, disconnected fuel pump, cranked the engine a couple times. Then reinstalled fuel pump fuse, tried to start. Still just cranking away.

Decided to pull the plugs and let it air again for about 2 hours. Came back after 2 hours and tried to start again.

....nothing.

What happened? Could I have hydro(sea foam)locked the motor? What can I do?

I pulled the plugs again and I'm going to try again tomorrow morning.

 

Take a good look at the plugs, you may also want to check out the fuel injectors.

 

I forgot to mention that I also swapped the plugs out for some other ones and it still will not start.

And what about the fuel injectors? How could they have been messed up by putting sea foam through the intake manifold?

 

Sounds to me if the car is getting fuel and spark it should start because I have never seen sea foam hurt anything and at the rate you were putting it in it should not have done that.

You need to check your fuses, and make sure it is getting fuel and spark then go from there

The injectors are the only other necessary component between the plenum and the head, so unless you think the Seafoam disintegrated your valves, it wouldn't hurt to check them out. I've seen stranger things happen.

 

if you used it correctly this wouldn't have happened.

 

what's correctly.

I've done this at least 50 times.

 

it's very possible that you sea foamed correctly, but are now having a completely unrelated problem at a very coicidental time. try checking the usual culprits for a motor that cranks, but doesn't start (i'd start at the ignition switch).

 

yeah thanks. I'm checking out the distributor as we speak.

 

When you try to start the car and the engine turns over, then it isn't hydro-locked. Hydro-locking would prevent the piston from moving once it trys to compresses enough liquid instead of a gas. The piston could move if a rod gets bent in the process of course, but you would hear a clack, clack, clack, clack. You could try to shoot some starter fluid into the throttle body to give the charge a chance to ignite. If not, go back to the basics and check for fuel and spark.

well when i was reading the instructions. it says "pour SLOWLY into hose while the car is running"

sorry, but u have been the last 50 wrong

 

yeah you hydro locked it. You are suppose to hold the idle at 2k and take in little sips at a time instead of letting it suck all the sea foam.
