Car won't start after TB cleaning: 01 Accord I4

[kn0x47]

long version:
my gf's cg has idled low for a long time so i decided to clean the throttle body. I ended up spraying cleaning into the hole for the IACV and when i tried to start it later on the car came on, rpms went up to about 2500 for a sec then they dropped and the car completely shut off and wouldnt come back on.

I assumed there was cleaner up in the IACV so i completely removed the throttle body and IACV to clean them, replaced the gaskets (found out the vacuum hose to the IACV was cracked so I replaced that too, which i assume caused the idling issue). When i put everything back together I forgot to plug in the TP sensor and accidentally plugged the connector for the TP into the map sensor.

sooo... after getting a check engine light for that, smelling burnt gas and the car not staying on I figured out what I did wrong and fixed it. After clearing the check engine light and having it back together correctly I turned it on, the rpms went up to 2500 for a sec then the car shut off again and wouldnt come back on. I've figured out that the fuel pump isnt coming on everytime I turn the key. If i unplug the battery, wait a bit, then plug it back in the car comes on, rpms go up to 2500 then shuts off. Every time after that I don't hear the fuel pump come on unless i disconnect/reconnect the battery again.


Short version: after trying to clean the throttle body and getting cleaner into the IACV the rpms jump to 2500 then the car shuts off and won't come back on. I've noticed I cant here the fuel pump come on unless i disconnect then reconnect the battery and whenever I do that the car comes on, rpms up to 2500 then it shuts off



fuel pump fuse is fine, there's no check engine code and I can hear the main relay coming on

HELP!!! I have 2 weeks to fix this and several other things on her car before she gets back from China

Is the fuel pump still trying to pump after it shuts off? Are the injectors getting a pulse? Are all vaccuum hoses hooked back up correctly?
Do you own a Haynes manual? If not get one because you may have drowned the engine and may need to pull the intake manifold and dump all the cleaner out. In essence, you may have flooded it and it and the cleaner needs to evaporate.

Vacuum leak?

Does the engine sound like its turning over more quickly than it used to? Ive seen TB cleaner "fuel wash" the cylinders. This would also explain the gas smell. Take out the spark plugs, turn over the engine a few times with the key, and then put half a cap of oil in each cylinder. Throw the plugs back in and see if it will start. Its normal for it to smoke for a few seconds after this due to the oil in the cylinders.
