Hello

I recently cleaned out my throttle body and intake along with the IAC sensor to fix a rough idle and stalling. After plugging everything back in, the car will not start. It cranks over, takes in fuel and there is a spark but no start up. It started up before I cleaned everything however. What can I do to fix the problem?
Thanks in advance, Mike

If you cleaned the throttle body by spraying cleaner into the barrel on vehicle, the engine is flooded and would require some additional cranking to get it started.

Try with throttle fully opened for a few seconds.

How much cranking would I need to do? I continuously cranked it for about 10 seconds

When you say "throttle fully opened" should I press down on the gas pedal to open up throttle plate?

The valve and ignition timing could be off-also what is the fuel pressure-you probably touch something you shouldn't have backtrack everything that you've touched-

How can I check the valve and ignition timing?
The fuel pressure seems fine after an inspection, I smell A lot of fuel in the hood after cranking the engine trying to start it.

I just disconnected three plugs and covered them with a towel so that any cleaner will not get into them.
I also removed and clean the idle sensor pulley thats connected to the throttle body itself.
Replaced the gasket between the gasket and the intake as well.
Plugged back all three plugs/sensors.

Ill try adding starter fluid into my cold air intake and see if the car will start from there.

I tried putting it into CLEAR FLOOD MODE but after a few minutes still no luck. So I removed the fuel pump fuse to help the engine clear out and that worked! I guess I sprayed too much clearing into the engine. Thanks for the help
