Iac question

Can the IAC valve cause my Jeep to not start?


I have an 04 4.0 that will crank but no start...

open the throttle while your cranking it. If it still doesn't start, it's not the iac.

Make sure your CRANK POSITION SENSOR is attached. Driver side, plugs into the bellhousing about halfway up

Just cleaned the throttle body and IAC then tried what you recommended and still didn't start
