my car starts up fine i let it idle for like a min then i shut it off and try it again and it sounds like its going to start but it doesnt it just cranks after like 10-15 mins it will start again what could be causing this what should i look into i have fuel and spark, and it smells a lot like fuel thru intake mani

 

Faulty IAC valve
Clogged or Faulty PCV valve
Faulty Thermostat Sensor
Faulty Temperature Sensor
Fualty EGR valve or sensor

Any of the following going out will cause similar issues.

 

i have a new iac, deleted egr pcv valve is new also the temp sensor where is that located is it on the right side like in the bottom of the mani if it is that one did look real bad like it had a lot of junk stuck to it and i believe the thermostat sensor is the one on the other side that sits on a tube right
