New guy with 99 Camry LE starting probs

[zukyota]

My wife has a 99 Camry LE with 155,000 miles. The car runs great & I keep up all the maintanence on it. Havn't had any probs till now. When the car has been driven for a little while & parked for say 30 minutes, it will not start. If you let it sit for maybe 10 - 20 minutes after the first try it will start up. I'm really confused on this one. She say's it seems to do it after running the air. Any suggestions ?

how your coolant levels?

could be the ect, not getting a correct reading of the engine temp, also check for any vacuum leaks and that the iac is clear

Coolant levels are fine. I hate to sound ignorant but what is the ect & iac? Thanks for the quick response.

Sounds like a fuel issue. Start by trying a quality fuel injector cleaner like seafoam. Could also be a igniter or ignition coil.

ECT is the engine coolant temperature sensor.

IAC is the idle air control valve.
