97 dodge grand caravan cranks but doesn’t start in the mornings. Starts and runs in the afternoon. I’m from California, low temperatures where I’m at dont drop below 60 at the moment. Highs reach 100 at the moment. I am leaning towards something to do with the temperature. Is there a sensor, connection, ect, that can be affected with the heat that might cause this? Or what do you guys think?
Battery is strong. Fuel pressure is fine.

When it does not start, does it just crank, or does it seem like it wants to start and then dies?
Could be a number of things. When is is not starting, you need to make sure you have spark, air and fuel. Beyond that a scanner with live data will help. Sometimes things like a bad coolant temp sensor can cause the IAC to choke off the air. it would be good to note the data values for sensors when it will not start and then when it will, that may lead you to a solution.
No. It doesn’t start at all. Just cranks. But when the temperature goes up, in the afternoon, it’ll start in the first attempt.
What data should I look for in the live data? I have access to a scanner with live data.
