Why does car start at times and other times won't do anything?
Have a 2000 Saturn SL1. Go out in the morning and it starts fine. Let it sit 20 minutes or so and it won't start. Won't crank over or make any sound. After sitting a couple hours it will start, then go through the same process. Drive it and turn it off it starts back up but if you wait a while it won't start. What could be the problem. The battery is fine.
Check your Engine Coolant temp sensor. It might be faulty. Remove it, Just take the air cleaner assembly off and it is located in the cylinder head under the air induction tube. Two wires are on the connector and the new part is made of brass. The original had a plastic tip, and if yours is plastic, I'd replace.
Its not the coolant temp sensor. The no crank condition is probably caused by a bad crank sensor.
Wasn't the coolant temp sensor. Advance Auto did a sensor test and said it was bad so I bought one and put it on - didn't help.
throw a crank sensor at it.
