When I drive my vehicle around town doing stop and go type errands; my car won’t start after about the third stop. But, if I wait for 30 to 40 mins. it starts right up. Any ideas what could be happening? When I take it in for repair…the maint. folks say they can’t duplicate the problem while the vehicle is on their diagnostic machine…so there is nothing they can do.
I’m not sure is the starter solenoid is seperate from the starter on your vehicle or not and you didn’t state if this is a manual or automatic transmission. These things will determine what needs to be checked.
If voltage isn’t getting to the starter solenoid from the ignition switch it may be due to a safety switch, for the transmission, in between those points. The problem could also be with the starter solenoid or possibly the power to the ignition switch. I would first see if power is getting to the starter solenoid from the ignition switch when the trouble is happening. Then you will know what direction you need to go to find the problem. If the trouble is before the solenoid and you are able to work on things like this yourself it would be good to find out key points in the wiring to check where voltage is getting to when the trouble occurs and then check them with a test light probe.
There usually several areas in the starting circuit that can cause this. The ignition switch, some sort of safety switch, the starter solenoid contacts, or the wiring connections between these points.
Exactly what happens when you turn the key?
