Heat soak to starter solenoid. Replace solenoid and insure all heat shields are in place.

My car has plenty of battery to start car but car will not turn over.we traveled about10 miles and car would not start.let car sit for10 minutes cr started .new battery even though we had all lights.


When you say travelled 10 miles then would not start, do you mean it would not crank at all, or cranks but doesn't start? If no crank, could be faulty starter motor/solenoid getting heat soaked. If it cranks but won't fire up, more likely bad ignition module, coil, crank or cam sensor. They get hot and can fail just when hot.

Hot starting problems are usually fuel related. When a hot engine is shut off, the temperature of the engine and everything on it continues to rise for awhile as the engine undergoes a period of "heat soak." This can cause fuel to boil inside the carburetor bowl, fuel lines and fuel filter. When you attempt to restart the engine, "vapor lock" obstructs the flow of fuel and the engine doesn't want to start.
This is much less of a problem on fuel injected engines because the fuel is usually under much higher pressure inside the injectors and fuel line. Even so, a fuel line routed near an exhaust manifold or a fuel rail that's exposed to a lot of heat may still suffer the same kind of problems.
Heat soak problems such as these can sometimes be cured by wrapping insulation around affected fuel lines, and/or installing an insulating spacer or heat shield under the carburetor.

A Seasonal Problem Hard hard starting tends to be a seasonal problem, but may be worse in the early months of spring when refiners are switching fuel blends. Gasoline refiners produce fuel with a slightly lower volatility rating (called "Reed vapor pressure") during hot summer months because lower volatility fuel is less likely to boil and cause hot starting problems. During the winter, they switch to a higher volatility fuel because it makes cold starting easier. But if you still have "winter" grade fuel in your tank when warm spring weather arrives, you may experience some hot starting problems. The problem will go away, however, as soon as the refiners in your area switch to their summer grade fuel.
Other Causes Hot starting problems can also be caused by cooling problems that allow your engine to run too hot (the pistons swell up and may scuff the cylinder walls), or excessive resistance in the starter motor that causes the engine to crank slowly. A starter "amp draw" test can be used to check the condition of your starter. Also, many starters have small "heat shields" to protect them from heat radiating from nearby exhaust pipes or manifolds. If the shield is missing, the starter may get too hot and bind up.

Crank sensor


let vechicle sit for a while could be flooded fuel injectors leaking.when fuel injectors become dirty clogged they will leak when you turn off the engine.see if engine restart if its sits while.if car still dont crank check for spark.no spark could be faulty ignition module or crankshaft position sensor and camshaft sensor.have vechicle code scan first before buying new parts.meant to say bad engine coolant temperature sensor will cause no start hot engine and clogged air filter.

My car shuts off while driving. I'm not low on gas, or oil. It was not over heating. If i let the car sit for about 30 minutes, it will start back up again and drive for about 30 minutes before it


The engine in this car is electronically controlled and a problem like this would leave a fault code in the memory of the computer control module, to retrieve this code or codes you need the system scanned with a special tool, this is called an "OBD 2" fault code test.

My hummer has hard start when it's turned off for ashort period,


A scan tool should be able to read the temp pids at operating temperature to see if they are "off" enough to cause problems . Check for fuel lines to close to heat sources as boiling of the fuel causing vapor lock may be happening after heat soaking .
