2000 Isuzu Rodeo Question Car will not re-start

Have you checked to see weather there is no spark or no fuel when this happens?

Sorry to show my ignorance, I am not a "car" person. So, not sure what you mean by that question. I stop for gas or a rest, and my car will not re-start. Makes noise like it is trying to turn over, but does not. Always after 45 minutes or so, it re-starts.

Hi Ellen,

When engine could not start, it could be due to lack of ignition sparks or fuel is not being delivered. Test have to be carried out to determine what is missing to proceed with rectification.

The following links shows how to do the test and you should have a look at thsoe applicable topics to understand what needs to be done.

If it is ignition sparks related fault, it could be :
1. Engine Control Unit ( Engine Computer)
2. Sensors ( crank sensor, Engine coolant temperature sensor etc.

Does the Check Engine Light show while driving? If yes, go to your local Autozone parts outlet to perform a scan, ( they do it free ) retrieve the Diagnostic Trouble Code (DTC) and let us know the exact code.

Fuel related faults could be :
1. Wiring fault with the fuel delivery system such as loose or bad connections. When loose wire connections have voltage travelling through them, they overheats causing high resistance and this would prevent electrical component from working correctly.
2. Failling relays. They would provide bad contacts when heated.

Check the links and when problem happens, you need to check what is missing to enable us to assist in rectifying the problem.
