2002 Toyota MR2 Spyder Base 4 Cyl 1.80L


why engine won't start?

Early in the morning on the way to work I stopped at 711 store for coffee. Returned in 5 minutes to find out the engine won't start. no clicking no noise at all when the key turned to ignition. I have a brand new battery. after about a dozen attempt, it started as normal. I went to work and parked the car and returned about 2 hours later to see if it starts. It did not. This time I tried many more times and nothing happened. dead silence each key turn. I told everyone at work that I needed a push start when quitting time comes. However, when quitting time came after about 6 hours later, It started at first attempt with no problem. Upon returning to home I tried to start every half an hour and it started just fine at each try. What should I do?

First, check the battery and starter cables for their tightness or free of corrosion and physical damaged.
See this Starting system simplified diagram. Have a help from an assistant to crank the engine, use a 12 volt light tester ( or a Digital Voltmeter ), apply it to the starter control circuit.
If there isn't no light, then the ignition switch is the culprit.
If there is light and the starter isn't crank, then the starter is the culprit. Have the starter to bench test for free at the local auto parts stores.
