Answer 1

Typically, when you have problems of this nature, it's a voltage issue, though not always. The starter could be bad. When it's cold, it may start fine, but as it warms up and transfers heat to the starter, the windings warm up and may, in some cases, lose contact until they cool down again. Some Chevy trucks are notorious for this, that why there is an after-market heat shield available. Also, some come from the factory with them. After you checked the battery, did you make sure the cables were tight? Run your hand down the ENTIRE length of the cables. If you find ANY "bumps" in the insulation, make sure it's not grease. If it isn't, replace the cable that's affected. You have a buildup of corrosion inside the insulation of the cable which is reducing the amperage to the starter. You may still have 12 volts, but you won't get the amperage necessary to drive the starter. Voltage doesn't mean a thing if you don't have the "push" behind the voltage. Good luck

I had the same problem with my '89 chevy celebrity wagon. It wasn't the starter, it was something involved with the starter and the temperature. A converter or something. When my car was hot (like when I'd just finished driving somewhere twenty minutes away) it wouldn't start, but if I waited until it cooled, it'd start up again. And the mechanics couldn't figure it out until the one time I got it to them while it was still hot. If the engine was shaking, that almost sounds like pistons misfiring, though. Definitely get it looked at.

Answer 3

Starter changed, tried the voltage regulator too ? How old is the battery? the walls in between the cells break down, and intermitantly short out showing a good battery now and then.

Answer 4

the timing belt might have slipped causing it to b out of time enough to strain the starter to turn over the engine. And finally the timing belt just snapped and this will shut u down

Answer 5

I have three things to tell you,first check your codes go to a parts store and they will give you a code book&key.. take the battery and check it ...check the water for sure if you have the vent ports.. take the alternator also if the alternator is bad, the injectors won't work neither !! your car can't run without fuel!! if no electrical current is going to the fuel pump the car dies.!!! AND CHECK ALL FUSSES EVEN THE INLINE hope I could help!!!

Answer 6

Sounds like crank sensor

Answer 7

check your ground wire to the engine block from the battery. The heat can cause resistance or a bad connection causing the car not to start or dye when it gets warm.

Answer 8

In spite of your battery testing good (did you do a load test on it?) I would say it's your battery, or the connections to the battery.

Answer 9

the alternater and have a full tune up from a dealer since know one can find a problem cause it happen to me

Answer 10

it sound like you have a timing problem, but it might be the starter
