WHEN I START THE CAR SOMETIMES IT WOULD START BUT JUST SHAKE AND CUT BACK OFF, OTHER TIMES IT WOULDN'T START AT ALL....IT DOESN'T MAKE ANY CLICKING NOSE OR ANY TYPE OF NOISE AT ALL, IT JUST DOESN'T START. THE RADIO, AND LIGHTS WORK. THERE'S A NEW BATTERY, A NEW ALTERNATOR, AND A NEW STARTER INSTALLED. WHEN IT STARTS AND SHUTS BACK OFF, I TRY TO ACCELERATE ON THE GAS TO KEEP IT RUNNING BUT IT STILL JUST DIES BACK OUT. I HAVE HAD IT CHECKED OUT AND EVERYONE SAYS NOTHING IS WRONG WITH IT BECAUSE IT DOESN'T HAPPEN WHILE IT'S IN THE SHOP.
