Monte Carlo
With a key...
people start buying Chevy cars

what does it do
check fuel pump, check coil pack.
First check crank sensor again. A terminal gets bent sometimes during installation. Look at it good with a light. Then, VATS module, under dash, left of steering collumn, velcrowed in.
my 96 Monte Carlo did that and it ended up being the chip on the key went bad and it was the switch shutting the fuel pump down for security reasons. call a locksmith....i did

You call the dealer or a locksmith and get a new key.
