Fuel or Electronic Issue?
I have a 02 Cadillac Deville. Car was running fine
until installed an amp. Battery died during
installation, charged battery & when went to leave
car acted likebit wasn't getting any gas. Gas hand
is out so went to get more gas just in case. Car
then didnt want to crank at all. Will crank if ether
into it but will die quickly. I think the issue has to
do with the installation of the amp but my friend
thinks it's the fuel pump. Idk alot about cars so we
replaced the fuel pump & it's still doing the same
thing as before. What is yalls opinion on what
could be wrong?
