My 2000 cadillac sts won't do nothing but crank up


have the fuel pressure checked with a gage as if its the fuel pump not functioning properly can cause this problem. also if you have anti-theft on the car it may have activated for some reason and needs to be reset.

1998 sts wont start unless u hit the gas then it runs rough ..u put it in drive it wont run over 2000 rpms then it dies


Is the gas tank above 1/2 tank now?

A worn / aged fuel pump will fail when it's hot and the fuel level is low (example: below 1/4)

Park your car in a cool area.

Start the car when it's cold outside,

Fuel pump relay keeps blowing on my 1996 Cadillac STS, why?


Sounds like the fuel pump is drawing too much amperage. If so, it will burn up the relay.
