1996 cadillac sevile wont accelerate and cuts off

Chances are your Imobilizer is keeping your car from starting, try using a different key. Is the car cranking and then shutting off a second later? Any lights flashing on the dash? Highly unlikely that a brake fluid leak would prevent your car from starting. The only way thAt would be possible is if the fluid leaked onto a module and ate away at your board.

Some of them has out side,most is inside.Big job,big money.

why dose my 1997 cadilac sevill always over heat

If the fuse is ok, then replace the blower motor and the blower motor resistor pack. This was the only cause I have ever seen on those cars.

Test the electrical circuit . Testing Electric Fuel Pump Problems with Voltage Drop Test

this trouble code means your system is running to lean on bank 2, Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 2 is generally the side of the engine that doesn't have cylinder #1. You will more than likely not notice any drivability problems, although there may be symptoms such as a lack of power, detonation (spark knock), and/or a hesitation/surge on acceleration

normally when you switch on the a/c the engine revs increase to compensate, the module that controls this in your case could be faulty & needs to be replaced....hope this helps....cheers

the window in my 96 sevile wont roll up any more ( Front driver side) why?

CHECK FUSE AND RELAY FIRST IF THEY ARE GOOD.SOUND LIKE FUEL PUMP IS FAULTY.

Put a diesel additive in and see if that helps.
