replace the relay , when a relay sticks like that , a good test is to slap it with something like the handle of a screw driver , see if it un-sticks , its not a fix , just a test . cheers'

I've changed all the fuses, relays,and the starter on my 2002 Deville dhs and it still won't start.


It won't crank over ? Is there a SECURITY light lit on the instrument cluster .
In the under hood fuse / relay box is the start 1 relay , this relay is energized by the PCM - powertrain control module ! This is the relay that controls the starter ! If there is a anti-theft system problem the PCM will not energize the start 1 relay completing the circuit turning on the starter ! . If you knew how you could test right from the start 1 relay socket in the fuse box , rather that just replacing parts ! You can test with a DVOM -digital volt ohm meter or a test light ! Two of the four sockets have battery voltage , one should show ground an the last will show open , this is the control circuit from the PCM .

My radiator fans will not turn on. Where is the relay fan sensor located in a 1993 Cadillac Seville STS


They will only come on if the engine is over 225 degrees or the ac is on.The fans are controlled by the pcm. There are three fan relays located in the relay center under the hood on driver side. The puller fan (radiator side) is controlled by the PCM and relay B which is the first relay on the right side of the relay center counting from the front of the car (nearest driver side headlight).

Hey i have a cadillac sedan deville 1992 where is the fuel pump located


The fuel pump is located in the fuel tank. On these GM cars, the fuel tank must be dropped in order to change the pump. It is alos recomended that the fuel filter be changed at the same time which is on the frame of the vehicle, left side. the pump at autozone runs about $75 and don't forget the strainer for about $10. The filter runs about$10 also.
