97 deville theft system problem
Does it turn over? Does it have fuel/spark/compression?
replaced battery in 1991 cad deville and reprogramed computer as car manual said. now car will turn over but not start
check for sticky brake calibers
go buy some fuel. if it doesnt start check fuel pump.
sounds like a weak battery or poor connection
Cadillac did not produce a DEVILLE convertible in 1983. ELDORAO yes. If it is a 1983 DEVILLE convertible, its custom made. To start remove the lower rear seat cushion and inside trim. Sorry I cant help further not knowing its customizing technique.
Check your battery, starter moter, fuel in the tank, fuel pump...etc.
Start by disconnecting the battery.
Answer Bad fuel pump what do you mean won't start? does the engine cranks or what does it do when you turn your key? answer that and i might be able to help you.
there is no fuse for the headlights. Could be many reasons. Start with the fusible links down by the starter.
chupame el peñoño then ill answer the Q
start with checking thermostat
Majority of the time the problem is in the ignition key chip or ignition lock cylinder
It would depend on the condition of the battery and if the battery charger has a jump start mode.
First you need to give a little more info.Will engine crank or not, is engine getting fuel.
Fins were widely popular in the 1950s and early 1960s. For a prime example, look at the 1959 Cadillac DeVille.
Turn your key to run position or start your car hold the off and warmer buttons for 3 seconds and your codes will be displayed below your speed, they come pretty fast so if you cant keep up just press off again and they will be displayed again turn your key to off to exit
If it does not blow at all then that is a problem, but if it is when you first start it, the Caddy will not blow air on you until it is the selected temp.
sounds like bad head or gasket do compression test on cylinders
If the "check engine" has or is illuminated start with having the code(s) read. The code(s) may help you locate the problem.
From the climate control system, which acts as the diagnostic computer. Press and hold the off and warm buttons together. You will see the system 888 then 7.0 then the active codes will start to show. Write them down. You can google amost any code you find. To clear all the codes, press and hold the off and high buttons together.
disconnect the battery off for 5sec it's like a hard reset then connect and try then good luck
put door key in passenger door turn it to the left and hold it this should de-activate the theft system
