#2 clyinder not firing in a 02 eldorado with 19000
There are several possibilities.
Based on the year (2002) and low miles (19,000) it probably has the original Plugs, Wires and Coil. Rubber insulation on Wires does dry rot over a period of time. Spark Plugs should be changed about every 3 to 4 years regardless of miles. Wires should be replaced every other Spark Plug change. Translated you should be on you 3rd set of Spark Plugs and 2nd set of wires.
When working in the engine compartment and with the electrical system remember: ther is 40,000 to 75,000 volts present. Bad Wires could mean an electrical shock!
You can cheaply purchase Ignition (Spark Plug/Wire/Coil) Test Kits at most auto parts stores or even at Harbor Freight.
1) Remove the #2 Wire connection to the #2 Coil position.
2) Insert the tester into the #2 Coil position. Clipping the other end onto the engine block or onto a good ground.
3) Start the Engine.
4) You will be looking for a good strong (blue) and rhythmic spark. If it is not strong (yellow or orange) nor rhythmic, the Coil is malfunctioning and should be replaced.
5) If it is a good rhythmic spark, Turn OFF the Engine.
6) Disconnect the Tester and reconnect the #2 Wire to the #2 Coil position.
7) Disconnect the #2 Wire from the #2 Spark Plug.
8) Connect the Tester into the end of the #2 Wire. Clipping the other end to the engine block or a good ground.
9) Start the Engine.
10) Again you are looking for a strong (blue) and rhythmic spark. If is not strong (yellow or orage) and rhythmic, the Wire is bad and should be replaced. Wires should always be changed as a Set is the standard rule.
11) If it is a good rhythmic spark, Turn OFF the Engine.
12) Remove the #2 Spark Plug out of the engine.
13) Check the Igntion end of the Plug for carbon, dirt, or being fouled. Check the Gap.
14) Insert the #2 Spark Plug back into the #2 Wire.
15) Using the Spark Plug Tester. Connect the Tester to the #2 and clip the other end to the engine block or a good ground.
16) Start the Engine.
17) Once again you should be checking for a strong (blue) and rhythmic spark. If it is not strong (yellow or orange) nor rhythmic, the Spark Plug could be malfunctioning.
18) Clean the #2 Spark Plug.
19) Regap the #2 Spark Plug.
20) Retest the Spark Plug.
21) If there is now a strong (blue) and rhythmic spark, then the #2 Spark Plug is now good.
22) If there is not a strong (yellow or orange) nor rhythmic spark the #2 Spark Plug is malfunctioning and needs to be replaced. Again the standard rule is to replace the Spark Plugs as a set.
The several other possibilities relate to sensors. However without additional error codes or the check engine light on, we will assume that the problem can be solved with the solution above.

2002catillac devil find battery
The battery is located under the rear seat. You have to remove the rear seat bottom to get to it. remove the 3 bolts just under the front edge of the seat and lift the seat bottom out of the way. good luck
WHEN I TURN UP THE
Either the flap inside the venting behind dash panel is stuck in one direction, or the actuator that moves it is faulty. You will have to remove bottom part of dash/console to access venting. A faulty heater core will also cause NO heat
Air flow thru defrost and floor vents,but not dash
It sounds like one of the flaps that control air flow is stuck, you have a vacuum line leaking or disconnected, or the vacuum actuator is defective. Look up under the dash to see if anything is out of the ordinary. Look for any hoses hanging down that might have gotten snagged by someone's foot and gotten pulled loose. Hope this helped you and good luck.
2002 cadillac eldorado horn blows and lights flash
. Seems like the system is not being diarmed. If it wont disarm with remote or by the door klock key, try this. Don't use the power door lock button to lock the car. Lock it MANUALLY till its repaired
Impact sensors
should have one inside the engine bay, next the your intake manifold on the passenger side. The other should be underneath before the catalytic converter.
hope this helps :)
How do I fix codes 51 and 52 on a 1984 Eldorado Biarritz?
Those are mem-cal codes, unless you changed the ECM the PROM (a separate part inside the ECM) has gone bad or the ECM itself went bad, if you just replaced your ECM with a used one you need to swap PROMS just remove the 2 screws and remove the plate then the PROMS. If this doesn't workYour best avenue is to remove the ECM then go to a parts store that sell Standard Motor Products they have an R+R program and will repair your ECM and PROM and send it back. I hope this helps. Take Care.
