Will This car start and run because mine will not. and it does the same thing If you have found out anything please respond and let me know thank you
I forgot to tell you after you connect the battery with the key in start position try to start the car after you reconnect the battery
If the security light is flashing you need to change the ignition switch it self. It is likely worn out.
Cycle the ignition on/off/on/off/on and count the flashes of the check engine light. A pattern of two flashes, pause, two flashes would be a code 22.
I have a 90 cutlass supreme. Mine has been going goofy for some time now. If it blacks out, flashes off and on, or shows different readings on fuel gauge, odometer or speedometer then you have problem. I took it out and looked for loose plug wires(1 plug) or cicuits. Found none. Needs replaced. Can sometimes be found on Ebay for cheap price. If so make sure it right one!!!
To program the security warning light in a 1998 Buick Regal LS, you typically need to use the vehicle's ignition system. Start by turning the ignition to the "ON" position without starting the engine. Then, press and hold the "lock" button on the key fob for about 15 seconds until the security light flashes, indicating programming was successful. If your vehicle has specific security features or a factory alarm, consult the owner's manual for detailed instructions.
You replace the ignition cylinder and then turn the ignition (with key) to on position. All dash lights will light up in the on position. After a few seconds only the security light will flash. Leave the ignition on for 10 minutes while the security light flashes. At the end of the 10 minutes the security light will go out. This will be the first cycle of reseting the E.C.M. to read the new cylinder and ignition system replacement. At this point you do this process two more times. This will take proximately 30 minutes. At the end of all three cycles the car should come on. If you want someone to walk you through it E mail me at archuleta67@gmail.com.
Turn the ignition key on,off,on,off then on and count the the flashes of the check engine symbol .It flashes the first number then there is a short pause then it flashes the second number. Example 24 ( two flashes and a pause then four flashes). Look up this number in Chilton's/Haynes or the shop manual for the vehicle
Trouble code P0302 means:Cylinder 2 misfire detected
To read trouble codes in a 1991 Oldsmobile Ninety-Eight, you need to locate the diagnostic connector, typically found under the dashboard near the steering column. Use a jumper wire to connect terminals A and B of the ALDL (Assembly Line Diagnostic Link) connector. Then, turn the ignition key to the "On" position without starting the engine; the check engine light will blink the trouble codes in a series of flashes. Count the flashes to interpret the codes, which can be referenced in a repair manual for further diagnosis.
