1989 lesabre engine codes

There is no code 8 , codes start at 13

check the firing order for the HT leads as this indicative of crossed leads.

The relay should be in the engine compartment on the firewall under the windshield. There may be several relays in a cluster and they are not marked.
You would check the circuits the relay uses, or just replace it with a new relay. Some of the other relays can be switched for a test if they have the same type plug.

Should be about 4.
When you add 4, then park the car on a level surface, and wait about 15 minutes, and then check the level with the dipstick.
The low line and the full line are 1 quart apart.
Be blessed.

check your dash ground. the tail lights and dash lights run on the same circuit.

if the fuse is good, a ground is your most likely culprit.

disconnect the battery wait five minutes reconnect the battery let the computer reset this should put that check engine light out.

if i am thinking right this early.....u can with key on use a jumper wire ....on the dara port under dash jumpfrom A to B and count flashes of check eng.light...please check with autozone .com for specs......hope it helps

Please see my tip at http://www.fixya.com/cars/r5925550-dead_battery_troubleshooting . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

1989 buicks did not have a chip in keys. get someone to use a remote strter switch(which you can buy at a parts store). follow instructions. if it doesn't start; try there.

You need to determine why the fan is on (stuck relay, bad sensor etc.) If it remains on, the computer keeps engine controls in "cold-start" mode and will not operate properly. (re-check codes after the fan works right.)
