Trouble Code - AutoZone

www.autozone.com/.../Buick.../_/P-0996b43f8036fc4e

AutoZone... power circuit is open (check ENG EMISS fuse). Purge solenoid is damaged, or the PCM has failed. TSB 71-65-66 contains a repair procedure for this code ..

Not sure you mean the lighter or the fuse for the lighter.
The lighter should be close to the ashtray.

The fuse should be behind the ashtray under the dash. It may be a fuse or a fusible link.

Hope this helps.

Change the fuel relay

20 is a lot and is probably right. Does it blow out when you use defrost or just heat? The reason I ask is because the air conditioner comes on when it is on defrost.

This has happened with GM vehicles since back in the early 90's. that part is called the dash pad and there are companys out there that make covers or replacement pads. Search google for your " Dash pad 2003 Buick LeSabre"

Try a crank sensor yet?

could be weak fuel pump, Egr issue, Throttle position sensor, plugged fuel filter.

Both & more compression timing, gotta check for spark easiest then ck fuel get guage. good luck get more info check back in

if there is an access plate you can remove then yes. but generally you have to drop the tank to get to it

Hi there,

I had the same problem with my 89 Buick Le sabre. It turned out that I had to replace the computer. It was giving the wrong signals and cutting off the fuel. My engine light came on each time it happened. Since the computer was changed it has run like a charm. It cost about $500.
Also when they ran the tests for the eng light data the computer was giving the wrong info and so many of the wrong parts were first replaced.
