1990 Buick LeSabre Questions & Answers
When to you when the cam is bad?
If it is out of time too much between the cam and crank, you stand a good chance of bending valves. A stuck lifter can cause a push rod to bend which will produce a noise and a cylinder to not work. Engine won't idle or rev up well when this happens.
Where is my fuel reset button
There is no such button. This may be related to the antitheft system The system is known for turning off the starter and/or injectors when it fails. Is there a light on the dash that says SECURITY? This is a common problem worth looking into. http://www.diy-gm-security.com/ g">
Where is my fuel shut off switch
There isn't one as far as I know.
If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure. Also check for a fuel injector pulse.
Your obd1, you should be able to check for applicable trouble codes, if there are any.
Missing terribly but runs. When put in gear it shuts off. What's wrong?
