You need to put more gas in it
To reset the service CCR light on a 1991 Eldorado, disconnect the battery for 10 minutes. Reconnect it and start the car.
I have a 2000 Windstar and it does this at times but it is normally when I start it and go to quickly not letting it idle down. Also mine has 322,000 with original transmission and motor and it has done it for several years.
You need a new battery!
2007 trailblazer does not start, sometimes it does and sometimes it does not.
The starter drive, also sometimes called the bendix, needs to be replaced.
Start with no starter??That car isn't going anywhere unless you change the starter or tow it.
If it jerks then dies, it could be the lockup torque converter is stuck and whenever you put it in drive it's "direct drive" without the advantage of a torque converter. That only applies if the engine is running well and there are no other symptoms. As always, check for a computer diagnostic code using a code scanner.
