Chevrolet: Chevy Celebrity, chevy celebrity, head gasket

Question
A few days ago my 1990 Chevy Celebrity overheated and stalled. Now it won't start. Someone told me that there is a sensor that keeps the car from running so you don't damage the engine. If so, how hard is it to replace and get my car up and running again?


Thanx,
Stacey

Answer
help. thanks  keithhi stacy, there is no sensor that shuts the engine down to prevent damage, my guess would be a head gasket or a warped head. do a compression test on the engine to determine if thats the problem.if thats ok, check for fuel and spark,if you need more help let me know.   hope this is of some
