C240 02

If you could get the dtc that is stored when the engine light came on it would give us all more information to be able to make n educated guess since e are diagnosing at long distance. The members here have a lot of knowledge stored in their minds but we can't use it if we have no input to allow us to use that knowledge. Its like asking some I have a flat tire and expecting us to tell you which position the flat one is in. So give us something to work with and we will attempt to help.

Its was a crank sensor...all is well.

Thanks Jim

Have a great Weekend!

Have the shop check the ignition module if it has one. It should be in or around the distributor. These like to go bad.

What make & model? Does it smoke when you first crank it?

DTC stands for diagnostic trouble code and to pull them you need to have it plugged into a OBD2 scanner. Most auto part stores will plug in and read the codes and give them to you. where they come from is the onboard computer monitors a multitude of sensors in the vehicle and if they give readings outside of the allowable range then it will store a code in the computer which allows a technician to progress through a diagnostic tree of test and will guide you to the faulty system. It sounds extremely complex but if there are more than one code stored then a good tech can usually determine the problem from experience and knowledge of how all of the systems talk to each other.

I am going to bet that either you are out of gas or the crankshaft position sensor is bad.

Mechanic A says it could be the ignition module. Mechanic B says it could be out of gasoline. Mechanic Bob C says that it could be time to drink my self stupid.
