I have a 98 olds intrigue and I have a real problem my master cylinder connector is broken needs to be replaced and I dont know if that is making chk engine light come cpu is not scanning only error


I doubt the master cylinder connector is causing the problem of not being able to scan the ECM.

You didn't say which connector is broken but I doubt it has put the engine check light on unless it is affecting the emissions. By convention the engine check light should only illuminate when a fault is detected that affects the emissions.

I speculate the reason it won't scan is either the equipment used was faulty or inappropriate or you are possibly facing a problem with the ECM.
It is possible a diagnostician, rather than a guy driving a scanner, could provide the answer for you.

Engine will turn but will not start


Hi there:
You will have to pinpoint what the engine is missing...
- Spark
- Fuel
- Compression

All three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the engine to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should.

Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition. Be extremely careful when doing these tests.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

You need to find out the fault code that is stored that is causing the check engine light, the whole thing may be related to one failed part like the temperature sensor or the wiring to it.

Your best bet would be to have the vehicle checked for DTC'S - diagnostic trouble codes ! May not be a sensor problem , could be a wiring issue . Most auto part stores will do this for free , and if it is a sensor they can show you where it lives an how to change it !
