Re: 97 aurora wont start

There are three things that are required for a car to run. Fuel, Compression and Spark.

Spark:
Take all 4 front plugs out and make sure that they are grounded. Now, have someone turn the car over and observe to make sure that there is consistent spark.

Fuel:
As I mentioned earlier, just because you changed the fuel pump does not guarantee that you are getting proper fuel pressure. You need to get a fuel pressure guage connected and measure the fuel pressure. After that if you still suspect a fuel problem then you need to check to make sure the injectors are firing.

Compression:
If you pass the other tests, then you should get a compression tester and check cylinder compression. All cylinders should be within 10% and should be around 165-190 psi for that car.
