We check the brain of car which is good. The coils are good, the fuel pump is good camshaft is good. We change the crank sensor, but the car just would not start.

Hi,

If you have an ignition spark, see if it starts for a couple of seconds using starting fluid. and then stalls. If it does, we know it's a fuel-related issue.

If there is no change, recheck the ignition spark.

Here is a link you may find helpful:

If you do have a good spark at the plugs and the starting fluid makes no difference, I need you to record it cranking and upload it for me to hear.

Also, I need to know which engine this has. Is it the 2.5L or the 3.5L?

Let me know what you find or if you have questions.

Take care,

Joe
