We need fuel, spark, and compression in order to start the engine. Here is a guide that will help:

When you say the pump kicks on and you have fire, I assume you have spark? If so, how are you confirming you have spark? If you have spark at the plugs then use starter fluid in the intake to see if it starts briefly.

If you have spark then we can assume it is not a theft issue but is the security light turning off?

Let's start here and go from there. Thanks

Hi,

I want you to try something and see what happens. Try starting it with starting fluid. If it starts and then stalls, we know it is a fuel related issue. If it does nothing, we need to recheck ignition spark.

You indicated the pump turns on, have you confirmed pressure is within the manufacturer's specs? Also, let me know if you have checked for an injector pulse.

Is it possible for you to record the engine cranking and upload it for me to hear?

Take a look through this link as well and see if anything is helpful:

Let me know. Also, let me know if this happened all at once.

Joe
