Whats the battery voltage?

What does the theft light do with the key out of the ignition?
What does the theft light do while holding the key in the start position?
Do al lthe dash lights come on while trying to start?
Batery Voltage-Unknown but not very old, have had it replace within the last 2-3 years
Theft light blinks with key out of igintion
Stays on in start position
All dash lights on
Last week had sparks and wires replaced, and pwoer steering pump replaced. Has worked fine until this morning.
Theft light-when the engine is cranking the light stays on for about 3 seconds & then turns off
Starting-it turns & makes the "chug, chug" sound but never starts.
No aftermarket alams or remote start.
Ok we have ruled out the PATS anti theft system.
Describe this chug chug a little more, Does the engine turn over slowly or with normal speed but it does not even try to start?
Okay this rules out the battery as well. Now we must substitue a flammable spray for fuel. So spray a 2 second burst of brake cleaner or carb cleaner or ether into the throttle body while the throttle is held open and immediatly try to start it. If it starts momentairly this rules out the ignition for the spark plugs. This will leave you with check fuel pressure which is done witha gauge and hose hooked up to the fuel rail for the injectors and checking your fuel injector pulse. Below are is the injector test and another way to check ignition spark.
