Customer Question
It cranks but won't...

It cranks but won't start

Mechanic's Assistant: Have you checked the engine's fuel supply? And the spark plugs -- are they all working?

Yes I changed all the plugs and fuel filter when I checked to see if fuel is getting to the injectors there's no fuel getting to them.would a bad fuel pump cause this issue?

Mechanic's Assistant: What is the model/year of your Cadillac?

06 cts 3.6 rwd

Mechanic's Assistant: Are you fixing your CTS yourself? What have you tried so far?

I've changed the camshaft sensor I replaced all the plugs put new oil in it new fuel filter as well

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Yes if the theft deterrent is on for some reason will that cause it not to start

Now if the security light is triggered on will cause the no start Since will also cut ground to injectors
Is the key been recognized and the light goes away after key inserted ?
If not then you need a Gm tech II scaner to read anti theft and retrieve fault codes to pull up pin point trouble shoot and be accurate

Now if we are not getting fuel or injectors not pulsing but we do have spark , meaning CKP sensor ok, we can spray starting fluid in the intake and try to start if it start runs and dies , that means we have spark but no injector pulse since spray starting fluid in intake you by pass injectors .
