Can you hear the fuel pump run for 2 seconds when you first turn the key to run before turning the key to start? If not the fuel pump relay probably isn't working and on that system, after cranking the engine over long enough that the oil pump builds up 4 psi of oil pressure, the oil pressure switch will override the fuel pump relay on run the fuel pump.

Well then it's not that then. A faulty coolant temperature sensor might cause this also. Is the check engine light remaining on?

I am reading a tsb that states, "

IF THE CRANKING TIME EXCEEDS TWO SECOND

S AND THE ENGINE DOES NOT START, THIS

EXTENDED CRANKING MAY BE CAUSED BY A FU

EL SYSTEM LEAKDOWN CONDITION. REFER TO

BULLETIN 476307 FOR ADDITIONAL

INFORMATION AND DIAGNOSIS."

Now let me see what that says.

Thanks a lot, but I have noticed it ran only for 2 sconds, no more.
I will check visually the Injectors, since I don't have the special tool they mentioned.
Cadillac Mechanic: Mike S., ASE Certified Technician replied 2 years ago

You might be able to rent or borrow some of those special tools, call you local auto-parts stores.

Thank you. My visual checks din't give me any info. There is no leak nor fuel smell near the injectors.
Don't you think there might be a faulty temp sensor? How can I check it ?
Cadillac Mechanic: Mike S., ASE Certified Technician replied 2 years ago

There is a Coolant Temperature Sensor is located Under hood, driver side, rear engine area, mounted on intake manifold.
