Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
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.
Here is that BULLETIN 476307.
