deville stalls-no codes
 

have a 03 deville (33K miles) that keeps stalling...read a lot of info here that it might be the crankshaft sensors, but I have no codes on my computer, so the dealership can't figure it out either. If the sensors do go out do they always leave a code? Cause most of the posts I see about the same thing all have codes. Any info would be good. Thanks.

Here's a simple one, when was the fuel filter changed last? Probably you don't know which means it 5 years old. There are so many impurities in gasoline these days I'd make sure it is not clogged up.

so if the fuel filter was clogged would that not leave a code on the computer? Will check into that, thanks for the tip.

Would not necessarily code.

I hope this solves the mystery...computer finally spit some codes out. P0385, P0386, P1372. Turns out was the crankshaft sensors, had extended warranty and they replaced. Just picked it up today so no chance to see if it dies again. Will probably go and change the filters too. Thanks again.
